Climbing, descending and tackling technical terrain with confidence, the Salsa Horsethief SLX 29 is the one-bike-quiver that's ready for all the trails on your bucket list.

  • Features

    • Durable, high performance Shimano SLX drivetrain components provide silky smooth shifting that'll keep you covering ground and pouring on the miles
    • Progressive trail geometry gives you more room to move front to back, and it puts you in a better position to tackle technical terrain
    • Modern trail bike fit uses a short stem, wide bar and longer effective top tube to get you into the same familiar position as on your older trail bike
    • With 140mm front and 120mm rear suspension, this bike is ready to tackle all the trails on your bucket list
    • RockShox® Recon RL 140mm offers proven performance with a Motion Control™ damper
    • 120mm travel Split Pivot® rear suspension is controlled by a RockShox Deluxe RT shock, which is super supple, reactive and easily tunable
    • Split Pivot features a pivot in line with the rear axle that isolates pedaling and braking forces for more traction and control when climbing, descending or cornering
    • Metric shock standard requires lower air pressures, resulting in increased stiffness in rear triangle/rear suspension frame members and the ability to fine-tune ride quality
    • Horsethief can run 29er or 27.5 wheels thanks to Flip Chip technology; max tire width is 29 x 2.6 in. or 27.5 x 3.0 in. (27.5 in. wheels not included)
    • Flip Chip technology integrated into the shock link mount allows quick adjustments to bottom bracket height and head tube angle with just a hex key or multi-tool
    • In high mode, Flip Chip sets head angle 0.5% steeper and bottom bracket 4mm higher for quicker turns and more pedal clearance, ideal for technical terrain and 27.5 wheels
    • In low mode, Flip Chip sets head angle 0.5% slacker and bottom bracket 4mm lower for stability at speed and lower center of gravity, ideal for flow trails and 29er wheels
    • Super Boost-157 standard 157 x 12mm rear spacing paired with a standard-width bottom bracket results in 432mm chainstays and plenty of tire clearance
    • Down tube fits 2 full-size water bottles
    • Top tube accessory mounts; full-length internal housing cable routing; stealth dropper post routing compatibility
    • Pedals not included
    • Specs and images are subject to change
