Full suspension Mountain Bike frames are becoming more popular with cross country riders due to the ability to keep power on over bumpy terrain (yes they are still massive with downhillers to). You will find that the wide tyres give you bags of grip and together with the front and rear suspension you will easily glide over trail detritus, roots and rocks. For the downhiller in you; A downhill bike (also known as a downhill mountain bike) is a full suspension bicycle designed for downhill cycling on particularly steep, rocky trails. Unlike a typical mountain bike, durability and stability are the most important design features, compared to lighter, more versatile cross-country bikes. Downhill bikes are primarily intended for high speed descent. So a full suspension bike offers both the downhill madness needed by the adrenaline junkies and the performance over rough terrain for the cross country riders.
