Marin San Quentin 1 (Black Grey)
740683002
A budget-friendly hardcore hardtail for the rider who wants a bike built for climbing hard and descending fast on rough trails, with modern trail geometry that doesn't get softened just because the price does.
Overview
The San Quentin 1 is Marin's 'bang-for-your-buck hardcore hardtail' - a Series 2 6061 aluminium frame built with the same modern trail geometry principles as Marin's full-suspension bikes, just without the rear shock. The idea is simple: a rigid rear end that's light, direct and efficient, paired with a proper 130mm-travel coil fork up front to take the worst of the trail hits off the front wheel.
It's equipped with a 1x9-speed microSHIFT drivetrain (32T chainring, 11-46T cassette) with a clutch-equipped derailleur to keep the chain under control over rough ground, Tektro M275 hydraulic disc brakes on 180mm rotors front and rear for strong, consistent stopping, and wide 2.5in tyres on tubeless-compatible rims for grip on loose and rocky surfaces. The bike is offered in both 27.5in and 29in wheel options, so the ride character can be tuned toward either agility or roll-over.
This is the bike for a rider who wants to climb and descend hard on genuine trail terrain without paying for rear suspension they may not strictly need - someone who values a direct, efficient pedalling feel on the way up as much as confidence on the way down.
Why You'll Like It
A coil fork that actually works
130mm of coil-sprung travel from the SR Suntour XCM34 soaks up square-edge hits that a budget air fork often struggles with, giving real descending confidence.
Gearing built for steep trail climbs
The 11-46T cassette on a 32T chainring gives a genuinely usable climbing gear, which matters on technical, punchy trail climbs rather than smooth fire roads.
Big rotors for hard trail braking
180mm rotors front and rear with Tektro hydraulic brakes give the stopping power you want when speeds pick up on a descent, not just token braking.
Wide tyres with real volume
At 2.5in wide and tubeless-ready, the stock tyres offer meaningfully more grip and cushioning than a narrower hardtail tyre, especially once run tubeless at lower pressure.
Two wheel sizes, one geometry philosophy
Choosing between 27.5in and 29in lets a rider pick agility or roll-over speed without compromising on the bike's modern trail geometry either way.
Who Is It For?
The San Quentin 1 suits a rider who wants a genuinely capable trail hardtail for climbing and descending on real singletrack, without the extra cost and maintenance of a rear shock. It rewards an active riding style - someone who's happy to let their legs and arms do some of the work a rear shock would otherwise handle.
In India, this fits a rider based near one of the country's MTB trail networks or hill-station riding spots who wants a hardcore hardtail that won't buckle under aggressive trail use, and who'd rather put the budget saved on a shock into tyres, a dropper, or trail time.
It's also a strong next step for a rider moving up from an entry-level hardtail who wants more descending confidence and bigger brakes, without jumping straight to a full-suspension bike.
Good to Know
The tubeless-compatible rims and tyres mean a tubeless conversion is straightforward whenever you want lower rolling resistance and better pinch-flat protection on the trail. The clutch-equipped rear derailleur keeps the chain quiet and seated over rough ground, so drivetrain noise and dropped chains stay rare even on rough descents.
