Sendero Steel Mountain Bike

Input from our factory team and our passion for technical singletrack have led us to design a refined downcountry capable trail hardtail. The Sendero is built to excel in the varied untamed trails most of us have access to. Inspired to unlock the rock gardens and ledge lines found across Austin’s mountain biking trails. If you go out of your way to ride the hard line, we made this bike for you. The Sendero stands out from other bikes in the category with a higher bottom bracket and steeper seat tube than many other options. The reach is optimized for precise steering with stem lengths between 35mm and 70mm. Travel options are 120mm or 130mm travel. The super short 420mm rear end can clear up to a 29x2.8” tire due to sliding PMW Stainless dropouts. The Sendero represents a balanced and versatile offering in the burgeoning downcountry category.

Ride Quality

  • The Sendero utilizes a short 420mm chain-stay & a long reach to position the rider to stick corners and pedal efficiently while keeping the bike incredibly playful.

  • Paired to the head tube and seat tube angles the design is made to confidently huck ledges and bomb descents.

  • A balanced Bottom Bracket: Positioned to bring out the rest of the geometry and give clearance to pedal through technical rock gardens, climb with power and stay flickable.

  • Smooth and predictable compliance from CHUMBA Oversized Select Double Butted Tubing, built of the best tubing available.

  • The Sendero steel is designed to unlock technical trail features, put a smile on your face and of course to SEND IT!

Build Quality

  • Made in house/USA quality

  • CHUMBA Oversized Select Double Butted Tubing and PMW stainless steel sliding dropouts, mean this bike will exceed your expectations and provide years of reliable trail service. Oversized tubing yields larger tube miters for strength.

  • Seat-stays and chain-stays are a size up from our XC/trail Stella design.

  • A custom bent seat tube brings together a short rear end, steep seat tube angle and maximum tire clearance.

  • Clean thoughtful cable routing

  • Flawless frame miters, all tubes are heat sunk and argon purged when welded to prevent distortion and material thinning.
