Cairn Cycles announced the Adventure Gravel Fork, a carbon fiber unit that packs versatility and big tire clearance. Said to fit 700x45mm or 650bx2.25″ rubber, it also features Dynamo cable routing, fender compatibility, and ‘anything’ cage mounts for your next overnighter.

Cairn Cycles Adventure Gravel Fork, the ultimate gravel fork?

Gravel and adventure products continue to grow as a category, and the Adventure Gravel Fork from Cairn Cycles was built with the aim to be the ‘Ultimate Gravel Fork’. It was created in conjunction with the E-Adventure 1.0 bike, but Cairn says that it’s suited for any gravel bike that needs more capability to explore.

The tire clearance, while not industry-leading, is generous at 700 x 45mm or 650b x 2.25″. However, if your trails require more rubber than that, you’re probably better off on a mountain bike.

Internal Dynamo cable routing allows for lights or USB charging ports, while brake hose routing runs through the left fork leg.

There are mounts galore, for fenders and versatile ‘anything’ cages.

Cairn specs a 12mm front thru axle, flat mount brakes, and even an integrated bottle opener in the axle lever. Full specs are below:

  • Axle to Crown – 395mm
  • Flat Mount – 70mm
  • Steerer length – 300mm
  • Steerer Tube – 1 1/8″ to 1 1/2″ Tapered
  • Steerer Diameter – 28.6 mm
  • Thru Axle – 12mm x 1.5mm thread pitch
  • Brake Hose Hole Size – 8mm
  • Axle Spacing – 100mm
  • Weight – 522 grams
  • Fork Offset – 48mm

The Adventure Gravel Fork is available for pre-order now, for £209 / $273 / 246€. Product deliveries are expected in March 2020.

Why do the specs say the fork offset is 48mm, when the photo says 55mm? I checked, and the same conflicting numbers are on their website, too. Otherwise, this would have been a perfect replacement for the damaged fork on my Jamis Renegade (53mm offset), but I finally found a replacement.

It also says axle to crown is 425… which isn’t even close to the advertised spec.

You are right, its is conflicting information. Images were taken of a sample fork which did have different geo. The text spec is correct geo for the fork though.

55mm rake would be better than 48mm for the bikes we’re building, but what’s with the steerer? Is that an integrated bearing seat? I mean, I understand the structural advantage of that, but it severely limits the headset options. Not necessarily the best move for an aftermarket/3rd-party fork. Also, why is internal brake routing on an “adventure bike” fork considered a plus? Aerodynamics?

Internal routing because it looks better. I know you weren’t born yesterday.

I’d like to see these with boost spacing to help keep down the number of wheels I “need”
