Transition TR11 Alloy Downhill Mountain Bike Sram GX 2026

A race bike for the people

The TR11 was built from the ground up with a single purpose in mind, to go fast. Its DNA was formed between the tape, from World Cups to local races, and this new layout is a major step forward in delivering what riders today need for the toughest DH tracks, bike parks, and local shuttle trails. We built in all the features and tech any rider could need to go from grassroots to World Cup in an affordable and durable package. In the famous words of Nigel Tufnel, “These go to 11!”

The TR11 is all about speed, hot, nasty speed.

Forget what you think you know. The 11 is here to go fast. We dug deep into the needs of riders from local race series to the big show and created a bike ready to take you to the top step. From the geo to the leverage curves, we set out to give riders the best platform possible to succeed.

This one goes to 211 mm

Charge harder and go faster. The TR11 now features 211mm of rear travel so you can confidently push your limits with more traction and control. With two leverage curve options, the TR11 pairs nicely with coil and air shocks, allowing every rider to perfectly tune their setup to their style, track, and component preferences.

Downhill Specific Leverage Curves

The TR11 features a completely redesigned leverage curve with the option for a more linear or more progressive setup. The new curve has consistent progression that delivers an intuitive ride feel as the bike moves through its travel. It is easy to set up, easy to tune, and plays well with both air and coil shocks, giving riders flexibility without compromise.

Whether you are chasing traction in rough sections, relying on mid stroke support through compressions, or needing confidence inspiring bottom out resistance on big hits, the TR11 delivers a balanced and predictable suspension feel. With two distinct leverage curve options to choose from, riders can fine tune their setup for traction and support without having to sacrifice one for the other.

Features

The TR11 hosts a range of new features that make it robust, reliable, and allow riders to fine tune the bike to their preferences.

C.H.I.P.S.

Changes Height Independently from Progression SettingFine tune your geo with these simple and robust C.H.I.P.S. to adjust your head tube angle by 0.4 degrees and BB height by 6mm.

S.A.L.S.A.

Four chainstay length dropout options: 0mm, +5mm, +10mm and +15mm. Sizes Small and Medium come with 0mm while Large and X-Large come with +5mm dropouts. Additional dropout sets sold separately.

Gravity Cast BB Area

Creates higher strength and perfect alignment of the BB, main pivot, and shock mount area.

Bolt On Protection

Shred more and worry less with the new downtube protection designed specifically for our gravity focused models. Robust rubber downtube protection prevents rock chips and shuttle wear around the mid and lower downtube areas. These are held securely in place with two small fasteners and are easily replaceable when the time comes.

Reach Adjust Headset

Adjust your reach by plus or minus 5mm with the supplied headset cups.

Forged Rocker and Chainstay Yoke

To ensure the TR11 will take lap after lap, we built new forged rockers and chainstays, each with its own bridge to provide the perfect balance of weight and stiffness.
