Nukeproof Digger 275 Comp 2021 - Gravel Bike

What started during an intoxicated conversation some years ago, has ended up as a cult product in our range.
Inspired by our athletes and their desire for a do-it-all training bike with something a little extra; it’s a versatile vessel, blending “gravel bike” performance with the soul of a mountain bike. With the capacity to add panniers, bike packs and mud guards; the Digger frame is suited for everything from big adventures in the wilderness to a bike that simply makes the usual mundane commute to work more interesting.
New for 2020 is the addition of the latest gravel dedicated Shimano GRX 1x group set. Spec’d for simplicity and off-road performance with Shimano’s clutch derailleur 1x 11 speed set up (11-42t) drivetrain. The Digger is again equipped with a “wider than average” drop handle bar for that mountain bike stance.
Both 2020 Comp and Factory models will come with WTB Sendero’s 650b Road Plus tyres. To add comfort to the ride the Digger features a bolt through carbon tapered fork and cork-gel bar tape for compliance and improved feel on the trails/ gravel/ paths/ road.
The Digger yearns to divert you off the main path and create an adventure of any ride.
