Now in its twenty seventh year, the Rockshox BoXXer gets a new twin-tube air spring and truly separate compression adjustment.
Rockshox stick with the two fork line up with the BoXXer Ultimate staying as king of the hill, and the BoXXer Base replacing the BoXXer Select.
Whilst the Rockshox BoXXer retains its 38mm chassis, the rest of the dual crown fork has been redesigned, mainly to provide a better balance between stiffness and dare we say it, flex. Yes, brands are now realising that making things stiffer every year isn’t actually all that good for the human piloting the bike down a hill.
Beyond the reingineered upper and lower legs, the Debonair+ air spring is all new, featuring a twin-tube air spring. A hollow 14mm shaft replaces the older 10mm offering which increases the negative air spring volume. The end result of the new air spring is a more linear spring rate, tunable through the usual pressure and Bottomless tokens.
On the new uppers, there’s oil flow ports located near its bottom. These openings circulate more lube through the bushings. They’ve the added benefit when the fork is going through its travel the new design aims to evenly distribute air volume above the lower bushing, resulting in a consistent spring rate for a more consistent ride.
Buttercups and the RC3 damper introduced on the Pike, Lyrik and Zeb, now make their way into the BoXXer platform. The RC3 damper has been tweaked to better separate the high and low speed compression circuits.
The BoXXer Ultimate is the only fork that will be available aftermarket, with the BoXXer Base coming as OE (Original Equipment) on complete bikes. The BoXXer Ultimate comes in at ÂŁ2,029.00 RRP.
