What is a Hard Tail Mountain Bike?
Thick, knobbly tyres and lots of gears are the overriding features of these machines. Strong frames are built to take the rough with the smooth and can often be accompanied by a front suspension fork for added comfort and control. Theyre designed mainly for off road use but these solid, comfortable bikes often meet more general needs. For further information on mountain bikes see our Mountain Bike Buying Guide.
