Transition Smuggler Carbon GX Complete Mountain Bike 2025

The Transition Smuggler Carbon GX Complete Mountain Bike is a trail bike chameleon that turns “should we ride this?” into “how fast can we take it?” Progressive suspension and snappy, confidence-inspiring geometry keep things composed whether you’re pedaling or descending, while dual 29-inch wheels provide the stability and speed you need to keep crushing all day long.

Carbon Fiber Frame
–
Lightweight and incredibly strong, Transition's carbon framesets are known for durability and versatility.

Travel
–
140mm Front / 130mm Rear

Wheel Size
–
29"

Speed Balanced Geometry
–
SBG ensures the bike maintains low speed agility, front wheel traction, and proper rider weight balance while actually increasing confidence in steep terrain and at high speeds. With SBG, a slacker head tube angle is combined with an all new reduced offset fork standard, preventing the front wheel from being too far in front of the rider. This improves front to rear weight distribution on the bike, which is often out of balance on long and slack bikes. One of SBG's greatest benefits is that it creates a confident steering feel that adapts to wheel speed. More stability when going fast, more agility on technical slow speed maneuvering as well as improved traction, control and confidence for any skill level of rider.

GiddyUp Suspension
–
A wide usable sag range of 25 – 35% allows the rider to tune the feel of the bike; from firm and snappy, to more supple and active. Wherever you end up, you can focus on the trail without remotes, levers or knobs. Just grab your bike and GiddyUp.

Progressive Kinematics
–
With a little over 27% progression through its travel, this bike gives an almost bottomless feel in a mid-travel package. Its 130mm of rear travel can easily be upped to 140mm, and it's even compatible with a coil shock.

Rattle-Free Headtube Cable Routing

Universal Derailleur Hanger
–
SRAM's Universal Derailleur Hanger is available at almost every bike shop, should something go wrong.

  Frame Material

  Carbon

  Carbon is a composite frame material. Unlike metals, carbon is composed of fibrous strands woven into a grid and bonded with epoxy. Carbon is favored by many for its lightness and stiffness but its complexity in fabrication makes it the most expensive option.
