A double-butted 4130 chromoly rigid fork with more places to bolt gear than any fork we make — five cargo mounts per leg, plus fender and rack mounts. Nothing to service, nothing to charge, nothing that can lose its damping two days into a tour. What it's actually for A suspension fork is the right answer when the ground is steep, rough and technical. Everywhere else it's 5 lb 12 oz of moving parts you're carrying up every climb, and a service interval you keep meaning to get to. This is the other answer. Steel takes abuse and shrugs off the scratch that would have you wincing at a carbon leg. It's the cheapest of the three forks to replace if you ever destroy one. And with mounting bosses up and down both legs, it turns a hardtail into something you can actually load up and disappear on for a few days. Dirt roads, doubletrack, bikepacking routes, hardpack singletrack, and the commute in between. That's the brief. Mounts everywhere Five cargo mounts per leg — the most of any fork we build. Run anything-cages, dry bags, fuel bottles, or a mix, and still have bosses left over. Fender mounts — proper ones, so you're not zip-tying a mudguard to a brake hose in February. Rack mounts — front rack, porteur tray, lowrider panniers. This is the part a suspension fork can't do at any price. Stanchions and lowers have nowhere to put a bolt, which is why every loaded touring bike you've ever admired is rigid up front. Fitment — read this before you buy This fork has a straight 1-1/8" steerer, not a tapered one. It ships with a 30mm cone that lets it run in a tapered head tube — which includes the 4130 Trail and most modern mountain bikes — so you don't need a reducer headset. Check what your frame uses before ordering, and talk to your shop if you're unsure. Everything else is current mountain bike standard: 15 x 110mm Boost front hub spacing, thru-axle included Post mount brake, 160mm native — a 180mm adaptor is included in the box, and 203mm works with the appropriate adaptor 300mm steerer, shipped uncut so your fitter sets your stack height, not us 29" wheels up to 3.0" of tire If you're fitting this to a 4130 Trail Worth knowing what changes. The RockShox Psylo Silver RC that ships on the 4130 Trail measures 550mm axle-to-crown . This fork is 492mm — 58mm shorter. Dropping the front end that much steepens the head angle, lowers the bottom bracket and shortens the wheelbase. The bike gets quicker-steering and sits lower. That is the intended result, not a side effect: you're converting a slack trail hardtail into a fast all-terrain bike. But it is a real change in character, so go in expecting a different bike rather than the same one minus the squish. You'll also save 1 lb 12 oz over the suspension fork.

The carbon rigid fork weighs 563 grams — two and a half pounds less than this one — with a tapered steerer and three cargo mounts per leg. See the carbon rigid fork ? Buying a complete bike? The 4130 Trail is available built around this fork from the factory, which costs less than buying the bike and the fork separately. See the 4130 Trail ? ?? Professional installation recommended. Fitting a fork means cutting a steerer tube, setting a crown race, and adjusting headset preload — all of which affect whether the bike steers safely. The steerer ships uncut on purpose. If you're not set up to do this properly, have a shop do it. Want to get technical? Full Geo / Specs here .
