What We Don’t Like

We haven't found any overwhelmingly negative opinions about the Synapse or any of its parts. If you are not a fan of disc brakes, these bikes are not for you. One bit of advice is to be careful with the brake and shifters. They are very quick to respond, and in some instances, haphazard braking could be unsafe.


  • Brakes can sometimes be too responsive if not careful
