Frame: Mega AM

 

Description

Mega AM – all-mountain, all the time

The original Nukeproof Mega was inspired by the explosion in Enduro-style DH events, taking its name and its cues from the daddy of them all – the Megavalanche

For 2013 we’ve given the Mega AM a makeover, with an all-new custom hydroformed tubeset for increased front-end stiffness and improved strength-to-weight ratio, plus an additional 10mm rear travel – now 160mm – offering ultimate stability and confidence on the most gnarly of Alpine descents.

Now designed to take forks with up to 180mm travel, the Mega AM 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 72deg 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.
