Specialized's ultimate M2 Metal Matrix frame has now been superseded by M4 - a unique alloy of aluminium reinforced with silicon, magnesium, vanadium and copper.
Almost twice the strength of 6061, M4 is also more malleable. This allows Specialized to optimise the shape and wall thickness of every tube to engineer a world class frame that's light (3.3lbs), strong, yet surprisingly supple.
The frame then comes fitted with stellar equipment such as the Judy SL fork (half a pound lighter than XC) and - very unusual this on a production bike - the pedals most frequently recommended in near every mag review: Time after time.
The M4 has been so well received in these parts, it has been bought by an unprecedented number of Edinburgh Bicycle workers in its first year of production -Linda, Henry, Grant, Mike and Paul - all of whom were owners of respectable mountain bikes. They're all stoked with their M4s. Grant's reaction was typical. 'I didn't realise it would make such a difference. My previous bike weighed 26lbs which is pretty respectable, but the M4 at 22lbs is night-and-day better. It climbs hills with so little effort.'
