Transition Spur Carbon Frame, Powder Black

The All-Country Bike

Effortlessly explore, seek and pursue the mountain in ways you never imagined.

The Spur provides a sense of connection to the bike as if it were an extension to your body. Fast and efficient with an anti-gravity feel and laser-pointer precision the bike begs you to climb more, go farther, and descend anything you may encounter along the way. You’ll instantly appreciate the free speed you’re awarded while accelerating where you’re usually accustomed to pedalling. Don’t judge a book by its cover though, with all these lightweight and uphill oriented character traits the Spur requires no adjustment to descend like you’re used to, you might actually go faster.

GiddyUp Suspension
We want to make it as easy as possible to experience great rear suspension performance. The GiddyUp suspension system is designed to behave intuitively across a broad range of setup. Because, we get it, sometimes you just want to grab your bike and GiddyUp, without checking your setup. When you do, it will always feel good.

With nearly 30% of progression and a consistent linear rate of change, the Spur has an excellent balance of support and small bump sensitivity. Anti-squat is tuned to enhance pedaling performance and acceleration but doesn’t get in the way of the suspension working when it’s needed.

The GiddyUp suspension, featuring a one-piece flex stay rear triangle, is tuned to work correctly with inline style rear shocks and designed to provide a balanced feel with 120mm travel forks. Riders are able to add or remove volume spacers in the rear shock to suit their individual riding style and there is plenty of bottom out control for when things get rowdy. The Spur has 120mm of rear wheel travel when used with the supplied 190mm x 45mm stroke shock. It is also possible to install a shorter, 190mm x 40mm stroke shock, to reduce the rear wheel travel to 100mm if you are after a shorter travel experience.

A wide usable sag range of 25 – 35% allows the rider to tune the feel of the bike; from firm and snappy, to more supple and active. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp.
