The New Lithic by Wolf Tooth Carbon Mountain Fork May Be the Most Versatile Rigid Fork

When it comes to installing a new fork on your bike, there are a lot of standards to consider. Wouldn't it be nice if you could just buy one fork that would cover most of them? That seems to be the thought with the new Carbon Mountain Fork from Lithic by Wolf Tooth.

Back in 2016, when Otso Bicycles grew from Wolf Tooth Components, we were introduced to a new component brand, Lithic. At the time, Lithic was mostly an OEM house brand for Otso to spec their bikes with various components, Lithic has slowly grown into a brand of its own. Now, Wolf Tooth is calling it ‘Lithic by Wolf Tooth’, likely for the brand recognition, but the goal remains the same – to create high-quality components that often include details not found elsewhere.

Take their new Mountain Fork for example. On the surface, it’s a rigid carbon MTB fork, but as soon as you start digging into the details you realize that this fork may be the most versatile on the market.

Thanks to four different droput options, the fork will fit 15 x 110mm Boost hubs or 15 x 100mm non-Boost hubs, both with post mount or flat mount brake options. From there, the dropout flip chip can be used to adjust the offset/rake from 44mm to 51.5mm. Better still, flilpping the dropout chip still preserves your brake adjustment.

Suspension corrected for 120mm travel forks, the Mountain Fork has a 495mm axle-to-crown with the 44mm offset, or 498mm A2C with the 51.5mm offset. Offereing tire clearance up to 29 x 3.0″, the fork is only offered with a 1 1/8- 1 1/2″ tapered steerer. External brake routing makes it a cinch to swap between your rigid fork and a suspension fork when needed, and the three-pack mounts on each fork leg make it perfect for bikepacking duties.

Lithic Carbon Gravel Fork & Fat Fork

Unlike the Mountain Fork, the Lithic Carbon Gravel Fork and Fat Fork (below) have been avaialble for some time as original equipment on Otso bikes. Both have fixed offset numbers, brake standards, and hub widths, but still offer a rigid carbon option for those that need it.
