The removable aluminium anti-shock frame holds the frame and wheels steady to prevent friction or compression damage. There is plenty of additional interior padding to protect your bike, minimum disassembly is required - only the wheels need to be removed. There is an anti compression disk included to reinforce the centre of the case. The 4 locks are flush fitting and it has 3 strengthened hinges. It is also designed for stacking, so particularly suitable for team use. Additional features on the case are 4 lifting handles, one folding pulling handle, which makes it easy to move around. It's suitable for all frame sizes, including full suspension mountain bikes. (Leave out the anti-shock frame and there's even room for downhill bikes!) There's plenty of room to stow other gear too.
