The HollowTech II 12-speed Dura-Ace chainset offers the optimum balance of light weight and rigidity, making it the global choice for road racing's elite riders Hollow outer chainring, giving vast improvements in rigidity and increased weight savings The hollow outer chainring has essentially removed outer chainring flex, hugely improving shift performance making it precise even under high load These industry leading HollowTech II 4 arm cold forged hollow crank arms have been evolved to increase rigidity, reduce weight, and improve strength The teeth have been developed to work only in conjunction with the 12-speed chains for...

Miche's unique system allows for a fast change of sprocket ratios. The splined adaptor screws onto the hub just like a normal cog, then simply slide the sprocket onto the carrier. Then both carrier and sprocket are held in place with the lockring. To change the ratio, simply undo the lockring and remove the sprocket. Slide on a different tooth size and refit the lockring. Because of the smaller diameter of a 13t sprocket, the actual sprocket is threaded and cannot be run with carrier. Made from Opaque chrome-plated steel Carrier is supplied Lockring sold separately

Shimano 105 chainsets are known the world over for their reliability and performance. Having been refined from the previous version the 105 R7100 furthers this reputation. For this edition, Shimano have carefully engineered the R7100 crankset to offer an excellent balance between stiffness, strength, weight, as well as rotational performance. The result is a chainset equally suited to big days riding in the mountains, as it is fast bunch rides. Trickledown Performance Thanks to the benefit of trickle-down technology, the difference in quality between a 105 chainset and the more premium Dura-Ace or Ultegra versions is closer...
