Bontrager Race X Lite Disc Tubeless review
Keith Bontrager’s still fanatical about his wheelset designs and this conventional-looking hoop is seriously light but still deep enough to be rockproof. The spoke eyelets are offset to reduce sideways dish and even out-spoke tension from side to side.
The relatively narrow width restricts fat tyre compatibility, but they come with an optional tubeless rim strip and valve. The super-skinny double-butted spokes do leave the wheel pretty flexy and twangy when charging hard or cornering, although we’ve never actually completely crisped a wheel.
The rebadged DT hubs keep the whole wheel extremely light too, and the ‘Star Ratchet’ freehub clutch engages quickly, giving a noticeable acceleration boost to already extremely agile wheels. Centrelock disc mounts mean you’ll need new rotors or an adaptor to run ISO rotors, but you do get particularly nice titanium skewers included for free.
