CALE
A long, stable, steel hardtail, the Cale’s tidy rear end means it can saunter through surface resistance while remaining comfortable on long outings. Inspired by the success of its Beyond+ cousins but equipped with a RockShox Pike fork, expansive bar and short stem, the Cale will feel more than capable over any terrain. On the descents, flick the KS E20i dropper seat post, and on the way back up, take your pick from a cog from the 10 – 52T cassette powered by the Sram GX Eagle 3.0 12-speed groupset. With the Cale, one thing’s for sure – you’re going to have buckets of fun.
Triple cage mounts plus the ability to fit a rear rack mean it’s possible to ride into remote locations, drop the bags, and have some fun exploring new trails.

¹ Our bike size recommendation generally represents a rough guideline for quickly narrowing down the sizes from which to choose based on the body height. Bike fitting is a complex topic and other measurements and factors have to be accounted for as well. Since no two human bodys are exactly the same it is not possible to give a 100% correct advice for everyone. Therefore BOMBTRACK cannot guarantee for the stated recommendations to be correct for every individual customer. The best way to work out the correct size is to consult a local BOMBTRACK dealer or a professional bike fitter and have them determine the needed size.
