Front and rear travel are adjustable up to 6". Suspension design is single pivot but with the drive chain and pivot perfectly aligned the suspension is fully isolated from pedal induced feedback. Sliding rear dropouts mean that no chain tensioner is required. The in-house rear hub builds into a strong, light, un-dished wheel which can be removed leaving the disc, chain and rear cog attached to the bike. Production bikes will have a shield to protect the disc from the chain. The G-Box itself contains a specially adapted Rohloff hub and crank to give a fully sealed primary drive. In addition to the Enduro/FR version shown there will also be a longer travel DH bike.
