Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


An aggressive XC bike for riders that like the up, as much as the down, With a little less travel than the T-series, the Siskiu D-series are designed for fast and flowy XC riding. RockShox suspension front and back, and dialed in geometry keep you glued to the terrain. The 11-speed Shimano Deore drivetrain has enough mechanical advantage to take the edge off of the steepest climbs. And Shimano 2 piston brakes keep your speed under control in all conditions.
