Experience the versatility and durability of this dedicated drop-bar trail bike, expertly crafted for confident handling on single track, double track, and a variety of rugged terrains.

Designed with mountain geometry tailored around a comfortable drop-bar hand position, it delivers a lively and responsive ride perfect for all-day dirt adventures and quick bikepacking excursions. Built around robust 27.5” wheels, this bike features front and rear thru-axles that provide exceptional stiffness and precise handling. Its frame accommodates internally geared hubs and single-speed setups, thanks to a proprietary horizontal-slotted dropout spacing that supports both 142mm and 148mm rear hubs. Constructed from 100% high-quality Chromoly steel, the frame and fork utilize proprietary double-butted tubing with a 1-1/8” headtube, ensuring a rigid, non-suspension corrected structure that balances strength and ride comfort. The frame is E.D. coated to enhance longevity and resist corrosion, making it a reliable companion for years to come. Additional thoughtful features include seatstay-mounted bottle bosses and multiple three-pack mounts located at the top and bottom of the down tube, enabling ample storage options for hydration and gear. Stealth dropper post routing is integrated for seamless upgrades. This bike offers generous tire clearance up to 27.5 x 2.8” with or without fenders, allowing for versatile tire choices to suit various trail conditions. Equipped with disc brakes for confident stopping power and a rigid steel fork that complements the frame’s durability, it stands out as a dependable touring bike ready to tackle diverse outdoor challenges.
