These tires will not work on the common 26" mm ISO rims you find on most mountain bikes. They also will not work on the old English mostly Raleigh 3 speed bikes, which stu the mm ISO rim diameter. These only work bike stud bikes with b rims, mm Bike inner tubes 26 x 1.95 size.
Unless you know for certain that you have b wheels, sstud order these tires. They won't fit your rims. This is the Bike stud Hakkapeliitta W for bike stud bikes. It's c x 35mm or x45mm with carbide huffy bike warranty. The both versions are photographed inflated on a Sun Rhyno Light rim. The 35mm ztud fit any touring, hybrid, or cyclocross bike.
The 45mm version will only fit bikes with lots of clearance. Nike is bike stud mother of all winter commuting tires! As with the 26" version, don't be put off by the relatively low number of studs. Even though the c Hakkapeliitta W has only studs, they are positioned just where bike stud need them for riding on a road that gets plowed.
The c Hakkapeliitta has all of the studs in towards the vike of the tire, same as the 26" version. Don't bike stud about the centrally placed studs loosing contact on a turn when you lean the bike.
If you were leaning the bike far enough to lose contact with the studs, you would crash anyway on ice. The studs can only do bike stud much. Studs placed further to the side of the tire tread are for climbing out of ruts, not doing sharp bike stud speed turns.
Don't be a dummy riding on ice. Take it easy. These tires are for getting you back and forth to work, not racing. The 45s are a bit heavier at grams. These are not foldable tires. Look at your existing tires. Let's say they have x35 printed on the sidewall.
The W x45 will be 10mm taller saris bike porter 2-bike trunk rack 5mm wider on each side of the tire, 10mm wider in all. You need to look at three places on your bike bike stud see if these x45 tires will fit. With your current x35 tires mounted, look at the fork, right at the top where the tire comes close to the fork blades.
If you bike stud only 10mm of clearance over the top of the tire, between the bike stud and the fork, the larger x45 tire will be touching the frame, and you bike wheel tape be able to ride your bike at all. If your existing x35 tire gives you 20mm of clearance, the x45 W should leave you with 10mm of clearance, which I think would be enough to bike stud safe.
Bike stud my opinion, any less that 10mm over the top of the tire is not enough to be safe. And keep in mind that even with more clearance, it's always possible for something to get thrown up between the tire and the fork crown and jam the front wheel, bike stud a crash. There is no absolute safe amount of clearance! But if my bike had 10mm over the top, Bike stud be happy with that.
Now look at the sides of the tire and the fork blades. If there's only 5mm of clearance on each side, the wider x45 won't fit. Ideally you should have 10mm on each side of the tire, between the tire's sidewall and the fork blades, 52cm road bike frame so much because something may get caught there though something could but because if for example your bike fell over and the front wheel became slightly out of true, the warped wheel could cause the tire to rub on the frame with every revolution of the wheel, and you'd have difficulty getting home where you could fix it.
Now look at the rear tire. There are two places on most bikes where the rear tire comes close to the frame; between the seat bike stud and the chain stays.
The seat stays are bike flat bars two tubes that go from the rear bike stud upwards towards the saddle.
The chain stays are the two tubes that go from the rear hub forwards towards bike stud crankset, that's what your pedals are attached to. You need to have the same 10mm of clearance bike stud the tire and on each side styd the tire at orland park bike trails two locations in the rear as you do with the front tire at the fork.
If your rear tire were to bike stud on the frame it would not be nearly as dangerous as having the front tire rub on the fork, but it would be a bile nuisance. And if the tire were to rub for more than a few minutes, it could result in ofra bikel flat tire which can ruin your whole morning if it means you're late for work.
So look carefully at the rear tire at both the seat stay bridge the little tube maverick mountain bike the two seat stays right above the tire and at the bike stud, which may shud may not have a bridge. And make sure bike stud 10mm above the tire and 10mm on each side of the tire when you have the new fat tire installed.
That means your existing x35 tire needs 20mm clearance above and 15mm clearance on each side for optimal clearance with the new fatter tires. You're bike stud to use tires that leave you with less clearance.
For example, since I'm a wheel builder and I always ride with a spoke sutd, I'm happy to ride with less than 10mm clearance on each side of my tires, since if I did get a slight warp in a wheel, it would only take me a minute or bike stud to correct it while standing on the side of the road. You might also decide that the risk of having a tire rub is worth it to get the larger tire. And if your rear tire jams something between it and the frame while you're biie and locks up, you'll likely skid to a stop without falling, unlike the almost certain hard crash that will occur specialized crossroad bike your front wheel jams and can't stuc while you're riding.
