RockShox BoXXer C1 2019

The C1 Boxxer uses a similar 35 mm chassis of the previous A1-B2 versions but with changed cap threads, air springs and dampers.  29" wheel is an option now and brake/axle spacing is boost which is still 110 x 20 mm but puts the brake rotor and caliper 5 mm further left.

All models use Debonair air spring with a notch in the stanchion to balance positive/negative.  The base model RC has the self bleeding RC damper, the WC has the Charger 2.0 RC2 damper.
