Two teammates asked me to help them upgrade their bikes from 10- to 11-speed recently. They knew how to do most of the mechanical work but they were concerned that their rear wheel wouldn’t handle the 11-speed cassette, in effect making it impossible to upgrade. They’re not the only ones who’ve asked about this, which makes it a trending topic, to use social media speak. I thought I’d share how I helped them with this key part of the upgrade in case new 11-speed components are on your wish list. And, because it’s usually something you can handle yourself.
