With its silver finish M4 frame, the Stumpjumper looks as light and bright as it rides.
- M4 is Specializeds unique alloy of aluminium reinforced with silicon, copper, magnesium and vanadium.
- 24% stronger and more formable than 6061 aluminium, M4 can be thin-walled without compromising strength.
- £489-worth of Fox 80RL forx - tracks like a laser, stout as a lighthouse, smooth as Lurpak.