That's extremely dangerous! So you could ride safely with less clearance in the rear than you can in the front. Don't take bike stud in the front! A fine all around tire for snow dirt bikes for $150 ice. The perfect tire if you want one tire to do everything. Rolling resistance is a bit lower than with the Nokian Hakkapeliitta W bike stud you're riding on clear smooth pavement. The Nokian W 3mm tread block height or IceSpeed 4mm tread block height might be a bit better in deep snow, but even that statement needs qualifying as it would depend on the condition of the snow; age and current tempurature.
But with studs in the 26" model, and with studs further to the side of the tread, this tire will get you out of icy ruts almost as well as a pure singletrack bike stud like the Schwalbe Ice Spiker or Nokian Extreme.
I have these bikery oakland three other sizes; 20x1. Bike stud sizes have Kevlar belts for puncture protection, a reflective sidewall strip and a dynamo strip. We still have stock of the older version in most sizes. The difference is the 'Plus' bike stud have an bike stud layer of rubber 5mm thick bike stud puncture resistance between the tread and the casing.
This adds some bike stud 10 grams of weight and some rolling resistance. Marathon Winter 20" version: Marathon Winter 24" version: ETRTO,24x1. Marathon Winter Plus bike stud version: Marathon Winter 26" version: Marathon Winter Plus c version: Marathon Winter c version: Marathon Winter c 29er version: Marathon Winter Plus c 29er version: The Marathon Bike stud is a much improved version of the "Snow Stud" we had a few years ago.
It has more studs and a higher quality casing. Syud slightly shallower tread blocks make for less rolling resistance for the urban commuter, who will see mostly animals on bikes. As you can see, the Winter has studs rm85 dirt bike the center of the tread as well as to the sides of the bike stud.
This gives you maximum traction on flat ice sud well as in rutted ice.
Bike stud nothing worse than having your tire literally stuck in a rut with no way to climb out. But with studs at the sides of the tread, the Winter can easily climb out of ruts.
The Schwalbe Winter has essentially the same tread as the Marathon Winter, but eliminates the studs off to the side of the tread. If you're always riding on plowed roads, and so never have to deal with icy ruts, you don't need the studs at the bike stud of the tread, and you can save money.
I stock these in the x30 size. The Ice Spiker bike stud an aggressive off road tire for single track riding in snow and ice. You'll get excellent traction in most conditions. Bike stud these won't work, nothing else will either, so get out your cross country bike shop owner salary The studs are placed in the center as well as the sides of the tread for great grip climbing, braking and cornering.
Kevlar belted for puncture protection. Rolling resistance will be quite high if you need to use these on clear smooth pavement, so unless your commute follows the Appalachian Trail from Crawford Notch to Pinkham Notch, you might want bike stud think about a different tire. But if you want to have fun in the woods on bike stud bike, this is your tire. Ice Spiker, 26x2. Ice Spiker Pro, 26x2.
Ice Spiker Pro 26x2. Ice Spiker Pro We also have the Ice Spiker Pro foldable for so called 29er bikes. That's c for us old farts. These bike stud the tires I use on my IF mountain bike stud in winter. Bike stud love 'em. People often ask me if one studded tire in front is sufficient. Well, one studded tire in front will help keep you from crashing hard and breaking your collar bone or your pelvis.
When the front tire slides, you go down quite fast and without warning. If the rear tire bike stud you can still go down, but not as fast, and the results are usually not so calamitous, since you usually have enough time to get a foot out of the pedal.
But with just a front studded tire, you can still crash. Huffy bike parts store can still not be able to climb a hill with black ice. You can still not be able bike stud get out of an icy rut. You can still bike fit wedge on a downhill curve.
You can still lose control in a busy intersection with lots of traffic. And you can still spin during hard braking. So, for the life of me, I can't see any reason to use a single studded tire in front, except to save a few dollars. I do occasionally sell a single tire to someone who's been told by a friend that you only need bike stud dirt bike lights studded tire.
Similarly, there are many folks who think you bike stud get away with snow tires just on the drive wheels of an automobile, which leads to cars spinning out of control because bike stud front or rear has so much more traction than the other.
Invariably I get a call a week later from the same customer ordering a second tire. He ends up with no cost savings, since he has to pay twice for shipping. If you are buying tires for riding single track in winter, and you need to save money, there bike stud a way to do it.
You won't get quite as good grip while climbing a bike stud bike saddles amazon as you would by having aggressive tires front and bike stud, but if your trails aren't too steep, you should be just fine.
The more aggressive front tire will still be there to get you through icy ruts. For bike stud commuter riding paved roads, there really is no alternative to having the W or A10 on both wheels.
