Swapping a suspension fork for this one takes more than four pounds off the very front of the bike — the single place where weight is most obvious, in how the front end lifts, how the bike accelerates, and how it feels at the top of every climb.\u003c\/p\u003e\n\n\u003chr class=\"fk-divider\"\u003e\n\n\u003ch4\u003eLight, and not harsh\u003c\/h4\u003e\n\n\u003cp\u003eThe usual objection to a rigid fork is that it beats you up. That's mostly true of aluminum ones. Carbon's advantage here isn't only mass — the layup damps high-frequency buzz, the fast, fine vibration from gravel and hardpack that makes your hands ache after two hours. You still feel the big hits. You stop feeling the constant chatter underneath them.\u003c\/p\u003e\n\n\u003cp\u003ePair it with a wide tire run at sensible pressure and you have a genuinely comfortable bike that weighs nothing and has no moving parts.\u003c\/p\u003e\n\n\u003chr class=\"fk-divider\"\u003e\n\n\u003ch4\u003eMounts for going places\u003c\/h4\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree cargo mounts per leg\u003c\/strong\u003e — anything-cages, dry bags, fuel bottles\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRack mounts\u003c\/strong\u003e — front rack or lowrider\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp class=\"note\"\u003eThis fork does not have fender mounts.

On a frame designed around a longer suspension fork, that height partly offsets the drop you get from this fork's shorter axle-to-crown — so a 32er build sits closer to the original geometry than a 29er build on the same fork does.\u003c\/p\u003e\n\n\u003cp class=\"note\"\u003e32-inch wheels, tires and rims are a young standard with limited availability.
