Bill Shook’s award winning tubeless cross country rim system has proved to be a magical combination of light weight as well as strength, stiffness and control. The tubeless rim is light and at 26mm wide x 23mm deep. It is wider, stiffer and supports the tire better for improved ground control. This translates into quick acceleration, more speed over rolling hills and mountain goat climbing. The wide rim keeps the tire from rolling around resulting in more control while descending. Bead barb technology hooks on the tire bead to help keep the tire in place without burping. Driven by vision and created by hard work, Bill Shook brings innovation to reality to boost your performance racing and training.Can be ridden with regular tire and tube.DISCIPLINEMTB Cross CountryRIMSMTB Tubeless Aluminum Disc Rims 26" | 29"SPOKESAC 14/15 Gauge Spokes Black | AC Aluminum nipples Silver | 32h 3-Cross Front and RearWEIGHT26: Front 691gr | Rear 795gr | Pair 1486grWEIGHT29: Front 748gr | Rear 852gr | Pair 1600grHUB/SPACINGFront Disc 130 100mm | 15mm Thru Axle Disc 100mm Lefty Disc 100mm | 9mm Thru Axle Disc 100mm Rear Disc 225 135mm | 10mm x 135mm Thru Axle Disc All Mountain Disc Thru Axle 12mm x 135mm 142mm Thru Axle DiscRear Spline Shimano/Sram 9/10 Sram XX1LOOK/COLOURAC Cloud Black with Grey HubsINCLUDEDAC MTB Tubeless Tape Installed | AC Tubeless ValvesQUICK RELEASECromoly QR’sUPGRADESCeramic Bearings | Titanium QR’s | Wheel Bag | Thru Axle QR’sBRAKE INTERFACE6 Bolt International Standard
