Bike Parts

On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored seatpost color is available on the Zipp Service Course Seatpost. Since the introduction of our line of Service Course and Service Course SL components, we've had amazing success with our pro-level athletes in all disciplines. While the successes have reinforced our design decisions, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering, we are proud to offer redesigned Service Course seatposts. - Material: 6061 aluminum - 2-bolt adjustability - Minimum insertion length: 90mm

The Wolf Tooth 107 BCD Chainring for SRAM Cranks is compatible with most new SRAM 1x road cranks that use the 107 BCD spider, including the SRAM AXS Power Meter Spider. This chainring uses the patented Wolf Tooth Drop-Stop B Wide/Narrow tooth profile that is optimized for drop bar bikes. - Fits 107 BCD for SRAM Cranks - Drop-Stop technology prevents dropped chains. On Wolf Tooth's patented wide/narrow chainring, the wide side of the tooth has maximum contact on the drive side which spreads the load and improves chainring life. The narrow side allows clearance for mud and debris while reducing friction. - Cranks that use the 107 BCD spider also use the SRAM 8-bolt interface, which is compatible with Wolf Tooth Direct Mount Chainrings for SRAM 8-Bolt More power, better traction, less shifting. Wolf Tooth oval chainrings use our proprietary PowerTrac design that has all the benefits of oval, but without the funky, uneven pedal stroke. Ride one once and you'll wonder why you waited so long to try oval. Think of an oval chainring as two chainrings in one. A major benefit of oval is how the shape of the chainring alters your gearing in two important phases of your pedal stroke by harnessing your body's natural biomechanics. Here's how it works. The area of the chainring with the larger diameter engages with the chain at the optimal point on the downstroke, which is what's known as the Power Zone. If you were to look at a clock, the Power Zone would be between 1-5 and 7-11. Conversely, the Recovery Zone – back to the clock face, between 11-1 and 5-7 – is the weakest part of the pedal stroke, when the oval maximizes your efficiency. A 34T oval chainring behaves like a 36T chainring when you want power, while behaving like a 32T chainring when you're climbing. We've also engineered our oval chainrings to provide smoother, more efficient pedal rotation. This equates to better traction because of steadier torque on the rear wheel. With a Wolf Tooth oval chainring, you can harness more of your strength in the Power Zone, while having easier pedaling in the Recovery Zone. - Use Drop-Stop B for all SRAM Eagle, SRAM Road and Transmission (T-Type) Flattop chains, 9, 10, and 11spd chains or 12spd KMC, Connex, Wippermann, Campagnolo. DROP-STOP B - Compatible 9, 10, 11, and 12s SRAM Eagle, 12s SRAM Transmission (T-type) Flattop, 12s Campy, 12s KMC - Not compatible with 12s Shimano HG+ chains Recommendations - - If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper (like our GnarWolf) in addition to a clutch-type rear derailleur. Without these precautions, you may experience chaindrops and/or chainsuck. - Recommend the use of a clutch-style rear derailleur for the best chain security. Tech Specs: - Material: 7075-T6 aluminum - Weight: 38t/75g | 40t/78g | 42t/86g - Made in the USA

The Wolf Tooth Post To Flat Mount Brake Adapter allows flat mount brakes to be added to a frame or fork that was designed for post mount brakes. This is a vital component for cyclists who want to run a road groupset on a mountain bike frame. - Please note that this is a +20mm adapter, which means a 140mm post mount native size will only work with a 160mm rotor, just as a 160mm post mount native size will only work with a 180mm rotor, and so on - Fits on post mount native sizes 140, 160, and 180mm - Works with rotor sizes 160, 180, and 200mm - Tested with SRAM and Shimano brakes - Requires minimum 13mm between top of brake boss to frame/fork - CNC Machined from 6061-T6 aluminum for strength and light weight - Includes : (2x) M5x13mm Flat Head bolts for Flat Mount Caliper and (2x) M6x15mm Socket Head bolts for Post Mount

The RoadLink DM (Direct Mount) is the RoadLink designed to fit Shimano's current generation R8000 Ultegra and R9100 Dura-Ace rear derailleurs. It serves as a simple device to offset the position of the rear derailleur, making it possible to run a wide-range mountain bike style cassette. It's an ideal solution for riders looking to convert their road, gravel, cyclocross, or commuter. - Fits Shimano R9100-generation Dura-Ace and R8000-generation Ultegra rear derailleurs - CNC machined from 6061-T6 aluminum with stainless steel bolt - Does not change the derailleurs total chain wrap capacity - Fits standard derailleur hangers only - Best used with Single or Double Setups - see manufacturer's site for more details
