The Marin Bobcat Trail 4 27.5" is a capable hardtail built for fun, confidence and progression on real off-road terrain.

Key Features:
- Series 2 6061 alloy frame with low standover and modern trail geometry
- SR Suntour XCM HLO-DS fork with 120mm travel and hydraulic lockout
- Shimano CUES 1x10 drivetrain with clutch mech for stable shifting

The Bobcat Trail 4 27.5" is built for riders who want a proper mountain bike feel without over-complication. Marin’s Series 2 6061 aluminium frame balances durability with comfort, offering a low standover to boost confidence and modern geometry that feels stable at speed but still agile in tighter sections. Internal cable routing keeps the bike looking clean, while dropper-post compatibility ensures easy upgrading as your riding develops.
Up front, the SR Suntour XCM HLO-DS fork brings 120mm of travel to smooth out rooty climbs, rocky descents or rough canal paths. The hydraulic lockout feature helps you stay efficient on firmer terrain or climbs by reducing fork movement when you don’t need it.
Shimano’s new CUES 1x10 drivetrain is a standout upgrade, offering crisp shifting and long-lasting reliability thanks to LINKGLIDE technology. The wide 11–48T cassette and single chainring make gear selection simple while still giving you plenty of range for steeper gradients.
Tektro M280 hydraulic disc brakes provide dependable stopping power in all weathers—ideal for UK trail conditions. Paired with WTB Trail Boss Comp tyres, you get predictable grip on loose surfaces with a tread pattern that balances rolling speed and traction.
Strong double-wall rims, a wide riser bar, short stem and a supportive Marin MTB saddle round out a build designed for comfort and control.
Whether you’re new to the trails or looking for a capable hardtail that won’t hold you back, the Bobcat Trail 4 27.5" is ready to help you progress with confidence.
