The flat-sided Syncros RR1.0 wheels look old-school at first, and we were expecting stubborn handling at speed and in crosswinds, but the 22mm-wide rims actually steer remarkably well.
The broader tyre base gives enhanced traction and a smoother ride than with standard-width wheels, and there’s no trace of warp or vagueness through corners or softness when you stand up and give them full gas.
While the DT freehub can take a while to engage, very low weight (669g front, 801g rear) means a serious leap in speed once they’re locked in and they flatter fitness even on seriously steep climbs.
They can also ‘feel’ faster in calm conditions than the Zipps and other fatties. The Syncros wheels are undeniable surprise performers.
