Thanks for looking at this phenomenal bit of kit. With dual sided power measurement and features like torque vectoring you can really take your training to the next level. This is the unit that Team Sky now use and is not to be confused with crappy things like a Stages meter.
It is a standard Dura Ace 9000 chainset with 24mm axle so no need for different bottom bracket sizes, you just fit it as per the instructions and go. The crank lengths are 175mm and it is currently fitted with some 52/36 chainrings but I could change them out for 53/39 or 50/34 if you wanted. Not sure what else to say about these other than check out the reviews on line and see for yourself or drop me a message if you have any questions.
