When getting up hills matters as much as getting down them in one piece we outfit the Rockshox SID SL Select 29in Boost Fork to our prime time ready cross-country machines. Featuring 100mm of travel with the new charger damper this fork handles the rough and tumble of cross-country racing without a second thought. Rockshox improved the chassis for stiffness and the new SID Sl features a full aluminum design that adds strength and stability to any riding situation.
