Trek just launched the latest iteration of its best-selling mountain bike, Marlin. In its fresh form, Marlin boasts an entirely new frame that elevates stability for riders honing their skills with all-new geometry and fresh features that inspire confidence and capability wherever it rolls. 

Marlin features a new Alpha Silver Aluminum frame that gets modern trail bike updates, like a slacker head tube, longer reach, and wider bars to elevate confidence when tackling more difficult terrain. The frame is paired with a 100mm fork to soak up roots and rocks, and can even be upgraded to a 120mm fork on sizes XS and up as riders progress and want more from their ride. The new frame also increases tire clearance, so riders will be able to roll with beefier 2.4˝ tires that boost grip and soak up rough trails.

Securing the rear wheel is a new Thru Skew rear axle that ups wheel security. It secures into a closed dropout system for a safer, simpler, and stronger ride while retaining the existing 135mm rear hub standard. Plus, riders can stash the Thru-Skew’s removable lever for added wheel security and a cleaner look while riding.

All new Marlins feature updated internal cable routing for a cleaner overall look and added internally-routed dropper post compatibility. Internal foam tubes simplify cable routing and prevent cables from rattling on rough rides. To increase protection on the outside of the frame, Trek equips new Marlin with a full-coverage chainstay guard that quiets chain slap, shields from scratches and knocks, and gives the bike a trail-savvy look.

Trek continues expanding Marlin with an additional XXS size this year, offering a fit for shorter riders and growing kids. All bikes, size XXS through XXL, feature Trek’s Smart Wheel Sizing and thoughtful details to increase riding comfort. Smaller sized frames will feature a curved top tube to improve stand over height, and roll with wheels as small as 26˝, with wheel size increasing proportionally along with frame size.

For price-conscious riders, Marlin will still be available in its previous generation on Marlin 4 and 5, while Marlin 6, 7, and 8 will feature the all-new frame and latest technology.
