An all-out XC bike requires an all-out XC fork to match its performance. By their very nature, cross country bikes are designed to be light and fast, but with race courses becoming more technically challenging, they need a suspension fork that can cope with these demands. Enter the Rockshox SID. Ultra lightweight and performance driven, the RockShox SID is perfectly suited to the rigours of cross country racing and is now available with up to 120mm of suspension travel to deal with any rock garden a race throws at them. These forks are designed around a 29" wheel size and as with other forks in their range, the RockShox SID can be used on an e-bike as well.
