The Marin San Quentin 3 29er Hardtail Mountain Bike is for the aggressive hardtail trail rider looking for a blend between singletrack capabilities and extended air time. Developed in conjunction with freeride legend Matt Jones and taking its name from the most rough and tumble piece of Marin County, the San Quentin collection lives up to the notoriety of the namesake maximum security California State Prison. Blending the strength an style of an Alcatraz dirt jump frame with the natural trail savvy of the best hardtails, the San Quentin family of aggressive trail hardtails is the perfect mash-up for the modern trail rider.
The San Quentin 2 and 3 feature Series 3 aluminium frames, 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, and a sexy paint job. 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. San Quentin 2 and 3 models feature ISCG 05 tabs for easy chain retention device installation for rowdier riders.
The Marin San Quentin 3 29 is the top of the range model but still comes in at an affordable price. It comes with 29" wheels, a TranzX dropper post, Marzocchi Bomber Z2 suspension fork, TRP brakes, Maxxis tyres and plenty of awesome Marin kit to create a bike you’ll love to rip, but that won’t shred your budget.
Mountain bikers who want an aggressive hardtail that can handle trail rides and bike parks so you can hit big jumps and hammer singletrack on the same ride.
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.
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.
