- Lightweight anodised SG-X aluminium chainrings for smooth and precise shifting
- For use with ST-5703 or ST-6700
|Bottom Bracket Type:||Hollowtech II|
The triple chainring teeth have been developed to work in conjunction with the CN-5600 chains for improved up and down shifting. HollowTech II allows the bottom bracket bearings to be spaced wider apart (outboard from the frame), enabling the use of larger bearings and an increased axle diametre.
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.

Product Q & A
Ask your questions and share your answers.
Also does this come with the bottom bracket? or could you run it with an Ultegra bb? Thanks
The bottom bracket will need to be purchased separately however an Ultegra BB should fit without issues.
This will allow us to answer you in more detail.
The teeth of the chainrings are narrower so they fit through the smaller gap in the narrow 10-speed chain. This means that you probably can't run narrow 10-speed chain on an older wider 9-speed crankset, but wide chain on narrow teeth are no problem at all.
I've been running a 6700 crankset with an otherwise 6500 9-speed group for a few thousand km, and it has been great.
