Top Features of the Shimano Ultegra 6750 Hollowtech II Compact Chainset
- Industry leading HollowTech II cold forged hollow crank arms have been evolved to increase rigidity, reduce weight and improve strength
- A wide range of chainring options and crank arm lengths are available to meet the needs of all riders and racing disciplines
- HollowTech II integrated bottom bracket uses a wider bearing placement and larger axle diameter for increased stiffness and efficiency
- HollowTech II integrated bottom bracket seal design has minimal bearing interface ensuring smooth rolling and increased durability
- Weight including bottom bracket 785 grams
|Bottom Bracket Type:||Hollowtech II|
HollowGlide hollow outer chainring gives vast improvements in rigidity by virtually removing outer chainring flex and hugely improves shift performance, even under high load.
The chainring teeth have been developed to work in conjunction with the CN7900 and CN6700 chains for increased contact to provide greater efficiency and improved power transfer.
Your chainset must fit onto your bottom bracket! There are currently four chainset/bottom bracket interfaces that you're likely to come across. If your bottom bracket is made by Shimano and it has splines, then you need an Octalink chainset. If your b/b is NOT made by Shimano and it has splines, it's almost certainly ISIS. There are a very few non-Shimano chainsets with Shimano Octalink interfaces so, to be sure, count the splines - ISIS has 9, Octalink has (surprise, surprise) 8. No matter which brand of b/b you have, if it has a square interface, it will require a traditional square taper chainset. If you have one of the new Hollowtech II systems, you will need to choose the exact chainset that matches your bottom bracket. Most MTB chainsets are now 9-speed compatible but these will work with an 8-speed system.
