Cannondale HollowGram R45 Disc Rear Wheel

Cannondale HollowGram R45 Disc Rear Wheel Whether used as a road or gravel wheel; Cannondale’s HollowGram R45 Disc Rear Wheel provides speed; reliability and performance. At 45mm deep the carbon rim helps reduce drag whilst the broad; blunt profile ensures that it isn’t unduly affected by crosswinds. The 32mm external width also adds excellent sidewall support for wide gravel tyres and creates a smoother junction between rubber and rim when used with a road tyre. As the rim is tubeless compatible; it easy to take advantage of the many benefits of not using an innertube. Tyre pressure can be lower without risking a pinch puncture; giving greater comfort; more grip and less rolling resistance. The hub features internals by Formula that offer 21 points of engagement for good pick-up when accelerating or overcoming an obstacle on the trail.
