The single best way of tuning your bikes handling is by changing the forks. Rigid forks provide the ultimate in rider feedback but at the expense of comfort. Most MTBs now use suspension forks but it's vital to fit the right ones. Cross-country suspension forks offer the best combination of comfort, control and weight. They can be used on hard-tail or full-suspension frames. Models with either manual or automatic lockout will save energy compared to ones that are always active. Long travel forks are designed for riding extreme terrain, usually in tandem with rear suspension.
