New model for 2026 - please get in touch for availability

The Marlin 7 is your best friend on the trail and wherever else you roll thanks to its confidence-boosting trail geometry. It finds the perfect balance between price and performance with a RockShox suspension fork that makes quick work of rocks and bumps in your path, and loads of gears from the SRAM NX Eagle 12-speed drivetrain.

You want a go-anywhere trail bike that's got upgrades where it matters most, but won't break the bank. You want to build skills on the trail, and need a bike with confidence-inspiring geometry.

A lightweight aluminium frame with modern trail riding geometry and internal routing that keeps cables protected and keeps the bike looking sleek. A 100 mm RockShox Judy suspension fork that smooths out rowdy trails, upgraded 12-speed SRAM NX Eagle shifting and the serious stopping power of hydraulic disc brakes.

The Marlin 7 is the go-to trail bike for those wanting to build skills on the singletrack and get the best bang for their bucks with upgraded suspension and confidence-inspiring geometry.

- You get real-deal modern mountain bike geometry that keeps handling confident when you're on singletrack, but is versatile enough for use on roads and bike trails too

- You get a RockShox fork with 100 mm of suspension that turns rocks and roots in the trail into smooth-sailing and upgraded 12-speed SRAM Eagle shifting

- Mudguard mounts make it easy to accessorise, so your mountain bike can double as a rugged commuter

- Internal routing makes it easy to add a dropper post that lets you lower your saddle on the fly for more confident descending

- Marlin models in sizes XXS and XS have a curved top tube and lower standover height that makes it easier for smaller riders to mount and dismount

Will my bike have a curved top tube?

Smaller frames have a top tube that dips down as it approaches the seat tube. This design makes for a lower standover height, which is good for shorter riders because it allows them to straddle their bike more easily. Larger frame sizes have a straight top tube because taller riders with longer legs typically don't have the same issues with standover height.

Fit for every rider

Marlin comes in seven frame sizes to suit riders of any height, and Smart Wheel Size ensures you're on the fastest wheel that fits. The smallest sizes even come with short-reach brake levers and narrower handlebars that give smaller riders better comfort and control.

High tech, high value

Marlin looks and feels great. It's packed with features usually found only on more expensive bikes, like a stylish frame with internal shift cable and brake hose routing, which can help your cables last longer by protecting them from the elements.

Upgrade your pedals and love your bike more

Pedals are two of the five touchpoints that connect you with your bike, and even though this bike comes with a pair, upgrading to pedals that boost control and grip will greatly improve your ride. See the pedal guide and find the best pedals for your riding style. We recommend flat pedals for simple versatility.
