the Cale AL
An expedition-ready hardtail
"With raucous off-road ability and a Sherpa-like carrying capacity, it’s ready for expeditions in the high mountains."
Introducing the Cale AL
An aluminium sibling for our most trail-capable bike. A few tweaks and a new lightweight aluminium frame see the latest Cale AL ready to take on any track. With raucous off-road ability and a Sherpa-like carrying capacity, it’s ready for expeditions in the high mountains. Equally at home smashing around your local trail centre, it comes with fast-rolling 29-inch wheels, but will also work with oversize 27.5+ tyres. Equipped with a dropper post and tough suspension fork, it’s mountain-ready out of the box.

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.