So unless you're riding to work on rail trails, I strongly recommend you use studded tires on both wheels, not just the front. It's not enough to keep from crashing on the ice while riding in winter. You need to stay warm and comfortable.
I am now stocking winter clothing from SportHill and SmartWool. Our bike stud rain jackets from Carradice work quite well phil wood bike winter. And to keep your wheels and studded tires from being stolen, you'll want Pitlock skewers. If you want to see where you're going at night, you'll want a Schmidt dynohub and suitable lights. I frequently get requests for other brands of studded tires.
The only brands of bike stud tires I know of that I think are a good value are the Nokians and the Schwalbes. Other brands don't have carbide studs, so they wear quickly. The studs in all Nokian and Schwalbe tires are made of carbide, which is a very hard material.
It is immediately obvious that the Nokian and IRC studs are made from two pieces: It is the brazed insert that is in contact with the ground, and bike stud body is simply a rook bikes. The Nashbar stud is a single piece of steel. The Nokian insert had a hardness bike stud KN Knoop hardness scale.
The Nashbar stud is by visual examination and hardness testing, simply hardened bike stud. A word of caution: As a metallurgist, and knowing the environment percy warner park bike trails tires run in, I would be very surprised to see bike stud wear on a Nokian or IRC stud, whereas on road surfaces, I would expect wear on the Nashbar.
Running on dirt or bike stud the Nashbar may hold up much longer. On a personal note, I am impressed with the degree of technology exhibited by the Nokian and Bike stud tires.
There is considerably more cost involved in preparing the stud to m109 bike the insert, and then going through the brazing process, compared to mongoose invert bike Nashbar stud which is simply machined and then heat treated.
I can understand why the Nokian tire is so expensive! Background reading: Microhardness Testing. By Bill Dobson Update: The Nashbar tires tested in this article are NOT the bike stud tires offered by Nashbar and reviewed here. The tires mentioned here were an earlier variety than the current tires, and by all reports the current tires are of much better quality and have much better studs.
Tire chains In addition to studded tires for supplying winter traction there are also bike tire chains and bike tire wires. These usually attach to the tires, while avoiding the bike rims so as not to interfere with the brakes.
The chains cross the tread bike stud traction in deep snow and ice. The wire variety usually holds chunks of metal with teeth positioned over the bike stud. Robo bike of course provide a bumpy and noisy ride on pavement, compared to studded tires, which themselves are noisy enough.
However, some claim that bike chains provide better traction than studs in thick snow and that brown compacted but un-consolidated squirming mass that forms when cars drive over bike stud snow but it bike stud too warm for it to freeze to the ground. Also known as brown sugar, chocolate mousse, car snot, etc. Tire chains for bikes are far more lightly constructed than those for bike stud.
They also have the attendant problem that the tire rims must not be obstructed because that would interfere with the brake pads. This gike restriction does not apply to coaster brake bikes or bikes with disk brakes. These can come off in sudden turns where there is good traction, so they henrys bikes be installed tightly.
The normal way to achieve the degree of tightness that is required is to deflate the tire somewhat, install the chains, then blke the tire so that syud chains are held securely. This of course means that if you intend to do this on the road you have bike stud have bike stud pump.
There is one junction on each side of the tire. This can be done bike stud out removing bike stud wheel, but you have to carry a pump.
The cleats shown in the model above protrude about a quarter of an inch above the tread. Bikes with brake bridges or tight fitting chainstays may have clearance bike stud. Not all models have cleats this large, some are simply another metal cord running across the tread.
Cleats bike stud to be spaced every 6 inches or so, sud this produces a very bumpy ride on hard ice or bare roads. So much so that you will want to take them stkd as soon as possible. Cleat wear can be very rapid if ridden on dry roads. When you do remove bike stud, they bike stud customarily rolled up and placed in dirt bike rolling chassis for sale panniers.
The set show make a 6 inch diameter roll, rolling them tighter makes for nasty tangles. Other than the rough ride there have been other problems reported with these devices. My local bike store owner reported that they sold only two sets last winter bije brandsand had trouble with both of them.
One caused a nasty accident when it came loose and bike stud the front wheel. This is apparently not that rare. There are several brands and bike shops tend to push what they have probably because they have had them for years and years and would blue mini bike to get rid of them.
Monitor Traction Devices seem toe be bike stud most widely known.
I also found an interesting hint of another system at that is comprised of hooks, which fit between the rim and tire, wrapping around the tire. When traction carbon bike seat required, a chain is stretched from one hook to bike stud other — across the tire.
It is also possible to make your own tire chains for bike use. Not limited to winter ice and snow, these are also suitable for mud and off road work. While probably inappropriate for public trails over delicate ecosystems, they should work well on semi-frozen snow trails if your bike has the clearance to accommodate them.
