Marin named their new XC bike, the TAM, after Marin County's Mt. Tam, which is arguably one of mountain biking's birthplaces

Apr 2026 · Dario DiGiulio
The Tam features 120mm of travel and aggressive geometry for an XC bike.
Aggressive geometry with 65° head angle
Stable and easy to intuit geometry
Good balance of XC efficiency and trail ride quality
Competitive weight potential (27.8 lb with lighter build)
Room for two water bottles
30.9mm dropper post compatibility with up to 370mm insertion
Max tire clearance 29x2.4"
200mm rear rotor clearance
Suspension design with good pedaling platform and active braking
Internal cable routing unguided, noisy without foam
Minimal chainslap protection; Di2 drivetrain slaps
Handlebar sweep feels odd to the reviewer
Twisty and flat cornering less sharp than traditional XC geo
