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 trail as if it were an extension of your own body. Allowing you to be fast and efficient with an anti-gravity feel and laser-pointer precision. It begs you to climb more, go farther and descent anything you may encounter along the way. You're rewarded with free speed as every pump and pedal stroke propels you forwards while our sbg geometry makes sure you're composed for every root, rock or switchback. Don't judge a book by its cover through, with all these lightweight and uphill oriented character traits the spur require no adjustment to descent likely you're sued to; you might actually go faster.

Speed balanced geometry
sbg ensures the bike maintains low speed agility, front wheel traction and proper rider weight balance while actually increasing confidence in steep terrain and at high speeds. With sbg, a slacker head tube angle is combined with a reduced offset fork standard, preventing the front wheel from being too far in front of the rider. This improves front to rear weight distribution on the bike, which is often out of balance on long and slack bikes. One of sbg's greatest benefits is that it creates a confident steering feel that adapts to wheel speed. More stability when going fast, more agility on technical slow speed maneuvering as well as improved traction, control and confidence for any skill level of rider.

giddyup suspension design
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 37.5mm 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.
