The Sturn V1 was a hell of a bike. Despite the internet's insistence that a single-speed, steel DH couldn't win races it went on to take the Masters European DH Champs and overall Masters Portuguese National Downhill Championship titles.

But, we were never quite satisfied that the bike was everything it could be. So we set to work on Sturn V2.

The Starling Cycles Sturn V2 is a revised, refined and redesigned approach to our race winner.

The BB and main pivot region have been completely redesigned, as well as a proprietary new Jack Shaft solution. The swingarm has been totally redesigned to be super neat and with reliable eccentric dropouts.

High pivots only work if you can control chain growth issues. An idler pulley is a decent solution, but the Jack Drive is the proper way to reduce friction, reduce chain forces and eliminate chain growth. Combine that with a super light, single speed rear wheel and you have suspension that feels absolutely sublime.

It tracks super rough terrain, it absorbs impacts beautifully and it carries speed like nothing you've ever ridden. Perfect chain line, a super light and strong rear wheel, super low maintenance and zero distractions.

We can do a geared version of the bike if you ask nicely, but single speed is where it's at. What if you had your best race run ever? Was it because you changed gear at the right time, or you could ride with total focus and flow, in total silence with nothing to take your mind off the trail?
