Crankbrothers fixed my mistake. I

"Crankbrothers fixed my mistake. I ordered the correct product but they actually recommended the steel version instead of the alloy version because I have an E Bike. So they took care of the exchange no problem! I also called for tech support when installing the new freehub body. I went from shimano to sram and they gave me strp by step instructions on how to swap everything. Love Crankbrothers. Good team all around!"

Q&A

I have the synthesis enduro alloy wheels with CB hubs. If I want to run a different drivetrain all I have to do is buy the proper freehub and swap it out? Id like to move from HG to MS.
Hi Ian, Thanks for your questions. That is correct, all that is needed to change drivetrain cassette compatibility is a new driver body for your rear hub. We offer Synthesis CB Hub driver bodies thru our website (linked below). https://www.crankbrothers.com/collections/synthesis-accessories-1/products/synthesis-freehub-body?variant=39654956302432 The alloy or steel option will work for you. Steel is heavier yet stronger, and usually recommended for E-Mtb's, but there's no reason you can't use it on a non E-Mtb. Cheers, Crankbros Rider Support
Hello, is the i9 xD driver compatible with crankbrothers hub ? If not. How can I add more pawls to my current crankbrothers hub for quicker engagement.
Hi Nestor, thanks for your question. The I9 XD Driver is not compatible with the Crankrothers hub. Regrettably there is no way to add pawls and increase the hub's engagement.
