Depending on the use, it seems like gravel bikes are getting bigger tires all the time. Whether 650b or 700c,  volumes are growing and tread widths are increasing, which is good news for certain segments of the sport. It’s not so good news if you have a fork that doesn’t offer the same amount of tire clearance as the frame.

When Otso Cycles launched their Warakin gravel bike last year, it came with an excellent carbon fork, but it didn’t offer the amount of tire clearance they wanted for the bike. Over the past year or so, we’ve seen a number of sneak peeks in terms of Lithic Components on Otso builds, but we haven’t actually gotten the official word on the brand becoming available. That seems to change with the new Hiili carbon fork which should solve all of your tire clearance woes for the world of gravel…

 

 

Now the third brand under the Wolf Tooth Components roof, Lithic Components is described as a project of Otso to create very specific products for the cycling world. Those products naturally line up perfectly with Otso bikes like the Warakin gravel bike and Voytek fat bike to fill in gaps where the Otso team couldn’t source the right part from other vendors – because they don’t exist.

The Hiili fork looks to be that exact type of product with a rigid full carbon design that clears up to a massive 29 x 2.1″ tire with a 400mm axle to crown length. Sold in one offset at 47mm with a 1 1/8″ to 1 1/2″ tapered steerer, the fork features a 15mm thru axle, flat mount disc brake tab, and fender mounts on the inside of the legs above the brake caliper.

Specs:

  • 512g uncut
  • 15mm Through-axle
  • Flat-mount disc brake
  • Tapered steer tube, 1 1/8”-1 1/2″
  • Max Tire Clearance 29×2.1 (54-622)
  • 400mm axle to crown length
  • 47mm offset
  • Full hidden fender mounts

Moving forward as standard equipment for the Otso Warakin, anyone who already owns a Warakin can upgrade to the new fork for a reasonable $200. Otherwise the Lithic Hiili will sell for $490 and is available now. Otso is also adding new fork upgrade options to the Warakin builds with the Lauf Grit available at $350 and the Fox AX an additional $650.

That’s nice that they’re offering it to current owners so cheaply, but as an aftermarket fork it has less clearance, fewer mounts, worse cable routing, and is more expensive than a Rodeo Labs Spork.

Spork has less clearance.

They say it’s not for 2 inch tires but also claim 56mm of clearance, which is 2.2″

Clearance doesn’t = max tire size, it is the size of the opening. Anyone can decide how far they want to push clearance. In the dry conditions of Colorado a 48mm tire at 700c works great, but in muddy conditions that would be a horrible decision.

In a not to distant future, i see the second time re-invention of the standard approx. year 2008 MTB 29er hardtail. It will emerge as the perfect compromise. Righting all modern wrongs in one big swoop. Gears enough for flat/hilly/race/training and loaded touring. A wide versatile handlebar (but not a MX bar) A suspension fork with lockout.

Except that those old mountain bikes had slack angles, high BBs, long wheelbases and didn’t handle like road bikes. These are road bikes for trails. If you were a roadie you’d get it.

He said 2008 Hardtails not 1988. The 29er hardtail is essentially where all this gravel/adventure stuff is heading. If you were a mountain biker you’d get it.

If it had rack mounts I’d buy one, but no… 🙁
