The Lauf Grit is the perfect addition to any gravel bike or to “gravel-up” the CX bike.View Specs
The Lauf Grit is packed with features that make a world of difference on gravel. Become smoother, faster and enjoy the gravel miles to the fullest.
700c and 27.5"
We recommend 700c for less rolling resistance.
700x42mm or 27.5x2.1"
The Grit forks can take up a whole lot of rubber, which can save your day when things get dirty.
30mm / 1.18"
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.
900 g / 1.98 lbs
The Grit forks are very light and the perfect fit on gravel bikes - and to "gravel-up" cyclocross bikes. Weight measured with 210mm steerer and Lauf axle.
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.
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 it on the 15mm version with e.g. the RockShox Maxle.
The rake on the Grit 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.
409mm (with 6mm sag)
The axle to crown on the Grit 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.
Tapered 1 1/8" - 1 1/4" (supplied with a crownrace to fit 1 1/2" lower)
The Grit comes with a crown race for 1 1/2” lower bearing should that be necessary. If you have a 1 3/8” lower bearing (Specialized) you can purchase an adapter in our online store here. Uncut steerer is 300mm.
The Grit forks are 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.
110 kg / 242 lbs
This is your weight including gear.
In most cases the fork will fit your bike if it's new-ish. There are a few key parameters that need to be checked to quickly assess if the fork fits - you may need to confirm the fit with your bike manufacturer.
- Headtube needs to be tapered:
1 1/8" to 1 1/4" (or 1 1/2" if you use our included crown race adapter for that).
- If you have an oversized (44mm/1 ⅛) headtube you can use a cup.
- Front hub needs to take 12mm or 15mm thru-axle. Depending on the fork you want.
- The hub needs to 100mm wide.
- Brakes should be flat-mount (unless you have an adapter fro post-mount).
- The head set bearings to go with the fork need to have a 45° angle, top and bottom.
- Rotors should be 160mm.
No, you can't. But please read further.
On a conventional XC suspension fork you definitely need lockout. You need it because there is a substantial energy loss in the suspension movement (i.e. friction and damping mechanism), therefore you want to block all suspension when you don’t desperately need it. Hence, high end conventional XC suspension forks should be lockable. This however puts you in the position of constantly evaluating if you should prefer suspension or energy efficiency. In many cases you end up carrying a hugely overweight “rigid fork” over the majority of a race. This is particularly true for most XC-Marathon races. A Lauf fork on the other hand doesn’t have friction or a damping mechanism. Making it energy efficient by the nature of its design, so it shouldn’t be lockable. This way it can filter out all those small bumps you frequently encounter, without wasting your energy! To keep the suspension from feeling bouncy we set the spring rate of Lauf forks fairly high (hence only 60mm of travel are needed) so in most cases you won’t even notice that it’s moving at all. You’ll just notice how the road smoothens.
We highly recommend giving your fork a hot bath from time to time and gently get rid of all grime. It's so much more fun heading out on a clean fork - plus we've heard that clean bikes are fast bikes and clean forks are happy forks.
The difference is small but huge. The biggest change you'll see is the appearance. The Grit SL looks more straight.
Other stuff the Grit SL has over the Grit:
- 50g lighter.
- Laterally stiffer structure.
- Stiffer structure fore/aft.
- An integrated crownrace.
Yes you can. Just make sure you purchase an axle with the correct measurements.
Full length 148mm (for hub width 100mm) with 12mm or 15mm diameter axle depending on the model you have. Thread pitch 1.5mm
