Cheaper solid-axle hubs use serrated flange nuts, or plain nuts with serrated washers. The washer is permanently attached, but can rotate with respect to the nut. Track Nut An axle nut with a built-in washer loosely riveted to it. Track Mitts British term for fingerless cycling gloves. There are several different threads used for the left-threaded lockring, including: The idea is that if the sprocket should start to unscrew, it will turn the lockring with it, tightening the left-hand thread, preventing the sprocket from unscrewing. Track hubs have a stepped thread, with a standard 1.37" x 24 tpi thread for the sprocket, and a smaller, left-hand thread for a locknut. The Japanese variant, Keirin, is a major betting sport. Common track events include match sprints, pursuits, motor-paced events and miss-and-out races. Track bicycles have steep angles, fixed gears, and no brakes. Track An oval track, also known as a "velodrome" for bicycle racing. Thin-wall (high TPI) tires tend to be lighter and have lower rolling resistance, but they're more easily damaged by road hazards. The higher the TPI number, the thinner and more flexible the tire fabric is. Threads Per Inch, the pitch of a threaded fastener.Armed with this knowledge you can make an informed decision at your local bike shop to get the best tires for you.Opinions and value judgments are our own, unless otherwise notedĪdditions and corrections are most welcome.Ī - B - C - D - EF - G - H - IJKL - M - NO - PQ - R - S - T - UVWXYZ Up to previous page Your bike or your riding may not accommodate every recommendation above, and that's okay. It's not huge, but every little bit counts. 100g might not seem like much, but that's 200g across both wheels which is about 1/2 pound. Say you're comparing two tires of similar price, 100 grams different in weight. Ultra light tires exist but sacrifice durability, while over built tires add unneeded weight. 200 - 300 grams per tire is our recommended range for city riding.

While tire weight is a small part of your overall bike weight, it can make a difference. And because the threads are a bit more delicate, the tire will wear out sooner.Ħ0TPI - 160TPI covers a broad range of tires, giving you access to the benefits of each casing type. This makes the tire lighter and more flexible so it grips the road better - we say it "performs" better - but it's also more susceptible to flats. That inner nylon casing has a thread count - threads per inch (TPI) - that has a large impact on the tires performance and durability.Ī low thread count tire (say 100) has finer threads and less rubber. Save your money, $30 - $50 will do you just fine.Ĭontrary to popular belief, tires are not constructed of rubber. Alternatively, while there are plenty of tires above $60, they're usually over designed for commuting. Anything below $20 will likely have a short life and isn't worth the hassle. As you'd expect, the higher the price the higher the quality. In that range the tire is firm and fast, but not so hard it's jarring and uncomfortable.īe prepared to pay anywhere from $20 - $60 per tire. For 700c tires we think the sweet spot is between 100PSI - 120PSI. We like 23mm - 28mm.Īs anyone who has gone a few weeks without pumping up can tell you, tire pressure - measured in pounds per square inch (PSI) - makes a big difference. Bouncing around, rather than moving forward, isn't comfortable or efficient. Big squishy tires don't immediately equal comfort.

That means thinner tires are often more firm, reducing rolling resistance and conserving energy as you ride. As tire width increases (say from 23mm to 28mm), the maximum allowable pressure decreases (say 110PSI to 85PSI). Your diameter is fixed, but you have lots of options for width so lets start there. That tells you the tire d iameter x tire width. What you're looking for are two numbers separated by an "x". Your tire size will be listed on the sidewall, but can be hard to spot. To find your tire size, grab your best monocle and embrace the floor. To start, different types of bikes have different sized tires. Read on for our recommendations to make tire shopping easy. If this sounds like meaningless jargon fear not, we've oversimplified the process. So why is something so essential so often misunderstood? Size, PSI, TPI, weight, price. No matter what kind of bike you ride or where, your tires affect your commute.
