Meet the Bourne 29, an uncompromising cross country/marathon wheelset with wide rims of 24.5 mm (inner width). Why do you need wider rims? Well, it means more grip, more comfort, and lower rolling resistance.

The wide rims are made for tires from 2.1 up to 2.35 and allow the tires to adjust to their optimal shape. Especially when riding with low tire pressure the wide Bourne 29 rim supports your tire, preventing your tire from twisting or deforming in curves or steep climbs.

Valves & Disc Brakes

All 9th Wave tubeless wheels come standard with rim tape and lightweight aluminum valves installed. And, if you order disc brake rotors with your wheels, we will already mount these for you. All, so you can get out there and ride your new wheels as soon as possible!

Wheelsets with a Lefty front wheel will by default be made with a Cannondale Ai offset rear wheel. If you do not need Ai offset, please make a note when you place the order!
