This Trek Marlin 7 Gen 3 Grey is available with our legendary Podium Point free accessory scheme.
Total trail confidence. The Trek Marlin is a real standout performer in its category with a fantastic frameset and a great specification.
The all new Trek Marlin features an Alpha Silver Aluminium frame with modern trail-bike updates: a slacker headtube, longer reach and wider bars, all which boost confidence for taking on harder trails. Plus, there's clearance for grippy 2.4" tires on all sizes.
If you get a little too rowdy trying out the rock garden and need to fix a flat? The all-new Thru Skew rear axle makes taking the rear wheel off and putting it back on a breeze for riders, thanks to a closed drop-out system that is safer, simpler and stronger. You can even pocket the removable lever for added security or a cleaner look.
Updated cable routing means Marlin is now compatible with internally routed dropper posts! The Marlin also comes with foam tubes wrapped around the internally routed derailleur housing and brake hoses, silencing rattles from inside the frame, while a new full-coverage chain stay guard quiets chain slap and gives the Marlin a trail-ready look.
Marlins are size proportionally all the way through the range. The smallest XXS size features a curved top tube and 26" wheels. XS and S sizes features 27.5" wheels whereas the larger sizes feature 29" wheels. This means all sizes are appropriately sized and balanced for the typical rider.
IMPORTANT: This bicycle is supplied without pedals. Pedals for this bicycle can be selected for no cost using Podium Points™.

Sizing information is provided as a general guide only. This is based on the average rider riding the bicycle in the style for which it is intended. This takes no account of a rider's personal proportions, physique, flexibility and biomechanics. If your height places you on, or near, a bicycle size step then we recommend you consider both sizes. All bicycles offer a range of handlebar and saddle adjustment which will enable you to fine tune your riding position once the correct size has been established. If you are unsure on sizing, we strongly recommend you visit our store so we can assist you. Pedal On offers advice and information on sizing in good faith, the final decision and responsibility on which size to purchase is yours.
