The TR450 is our dedicated downhill racing machine. Heavily researched and selected with direct input from the Transition Racing Team, this is an aggressive geo built for speed and stability. With a careful ratio between chainstay length and head angle, the frame has a neutral feel in corners with good rider weight balance between the front and rear wheels. The TR450 gets 8.25” of travel from a 9.5” x 3” shock placed low in the front triangle.
The linkage was tuned to provide a gradual change from beginning to ending leverage rate. The suspension ramps up very evenly through the travel to give the bike a supple top stroke and good bottom out control without excessive sag or mid stroke wallow. This result is a consistent progressive suspension feel that is predictable and yields a high amount of tunability. We set out to make the cleanest looking DH bike on the market that could be ridden hard and put away wet while being a dependable top level race bike you can trust.