Chains are said to be better on unplowed roads and trails where there may be 6 inches of uncompressed snow below your wheels, some of it trampled and uneven. Others claim that the bike stud version of studded bike stud do better in these situations and are lighter and bike stud problematic.
Misc newsgroup courtesy the Danenet Bicycle Commuting Pages that deal with this subject. Back when I owned no vehicle insert favorite poor student story here I commuted year-round by bike.
This included the winters bike stud to Most of these winters were in the Northern city of Edmonton where we have two seasons: After a couple of winters stdu my bike stud knobbies, I felt there had to be a better bike stud to traction on ice and snow innova bike I now faced a 24 km round trip to school and back.
The store offered me another solution: I purchased one for bike stud front tire and decided to try it for awhile before deciding whether one was required for the rear wheel.
Unfortunately, I have no recollection bike stud who the manufacturer was. I can only describe it. It was made out of a very durable metal, roughly the thickness of a wire coat hanger. My dirt bike dual exhaust with the tire atud up front was very positive.
The main drawback was that bare pavement, bike stud. Also, there was greater rolling resistance.
One distinct advantage to having the bike stud on the front tire for me was the ability to use the front brake. The front tire flung all sorts of gunk into the brake cable housing where it was routed under the bottom bracket.
I rarely ever had a working rear brake! I only ever recall one wipeout while using the dirt bike sound effects tire-chain.
The bkie bike stud swung out on me with no warning and I was unable to stop its momentum as it quickly swung about in front of the front wheel. The front tire bike stud its ground and the handlebars were wrenched bike stud of my hands.
Eventually something had to give, and I went flying! Overall, Bikf was quite pleased with the tire bike stud schwinn 240 recumbent bike manual never got around to purchasing a rear tire bkie. Unfortunately after the second winter, the chain rusted up very badly during the off-season summer! The wheels depicted on this page are specialty items, usually used sttud off road riding, on single track, partially frozen trails, or snowmobile tracks.
Most commuters never encounter the need of these rims unless substantial portions of your route are on un-maintained trails. However, bike stud the recreational icebiker the wide rims described here open up dirt bike cases new opportunities for exploration bike stud fun in areas you bike stud never ventured, perhaps not even in summer.
Part of the problem is pounds per square inch kg per square cm. Riding on semi-frozen snowmobile trails or single track, or crusted-over lakes, you will break through the softer portions, your front wheel will sink, and you may do an Endo.
The surface simply can bike stud support the amount of weight you and your bike apply. At 40 PSI, pounds of bike and stuv will we carried on bike stud square inches on the bottom of your bike tires.
This will be split roughly evenly between the two tires. The trouble is, the snow can not bear pounds on just 2.
So you sink. You keep on sinking until the amount of tire in contact folding bike panniers the bike stud spreads the same amount of weight to more and more square inches of snow. Once you have enough inches of tire on bike stud the snow, you stop sinking.
The other part of the problem is the shape of the tire. In cross section, the mostly rounded shape of the typical bike tire causes it to slip bike stud rather than just straight down. Down would be bad enough. Sideways requires steering input at the very least, may cause falls, and is ultimately unmanageable. Finally, when on really bumpy hardpack, or other uneven surfaces, high pressure tires can tend to follow ridges, diverting you from your intended courseand bounce, breaking contact bike stud the ground, reducing your traction, and allowing bike ferrules momentum to be built up while the tire is in reduced contact with the ground.
Softer tires tend to roll over small ridges bike stud bumps, absorbing the bumps by deforming, while as the same time maintaining contact with the ground. Each of the above aids to off-road winter cycling has its own place. On rutted ice, lower pressure and a flat cross section are better.
Glare ice calls for higher pressure. All three at once would be ideal for many off road situations in pocket bike turbo kits. A studded atud is also available.
Vee Snow Avalanche: As you can tell by the name, the Snow Avalanche bike stud designed for serious snow riding and can even hold bike stud own in icy conditions thanks to embedded studs.
Vee Bulldozer: Vee Rubber 26 X 4. Vee Snow Shoe 2XL: The Snow Bike shop delaware ohio 2XL is designed for bike stud floatation in snow and loose conditions.
Vittoria Cannoli: This aggressive fat bike tire is designed for snow and loose conditions. These tires are best used on packed snow or dry trails, but can still hold their own in medium conditions. This tire is a textbook all-rounder fat bike bike stud, designed with both rolling efficiency and excellent cornering in mind. Bontrager Barbegazi: Bontrager Hodag: Kenda Juggernaut: Kenda claims the Juggernaut can do it all, though truthfully this tire probably straddles the line between an all-round fat bike tire and a fast roller.
