With this completely redesigned model, the Record Front comes equipped with a leverage system that guarantees fast shifting. What's most impressive is the micro-adjustments to the front derailleur position, which make upshifting and downshifting effortless, on steep slopes and unexpected road conditions.This high-quality front derailleur is compatible with tyres up to 32mm, thanks to a new upper connecting rod and optimised design. The Campagnolo Record Front Derailleur (12 Sp) is the perfect choice for keeping your riding at its peak performance, ride after ride.Features: Forged aluminium construction and steel screws. Upper connecting rod not connected to the external one: More effective, precise movement, without contacting the limit stop. Cage plate designed to improve occurrences of maximal chain crossing: The derailleur avoids contact and friction with the transmission. Ideal for wider tyres: Tyres of up to a 32 mm cross-section can be fitted without risking contact with the front derailleur. Optimised inner cage plate design: Accurately accompanies the chain on the largest chainring. Cable fixed in double position: Maximum compatibility with frames.

Designed around the extra 2 gears in a SRAM True 22 setup, the SRAM Force 22 rear derailleur works with the Yaw front derailleur to ensure fast, smooth, quiet and efficient throughout all 22 gears with no chain rubbing or excess noise. With WiFLi, the rear derailleur lengthens its cage and gets a slight variation in geometry to accommodate an 11-32 cassette. The new range of gears is wider than the standard triple chainring system and saves a significant amount of weight. Using Exact Actuation, each gear shift is fast and accurate, with the redesigned AeroGlide jockey wheels keeping things quiet and smooth. Carbon and aluminium cages, along with a magnesium inner link keep the weight very low at only 178g.
Crisp, clean, correct shifting, always: the most precise gear change in cycling is here with the Sram Force Rear Derailleur. The Sram Force Rear Derailleur takes advantage of Exact Actuation, an actuation ratio that delivers precise 3mm shifts in every gear along with the widest range of adjustment available, delivering the best 10 speed performance in the sport. The Sram Force Rear Derailleur is crafted with cutting-edge materials, including a unidirectional carbon-fiber outer cage and a magnesium inner link, resulting in an impressively light 178g weight.Exact Actuation means precise, even gear changes throughout the shifting range.Carbon-fiber outer cage and magnesium inner link give strength and light weight..Speeds10.MaterialAluminum B-Knuckle, Magnesium Inner Link, Carbon/Aluminum Cage.Weight178g.Technology Highlight(s)Exact Actuation.

With the new Super Record, Record, and Chorus groupsets, shifting is extremely easy thanks to the long front plate of the front mech body, meaning greater leverage and therefore truly reduced movement when shifting. Shifting precision is achieved thanks to the design of the new narrower cages. The semi-inner cage, in aluminium, has features that improve shifting speed. The most efficient downshifting on the market is achieved thanks to the integrated outer semi-cage in carbon fibre, a distinctive Campagnolo feature on the Super Record and Record front mechs, or by the positioning of a plate on the tip of the Chorus front mech. S2 System (Secure Shifting System) The special support system built into the derailleur safeguards working of the drivetrain, guaranteeing maximum compatibility with frames on the market. Special Inner Cage Design The inner semi-cage, in aluminium, has features that improve shifting speed, give greater rigidity and provides more space for chain crossovers
SRAM Force CX1 11 Speed Rear DerailleurThe Force CX1 11 Speed Rear Derailleur from SRAM adopts all the technologies of SRAM 1x mountain bike technology to provide the fastest, quietest and smoothest 1x11 shifting available.SRAM's unique clutch system eliminates chain slack, providing for smoother, quieter, and more secure chain travel. 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. Cage LockWith 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 ClutchRoller 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. Exact Actuation (EA)When SRAM launched their road technology from scratch SRAM re-applied their mountain bike (MTB) proven SRAM 1:1 actuation ratio (shifter cable travel: derailleur movement) for 10 speed rear shifting. EA helps to simplify/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-HorizonThe 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. X-SyncSRAM X-Sync 1X chainrings provide the highest level of performance and durability. The SRAM X-Sync tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-Sync chain rings 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 drivetrain. Features: A dedicated 1x rear derailleur for cyclocross Exact Actuation for fast and accurate shifts using SRAM's 1:1 actuation ratio (shifter cable travel: derailleur movement) 10 and 11 speed compatible X-Sync pulley features a 12-tooth design that helps control the chain's lateral movement X-Horizon "straight parallelogram" design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force Roller Bearing Clutch technology Cage Lock technology Weight: 261gBuy SRAM Components from Chain Reaction Cycles, the World's Largest Online Bike Store.
