The Chromag BA30 V2 is an aggressive alloy mountain bike rim built for riders who charge hard in rough terrain. A refined beadwall and sidewall deliver 20% more impact resistance than the original BA30, and a deeper rim section resists flat spots from hard hits, all with no increase in weight.
Each rim is extruded from 6069-T6 aluminum and joined with a full fusion weld that is ground smooth, a junction stronger than a sleeved joint and airtight for tubeless setups. A wide central channel makes mounting and removing tires easier, even trailside. This is the 32 hole drilling, and rims are sold individually.
