Nukeproof Mega 290 Comp Bike

Since 1995, the infamous Megavalanche DH marathon race has been synonymous with big all-mountain riding. Starting at the highest point on Pic Blanc (3300m) above the village of Alpe D’Huez, it is seen as the pinnacle of mass start mountain bike racing around the world.

Originally conceived in 2009 as the perfect bike for this exact style of racing, the Nukeproof Mega was born. Now in its 4th evolution the Mega should need no introduction. It has tasted success within multiple disciplines and has numerous national and international race wins to its name.

Designed to excel on the toughest enduro tracks, the gravity focused Mega will inspire confidence on the most technical descents whilst maintaining pedalling efficiency for all-day epics in the saddle.

Brand new 29” Frame

For 2020 we decided to make some changes and bring the Mega 290 bang up to date. The 29” frame is finally available in two material options: Full alloy or Carbon fibre front triangle with an alloy rear triangle. Both options feature updated geometry, increased travel and a revised suspension kinematic.

Updated Geometry and Suspension

The brand new 29” frame uses a short offset 170mm fork paired with 160mm of rear travel to create a proper monster-truck of a bike. To accommodate these changes, we updated the geometry by slackening the head angle and steepening the seat angle versus the previous version. We also revised the suspension kinematic to make the bike as fast as possible; improving the small bump sensitivity, improved mid stroke support for more predictable cornering/pumping and increased end stroke progression to inspire confidence through the roughest terrain.

Tested and proven on the toughest of terrain and in the most varied conditions by Enduro World Series Winner Sam Hill, the 2020 Mega 290 sets out to tackle every ride with its trademark attitude.
