We’d Like You to Meet: The 2015 Rocky Mountain Thunderbolt MSL
Developing bikes out of their facility at the base of British Columbia’s North Shore mountain since 1981, Rocky Mountain has announced the release of their next big thing: the 2015 Thunderbolt MSL
From Rocky Mountain:
Named after its lightning quick agility, the 2015 Thunderbolt MSL dominates on a variety of terrain. Equally at home on long, technical climbs as it is flowy singletrack descents, it’ll have you powering through the rough stuff and popping off every trail feature you lay eyes on. The all-new SMOOTHWALL™ carbon frame on Thunderbolt MSL models represents a major milestone for Rocky Mountain: by using our new PIPELOCK™ main pivot we have removed all traditional bearings from the frame. This combined with grease ports in key pivot locations results in a stiffer, lighter, and lower-maintenance bike.
THE RIDER
We designed the Thunderbolt MSL for our own special blend of XC and trail riders—people who hammer at the pointy end of the pack, but stay aggressive and stylish when terrain gets rougher. Marathon racing? Sure. Triple up those whoops? Why not! BC Bike Race? Of course! Smash every corner? Be rude not to.
THUNDERBOLT MSL RTC DESIGN
We gave the Thunderbolt MSL 120mm of SMOOTHLINK™ suspension travel to provide a perfect blend of XC efficiency and trail capability.
In order to achieve the agility and responsiveness we were looking for with this bike we chose 27.5” wheels and engineered short, 422mm chainstays. We increased control by lengthening the toptube and reined in the stem length, and were able to significantly reduce standover height by tucking the shock into the toptube.
Finally, we added our RIDE-9™ system into the mix, providing a wide range of adjustment—from slack and progressive to steep and efficient—to allow riders to dial the Thunderbolt MSL in for their preferred riding style and terrain.



THUNDERBOLT MSL BC EDITION
We’re a selfish bunch, so we couldn’t resist producing a Thunderbolt MSL BC Edition. With its lively, bottomless-feeling SMOOTHLINK™ suspension curve, adjustable RIDE-9™ system, and class-leading stiffness it was the perfect candidate for some additional brawn. Set up the way we set our own bikes up—wide bars, short stem, big tires, stiff wheels, and premium suspension—, the BC Edition translates the Thunderbolt’s agility into true trail bike playfulness and aggression.
