Mega AM 275

“Go places, Win races”

Born on the infamous Alp D’huez mountains, the Mega AM has grown and matured alongside the racers and evolved into the ultimate ‘do it all’ race bike. At home on today’s Enduro World Series and thriving in events such as the Megavalanche and Mountain of Hell where performance and reliability are a key factor among race winners.

Custom hydroformed frame with Erosion Linkage suspension

The Mega AM Pro frameset is engineered from custom hydroformed double-welded T6 6061 aluminium, with our Nukeproof ‘Erosion’ linkage giving a smooth progressive suspension action with a well controlled mid-stroke to avoid wallowing under pedal loads.

Oversize main pivot bearings stradle 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 steep 73.5deg seat angle, with a long wheelbase keeping the centre of gravity low for optimum stability at speed.
