The 2025 Marin San Quentin 2 27.5 Hardtail Mountain Bike is for the aggressive hardtail trail rider looking for a blend between singletrack capabilities and extended air time.
The San Quentin 2 features a Series 3 aluminium frame with more advanced tube forming, more complex dropouts, post mount disc tabs, full internal cable routing, and a boost 148mm thru-axle. Taking cues from the Alcatraz, the San Quentin line up provides all the benefits of the DJ style with massive stand over, slick frame tubes. The slack head tube angle paired with a steep seat tube angle create a ride that will fly uphill with perfect front wheel precision but then descend like it’s on rails. The balanced rider position thanks to the steep seat tube puts your weight between the wheels for impressive climbing and handling on flats, while the slack front end and short rear centre help to pull you through the rough descents and corners with an intuitive feel.
The San Quentin 2 is the mid-pack model that blends bang-for-your-buck value with kick-ass components. It comes with a TranzX dropper post, X-Fusion suspension fork, Shimano brakes and drivetrain, Vee Tire rubber and plenty of awesome Marin kit to create.
This bike is perfect for
Mountain bikers on a budget that can handle the toughest trails you can find. From steep downhills to jumps and berms the San Quentin can handle it.
Key Features
- Series 3 6061 Aluminium frame for 27.5 wheels
- X-Fusion Sweep Boost RC 140mm travel Fork
- 1x11 Speed Shimano Deore gearing and Tektro hydraulic brakes
Mountain Bike Buying Guide
Mountain biking is an incredibly diverse sport. Mountain bikes now come in three main flavours. They are XC, Trail and Enduro.
XC – short for cross country, are quick race bikes. They will normally have 29” wheels and come with 100mm of suspension. If you are mainly going to be riding bridleways and natural trails in the South East of England, where our shops are, an XC bike will be the quickest and most efficient option.
Trail – these bikes are designed to be pedalled up and down hill and for use on bridleways and natural trails, but also at dedicated trail centres. They normally come with 130mm or 140mm of suspension travel and can have either 27.5” or 29” wheels, but 29” is quickly becoming the norm. Trail bikes are good all-rounders. They won’t be as fast as an XC bike on the flat but they can handle a lot more challenging terrain, and a few jumps. If you plan on taking your bike to trail centres in Wales, or to the Alps, then a trail bike may be your best option.
Enduro – enduro racing is a thing in and of itself but many people buy enduro bikes for ‘aggressive’ trail riding and uplift days at places like Bike Park Wales. This generally means challenging downhill trails with some big jumps. With around 160mm of suspension travel enduro bikes can take some big hits. They are designed to be efficient enough to pedal up hills but really come into their own when pointed downhill. You get enduro bikes in either 27.5” or 29” wheel sizes as well as mullet setups of 29 at the front and 27.5 at the back.
Men’s and women’s mountain bikes
Nearly all the mountain bikes we sell are now unisex. All of the big brands have gradually stopped doing dedicated men’s and women’s bikes over the last few years. Instead they are focussed on producing bikes in a bigger range of sizes. So, for instance, the Trek Marlin 5 is a unisex bike that now comes in sizes from XXS to XXL large. This means it will fit riders from 4’ 5” to 6’ 5” and everything in between.
