Today’s column will review finding the right BBRight adaptor and making a 10-speed cassette work on an 11-speed hub.Question
I want to purchase a Cervelo S5 frame and build my current Dura Ace 7900 gruppo onto it. However, I am not sure if my current Dura Ace crankset is compatible. Any idea? Another question, would a wheelset made for an 11-speed (thinking of the new / latest Dura Ace 11-speed) still work properly with an old 10-speed cassette? From: Andro
A simple delrin adaptor from Wheels Manufacturing is all you need to use a Dura Ace crank with a BBRight frame.
Answer
In this changing world we are all required to adapt but some adaptations are easier than others and this is one of those. Your Shimano crank will work fine. You just need this adaptor. The adaptors slide right into the bearings without any tools, making it really easy to set up.
11-speed wheels will work for you as well. You just need to use a 1.85mm spacer behind the cassette that comes with any 11-speed Shimano wheel. We have 11-speed Dura-Ace 9000 wheels in stock now: C24 Carbon Clincher & C24 Carbon Tubeless Clincher.
Let me know if you have any other questions.
