With a long history of going big, the Rockshox Domain has received a makeover and is now an even more formidable force in the long-travel single-crown arena.
With a new burly 38mm chassis, borrowed heavily from the hugely successful ZEB forks, The B1 Domain is even stiffer and stronger than before but remains reasonable in the weight stakes, at a smidge over 2.5kg (not bad for a 180mm fork!). It uses 6000 series aluminium stanchions and the familiar magnesium alloy lowers, with a forged alloy crown and aluminium steerer tube.
The Debonair air-spring is both plush and supple and can be tuned with volume tokens to provide even more progression for big hits, and the Motion Control damping is simple and effective with adjustable low-speed compression with an override blow-off valve and utilizes Maxima Plush suspension fluids from the factory for reduced friction and wear and consistent suspension feel in all conditions.
The Domain RC B1 is E-MTB approved and will fit tyres up to 2.8, rotors up to 200mm and is available in 15 x 110mm Boost spacing exclusively for both 27.5 and 29 wheel sizes.
