ARMA Extreme Shox


With the changing world of the mountain bike and the increased use of the 275 wheel size, EXT & STENDEC have spent considerable time evaluating effects of damping frequencies that 275 produces against 26 inch.

As 275 smooths out the bigger holes that 26 falls into on the trail and DH course and the increased speed you ride at, this requires a finer tuned suspension with a bigger range of high frequency control, both the ARMA & STORIA are available in these tunes giving you an enhanced 275 ride.

Tuned for 27.5 incs and tuned 26 incs.
