Key upgrades over the Bobcat Trail 3:
- Shimano Altus 2x9 drivetrain
- SR/Suntour XCM HLO DS fork
SERIES 2 ALUMINUM FRAME
The Bobcat Trail has a Series 2 aluminum frame that features double butted 6061 tubing, internal cable routing, and forged 135mm open dropouts that ensure a stiff and light frame package. Available with 27.5” (S/M frames) or 29” (M/L/XL frames) wheels, depending on size and preference.
29” OR 27.5” WHEELS
The Bobcat Trail has a growing wheel size strategy for the best fit and performance with the choice of 27.5” or 29” platforms on the size M, 27.5” wheels on sizes XS and S, and 29” wheels on sizes L, and XL.
TRAIL GEOMETRY
All Bobcat Trail models feature Marin Trail geometry, featuring a long-ish reach, low standover, slack head tube, and steep seat tube angles, giving riders confidence and predictable handling to have a blast on the trail.
FASTBACK SEATSTAY DESIGN
Fastback seatstays add vertical compliance without sacrificing power transfer, and feature rack mounts for extended trail adventures.
INTERNAL DROPPER COMPATIBLE
Bobcat Trail models have a 30.9mm seatpost and internal cable routing ports for future dropper post compatibility.
