Nukeproof Mega AM 275 - RockShox Monarch

Mega AM 275 - all-mountain, all the time

The 2013 Nukeproof Mega AM was an evolution of our Megavalanche inspired Enduro race machine.

For 2014 we’ve tweaked the geometry and optimised it for the new 27.5” wheel size, offering a more stable platform and improved rolling over rough and technical terrain.

Now designed to take forks with up to 180mm travel, the Mega AM 275 combines downhill prowess with pedalling efficiency - perfect for the unique challenges thrown up by competitive Enduro events, Alpine trips, All-Mountain adventures or tough, technical riding where uplifts aren’t an option.

Progressive suspension

Suspension-wise, the Mega uses our 'Erosion' linkage giving a smooth progressive action with a well controlled mid-stroke to avoid wallowing under pedal loads.

Oversize main pivot bearings are contained in a bespoke CNC-machined Bottom Bracket assembly to ensure alignment, durability and precision, while an asymmetric chainstay design gives clearance for a front derailleur and compatibility with all leading models of ISCG 05 - mounted chain retention systems.

Geometry is based around a slack 66deg head angle and 73.5deg seat angle, with a long wheelbase keeping the centre of gravity low for optimum stability at speed.

A 44mm headset standard keeps the front of the bike light, with Nukeproof headset options allowing flush internal, flush top/external bottom, tapered or 1.5in headset compatibility, while at the rear, a 142mm x 12mm thru-axle keeps things planted.

The Mega AM also features removable cable guides for a ‘gravity dropper’ adjustable seat post, as well as internal cable routing for a RockShox Reverb Stealth post.
