The Solum has long been a favourite among riders looking for a dialled 26” dirt-jump and pump-track weapon. The Nukeproof Solum blends the simplicity of a single-speed setup with the refined details riders demand. Constructed from custom hydroformed 6061 triple-butted tubing, the Solum delivers a lightweight yet incredibly strong chassis. Stiffness is engineered precisely where it’s needed to maximise power transfer when pumping. A fully forged yoke optimises strength-to-weight and provides generous chainring and tyre clearance (up to 2.3”). Nukeproof recommends using 30t–13t gearing, but there is room to run up to a 32t chainring for use at BMX tracks where speed is the key. Wave-shaped seat stays and a reinforced brace add multi-directional strength for riders who love to throw tricks. Despite being built to take the hits, the frame still comes in at a respectable 2.26 kg / 4.76 lb (regular). Available in three sizes that are all optimised around a 100mm travel fork: Regular, Long and Extra Long; the Solum is available in a size to fit all heights and riding styles. Dialled rear dropouts allow you to fine-tune chain tension and adjust the wheelbase: slammed for street and pump-track riding, or extended for trail stability. The new Solum is built for one thing: pure, unapologetic fun. Ready for the playground.
