Belfast, Ireland’s Nukeproof reintroduced the athlete-beloved Solum right before Crankworx Whistler, and aimed it squarely at pump track riders and brand devotees.
The dirt jump/pump track classic returns after a limited run in 2013 brought it notoriety, but not wide circulation. Now, it arrives almost a decade later with updates like a 6061 aluminum frame, clearance for up to 2.3” tires, and single-speed gearing that can accept a 32-tooth chainring.
Blurring the line between BMX and MTB, Nukeproof said the Solum’s comeback had “nothing to do with a new local pump track to the Nukeproof HQ.”
Just like the old build, it gets 26” wheels, usually the choice for dirt jumpers. Also like its predecessor, its geometry seeks to help riders dig into the rear wheel and pop up the front one.
The original Solum got a steel frame, but this year’s update gets triple-butted aluminum. Nukeproof said it made the decision primarily to cut frame weight, which is 4.76 lbs. (claimed). The brand also said the new Solum’s fully-forged yoke aims at maximum strength to weight ratio. And contoured seat stays help multi-directional stability during hard landings and firm pumps.
Factory gearing is 30-13, but you can upgrade to 32 in front and adjust to fit, thanks to the horizontal dropouts. The dropouts also let riders dial in their wheelbase (slam it tight for street or pumping, and spread it out for trail stability).
The Solum comes in two lengths. Both built around a 100mm travel fork, they seek to cater to specific riders’ heights and styles. Pump track riders might like the “regular” size better, because it should make manuals easier and allow faster direction changes.
The “long” frame may help dirt jumpers during rowdy landings.
If you want to see the new Nukeproof Solum shred before you’re sold, you’re in luck: the brand brought the bikes, a film crew, and Elliot Heap and Corey Watson to a session in Edinburgh.
The Solum starts at MSRP £500/$550.
