The Shadow features a super low profile design that reduces the risk of damage from trail side hazards and the single tension spring prevents contact with the chainstay resulting in a silent ride.
This Campagnolo original component is an idea replacement for your worn or damaged 10 speed Chorus or Record Chainsets.
Campagnolo is pleased to introduce the latest addition to its line-up of finely made mechanical groupsets and this newest entry goes by the name of CENTAUR. While attentive fans of the Italian brand are sure to note that this is not a new name but rather one that has graced the catalog in the past. The newest version takes a huge leap forward and represents even greater value and performance than any preceding version ever made. The Campagnolo Centaur 11 Speed Cassette has had its tooth profile completely redesigned to be in line with the rest of the Campagnolo 11-speed groupsets. The sprocket tooth design reduces the level of stress on the chain, which ascends more easily onto the higher diameter sprockets; even when shifting across increments of 3 or 4 gears at a time. If you want a race ready cassette at a price that wont break the bank then this is the perfect choice!Material: AluminiumFinish: Nickel, chromeSmooth shifting tooth profileWeight: 291g (11-29T)
The Shimano Deore XT M8000 rear derailleur receives a complete makeover and as a result it features Shimano's pioneering Shadow RD technology and a refined geometry for increased stability. The Shadow Plus rear derailleur follow the range topping XTR in providing a lighter shift effort, with external adjustability and increased clutch tension range, and an even lower profile for improved clearance from trail hazards. The derailleur provides a light action through the shifter which results in a positive and perfectly executed shift as well as a smooth journey throughout the cassette.

SRAM Apex 1 11 Speed Rear DerailleurThe SRAM Apex 1 Rear Derailleur brings the simplicity of mountain bike gearing to your Road, Hybrid, Gravel or Cyclocross (CX) bike so you can go where you want. Compatible with up to a 42T cassette, it will help you tackle the toughest terrain and the steepest climbs. Also, thanks to SRAM's Exact Actuation™, X-Horizon™ technologies, you'll enjoy fast, precise and reliable shifting.Features:Material: Aluminium cageCage Length/Type: Long cage fits up to a 42-tooth cogSpeed: 10 or 11-Speed SRAM Road drivetrainsClutch Options: Roller Bearing ClutchIntended Group: Apex 1x11Max Tooth: 42TPull: X-Actuation™Pulleys: Sealed cartridge bearingsCompatibility: Compatible with 10-speed and 11-speed SRAM 1x™ road systemsTechnology Highlights: Cage Lock™, Roller Bearing Clutch™, Exact Actuation™, X-Horizon™, X-Sync™Weight: 314gPart No: RD-APX-1-A1Technologies:Cage Lock™: With Cage Lock™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just push the cage forward to create slack and lock it into place.Roller Bearing Clutch™: SRAM's rear derailleurs with this technology deliver maximum drivetrain stability—even through the most punishing terrain. With Roller Bearing Clutch™ technology, derailleur bounce and chain slap are eliminated without sacrificing precision.Exact Actuation™: When SRAM launched their road technology from scratch, they reapplied their mountain bike (MTB) proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement). Exact Actuation™ helps to simplify and stabilise the uneasy act of balancing rear derailleur hanger design, tight cog spacing, and exact cable tension. The result: the easiest index shifting system to set up—and it stays that way.X-Horizon™: This technology gives the rear derailleur a ‘straight parallelogram’ design, which limits all movement to the horizontal axis, making ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.X-Sync™ Pulleys: SRAM'S 1X X-Sync™ pulleys and chainrings provide the highest level of performance and durability. Their tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. Their sharp and narrow tooth profile, as well as their rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync™ chainrings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-Sync™ rings are an integral part of the SRAM 1X™ drivetrainBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
The SRAM NX rear derailleur provides the same smooth, reliable shifting action as SRAM’s XX1 model - from the larger upper pulley offset to the 12-tooth X-SYNC™ pulley wheels. By eliminating unwanted chain movement, its X-Horizon™ cage 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. Technologies: Cage Lock: With Cage Lock technology in the rear derailleur, wheel removal and installation, as well as chain installation, becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place Roller Bearing Clutch: Roller Bearing Clutch (RBC) rear derailleurs deliver maximum drivetrain stability—even through the most punishing terrain. With RBC technology, derailleur bounce and chain slap are eliminated without sacrificing precision X-Actuation: Developed specifically for SRAM 1X, X-Actuation keeps shifting sharp and consistent across the entire 10 to 42-tooth cassette X-Horizon: The X-Horizon rear derailleur’s ‘straight parallelogram’ design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears
The SRAM Apex 1 rear derailleur makes that perfect gearing choice a reality with clean, crisp shifts, thanks to SRAM’s X-Horizon™ geometry and the Roller Bearing Clutch™. Just go: Apex 1 will get you there.
