Zipp developed an extensive line of aluminum aerobar extensions to provide the perfect fit for any rider, regardless of size or riding position. Vuka extensions are designed to deliver improved aerodynamics by placing hands closer together and nearer to the rider’s head to start airflow over the rider sooner. Designed with input from top bike fitters, the shape of the Vuka Alumina Evo is crafted to feel as if the rider is shaking hands with the bar. This is achieved through the use of a multi-radius bend paired with a 20mm inward roll of the bar that can be adjusted to dial in fit and achieve an ideal position. - Clean internal cable routing for easy installation - Length: 360mm

Shimano's Ultegra Rear Derailleur delivers category-defining 11-speed shifting. At the heart of the derailleur is a light, tough, cold-forged-aluminum body with a wide, rigid pivot design that maximizes shifting speed and equalizes shift effort across the cassette. Smooth-spinning pulleys use sealed bearing to keep out the dirt and ensure quiet running in the miles to come.

ReMote Dropper Lever - Lever pivots on a 21mm ball bearing for smooth operation - Cable Kind Clamp does not damage secured cables and features captive hardware. - Includes barrel adjuster for on the fly changes - Engineered break-away pivot that allows the lever to break away from the pivot in the event of a crash.

It might look normal from the outside, but the engineering inside this incredible new chain design is anything but normal and it makes possible a gear range previously found only in 2-chainring drivetrains. And it’s also the biggest contributor to the Eagle drivetrain’s ultra-smooth, precise, durable and quiet performance. The Eagle chain’s links have a smooth radius, with no sharp edges or chamfers, which yield a significant reduction in noise, friction and wear on chainrings and cassette cogs. This design also allows for a flatter plate, which means more consistent chain riveting and greater overall strength. HARD CHROME technology extends the chain’s optimal performance life, and a Titanium Nitride coating on the Gold and Black models decreases corrosion and further reduces friction.

The SRAM NX X-HORIZON rear derailleur provides the same smooth, reliable shifting action as XX1—from the larger upper pulley offset to the 12-tooth X-SYNC pulley wheels. By eliminating unwanted chain movement, X-HORIZON shifts faster, puts an end to ghost shifting and reduces shift force and chain slap. And with Cage Lock technology, wheel removal and installation are easier than ever. - X-HORIZON design that reduces shift force, ghost shifting and chain slap - 12-tooth X-SYNC pulley wheels - Fully compatible with all SRAM MTB 1x drivetrains - Most affordable fully featured 1x rear derailleur in the industry - Speeds: 11-speed - Weight: 322 grams - Color: Black - Compatibility: X-ACTUATION - Bearings: Steel - Cage Size: Long - Max Tooth: 42

Shimano's Tiagra Rear Derailleur SS (10-speed) is sleek, balanced and consistent.

Shimano's Deore XT Rear Derailleur uses cold-forged construction and cutting edge technology to deliver crisp shifting, real-world reliability, and trademark precision. The Direct Mount uses less parts and provides a solid connection to your machine. The Shadow design tucks the rear derailleur closer to the wheel, which keeps it out of the way of roots and rocks as you're flying down the trail. A strong spring prevents chain slap, reducing noise while on the trail, and improving chain engagement when riding over rough terrain. Sealed pulley bearings keep things spinning smoothly, and wide plate construction prevents the derailleur from getting clogged with mud and debris.

Campagnolo's Record Ultra-Narrow Chain is light and quiet and delivers the finest shifting ever. This top-line model is perfect for Campy 10-speed drivetrains and features Ultra-Drive technology for shifting perfection. It also boasts excellent wear and flex resistance.

Be it the fireworks of a finale, an ideal rhythm, climbing on the top, or a deep, dark place extracting the last kilojoule of effort on your bike split, you want to adjust your gear with the twitch of a finger. eTap Blip satellite shifters allow you to shift when you want, where you want. - Limitless remote shifting positions for drop and aero bars - Wired shift buttons can be positioned however the rider prefers - Connect to Blip Box or drop bar eTap levers - Compatible with SRAM RED eTap shift/brake controls

The all-new SRAM RED chain was redeveloped from the ground up. The unique link shape allows the chain to be narrower and lighter while increasing strength and providing more space between the outer plates of the chain and the cogs on either side. The result: a quieter chain with faster, more precise shifts. - Flattop technology enables a narrower chain with quieter operation and increased strength and durability - Hard Chrome plated inner link plates and rollers for reduced wear and prolonged life - HollowPin construction for increased strength and efficiency - Chain length: 114 links

With SRAM's XX1 Chain, it's 1 x 11 all the time, so the chain can be narrower, stronger, faster — all because it doesn't have to deal with high-stress, front chainring shifting. Since it only has to do rear shifts, gear changes are telepathically fast and feathery light. Its "wide tooth, narrow tooth" pattern perfectly matches SRAM's X-Sync chainrings so dropped chains and cumbersome chain-guides are a distant memory. The durability and weight is impressive, too, with SRAM's Hard Chrome tech, hollow pins and a proprietary link finish for improved life span.

Shimano's 105 Rear Derailleur delivers high-end function with upscale looks. With a body of light, durable cold-forged aluminum in Shimano's wide-pivot design with their light-action spring, rear shifting is practically effortless and always super smooth. The top pulley stays a uniform distance from each cassette cog ensuring that every shift resonates with the plunk of exact gear engagement.
