gravel bike rim width Fulcrum Rapid Red 900 650B Road/Gravel Bike Rim – Clincher, 28H – Random Bike Parts

This is a brand-new Fulcrum Rapid Red 900 650B clincher rim, removed from a new wheelset and never built or used. Perfect for gravel and all-road wheel builds, this lightweight aluminum rim weighs just 510 g.

The asymmetric profile balances spoke tension, while the 22 mm inner width supports tires from 25 mm up to 64 mm. External width is 27.1 mm with a 24.1 mm rim depth, drilled for 28 spokes.

These are clincher rims — they can be set up tubeless with proper tape and valves but are not supplied tubeless-ready.
