A new enduro bike with a (sort of) new suspension platform from the Canadian brand.

Rocky Mountain Bikes revives their LC2R suspension linkage for the 2024 Altitude enduro bike, plus give it a reach adjust headset.
Apr 2024
Today Rocky Mountain debuts the newest Altitude, a completely redesigned 160mm travel enduro bike intended to win an EWS championship or make your friends feel slow on their favourite trail. Upon first glance, purists would say this looks nothing like a Rocky Mountain, as the Low Centre Counter Rotating platform, AKA LC2R, replaces the 4-bar Smoothlink suspension design. Old Man Mountain Bike would recall Rocky using the LC2R platform on mid-2000s Slayer and Flatline models, shelved until now. Strands of LC2R DNA floating in the aether of Rocky Mountain’s Development Center in North Vancouver are reconceptualized as a tool worthy of surpassing the previous Altitude in every facet. This is no small feat, as Jesse Melamed, ALN, and Remi Gauvin all stood on EWS/EDR podiums aboard the previous Altitude, so what kind of changes are we talking about? Well, nearly everything…

When we think of Rally, images of sideways Subarus and Dakar 450's come to mind. Vehicles capable of haulin' arse over gnarly terrain all while looking so damn good in the process. It's an aesthetic that has made its way into the Rocky Mountain range of bikes over the years and 2024 ain't no different. We take a deep dive into Rocky Mountains new Altitude C90 Rally edition to see if it lives up to it's namesake. Review: Blake Nielsen [...]

The Rocky Mountain Altitude C90 enters the “Best Enduro Bike of 2022” group test as the defending champion. But can it claim victory for the second year in a row and convince our test crew with its all-round qualities and smart details?
Adjustable chainstay length has pronounced effect on handling
Excellent suspension
Superb all-round qualities on all trails
Long seat tube and short insertion depth
No storage compartment or tool strap mounts

Rocky Mountain’s Altitude Powerplay can keep up with aggressive riders wanting to push hard yet is equally at home cruising trails under riders who just want to explore and have fun.
