Lighter, stronger, and better looking than our original Guiderings; the Guidering SL is intended for use on TRS, LG1, and legacy e*thirteen cranks. The Guidering SL is -8mm offset. This offset will achieve both boost (52mm) and non-boost (49mm) spacing on e*thirteen cranks that feature adjustable chainline (2019 and newer TRS & LG1). On legacy and XCX cranks the Guidering SL will achieve a 49mm non-boost chainline. - Direct Mount chainring for TRS and LG1 cranks - Updated M3 narrow-wide tooth profile eliminates chain noise, and decreases overall system wear while retaining chain - 10/11/12 speed. Compatible with both Shimano and SRAM 12-speed drivetrains - Allows both Boost 148mm and non-boost 142mm chainline on adjustable TRS and LG1 cranks SL Chainrings are not compatible with Helix cranks. Helix cranks require Helix rings.

Zipp’s SL Speed stem represents the essence of carbon componentry. It’s stiff, secure, and lightweight with a sleek design that complements any bike. It’s a perfect addition to a mountain climber’s favorite feather-light road bike, but it’s tough enough to tackle gravel and cyclocross. - Includes stiff aluminum faceplate and titanium hardware - Torx T25 heads for precise torque readings and ease of adjustment - Stack height: 41mm

- Replacement straight pull spokes for Zipp 88 (Front) and 188 (Rear) Hubs

Zipp's Tangente Cork Brake Pads are perfect for Zipp wheels with carbon braking surfaces. They are made of a composite cork polymer for consistent brake response and to reduce glazing from the intense heat caused by braking on carbon. As a result, the Tangente cork pads avoid the brake pulsation produced by residue buildup from rubber pads and can even eliminate pulsation from rims with previous buildup. These pads have a unique shape with more material in the front to improve durability and shed water. Although the composite material wears similarly to low-temperature rubber compounds, the Tangente cork pads last longer than most rubber carbon-specific pads because of the shape and 0.5 mm greater overall thickness.

"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. These chainrings are for Race Face Cinch cranks such as Turbine, Next SL, Sixc & Aeffect. The Wolf Tooth Cinch chainrings feature our patented Drop-Stop® tooth profiles for the best wear life, chain retention and mud clearance. We have optimized tooth profiles for SRAM T-Type Transmission, Shimano Hyperglide+, and all 12, 11, 10, and 9-speed chains. Compatibility - Any Race Face Cinch™ system crankset (including Next SL, Sixc, Turbine, Aeffect) - Riders running SRAM Transmission w/ Race Face Cinch cranksets with a Boost 136/137mm spindle use a Cinch direct mount 0mm offset chainring. - Riders using a Cinch crankset with a Super Boost 151mm spindle use a Cinch direct mount 3mm offset chainring. - Standard (142mm rear hub spacing) 6mm offset, Boost (148mm hub spacing) 3mm offset, and Boost for T-Type Transmission 55mm chainline 0mm offset are available. - Use a 3mm offset chainring for Super Boost applications running standard drivetrains or Transmission. - Wolf Tooth’s patented Drop-Stop® wide/narrow tooth profile for the ultimate chain retention and mud shedding ability. - For 1x9, 1x10, 1x11 and 1x12 drivetrains (including SRAM Eagle) --- If using a 9-speed drivetrain use a 10-speed chain (shifts and works well on a 9-speed drivetrain and fits the ring tighter for better chain retention). - Maximum diameter is that of a chainring 2t bigger than the size you order (so be sure there is adequate chainstay clearance!) - Chainline 49mm (standard), 52mm (Boost), 55mm (T-Type Boost) - Available in multiple tooth profiles for optimal performance based on your chain type. Use Drop-Stop ST for use with Shimano 12-speed Hyperglide+ and 12spd KMC chains. Use Drop-Stop A for all 9, 10, and 11spd chains or 12spd SRAM Eagle, KMC, Connex or Wippermann chains. Drop-Stop B is optimized for SRAM 12 spd Transmission (T-type) and Road Flattop chains but is compatible with all chains that work with Drop-Stop A. Recommendations - If you plan to ride in very muddy conditions, we recommend a chainguide or chainkeeper in addition to a clutch-type rear derailleur! Without these precautions, you may experience chaindrops and/or chainsuck."
