Super light. Lightning fast. The Lauf Grit SL is the perfect addition to any gravel bike - or to “gravel-up” the CX bike. It makes the bike more capable and more comfortable. Make your next adventure the most fun one yet!
Zero Maintenance The design of the Lauf Grit SL is based around eliminating all “moving parts”, and therefore, friction and maintenance. The monocoque carbon fiber structure delivers incredible strength, and the test-fork we have in our lab has already been “shocked” over 1 million times, without showing any signs of wear and tear. That equals more grinding than you’ll manage to cram into at least 5 years of action!
S2 Springs The springs on the Lauf Grit SL are made of super strong S2 glassfiber that is extremely tough on hits and flexible in the direction of the travel. The springs have been “shocked” in our test lab over 1.500.000 times reaching 22mm amplitude every time.
Small Bump Performance The Grit SL is designed to maintain the lightness and reliability of rigid forks, while offering absorption and traction in small bumps that conventional suspension forks can’t match. The stiction and high unsprung weight of conventional suspension forks make them unable to keep up with high-speed input as brilliantly as the Lauf Grit SL.
Progressive Spring Rate The Grit SL has 30mm of travel with progressive spring rate. This means that the further the fork compresses the springs become stiffer. This helps keeping the fork from bottoming without sacrificing small bump compliance.
All Weather The Grit SL works flawlessly in all weather conditions. Whether you find yourself in the freezing Antarctica or the scorching Sahara - it also loves salt and sand. Grab your rig and just ride!
Cargo Mounts We do not have cargo mounts on our forks but there are 3rd party solutions that can be used. For instance the Twofish Unlimited Quick Cage adapters that can be used with a broad variety of cages.
Wheels 700c and 27.5" We recommend 700c for less rolling resistance.
Max Tire Width 700x45mm or 27.5x2.1" The Grit SL forks can take up a whole lot of rubber, which can save your day when things get dirty.
Travel 30mm This is the sweet spot for our forks. Since the travel is fairly short and progressive, we don’t need damping. That makes the fork a lot simpler and maintenance free.
Weight 850 g The Grit SL is super light and the perfect addition to gravel bikes - or to "gravel-up" cyclocross bikes. Weight measured with 210mm steerer and Lauf axle.
Unsprung Weight 250g The low unsprung weight is one of the design elements that makes this fork extremely good at tracking small bumps and chatter which gives you great traction and isolates you from vibration.
Axle 12mm or 15mm thru-axle All forks are supplied with our own Lauf axle. A lightweight low profile axle, which requires a 6mm allen key. If you prefer a lever, you can replace the 15mm Grit SL with e.g. the RockShox Maxle.
Hub Spacing 100mm
Rake 47mm The rake on the Grit SL is made to fit the slightly longer axle to crown then on on most gravel forks, while maintaining steering characteristics of 45mm rake rigid fork.
Axle to Crown 409mm (with 6mm sag) The axle to crown on the Grit SL is slightly longer then on most rigid gravel forks, which is necessary to incorporate the 30mm travel. Combined with the 47mm rake the Grit maintains the steering characteristics of a rigid fork with 45mm rake and 395mm axle to crown. Steerer Tapered 1 1/8" - 1 1/2" The Grit SL has an integrated crown race with 45° angle. It comes with a bearing that fits most headsets (45° upper and lower) but please check if the bearing fits your current headset. Uncut steerer is 300mm.
Minimum Rotor Size 160mm The Grit SL is made for flat mount brakes. Spacers can be used to fit a 180mm rotor. If you'd like to use post mount brakes you should use this adapter for 160mm rotor: SM-MA-F140PDA.
Rider Weight Limit 110 kg This is your weight including gear.
