The Titanium Unicorn

The Roost Dominator Ti is the ultimate bike porn, trail smasher, roost machine and big travel Enduro rig. Undoubtably the rowdiest bike in our line-up, the Dominator Ti is a total trail slayer and a true work of art.

We are now at the Version 3 Dominator. After much testing and quite a few build changes, and still with a 63.8 degree head angle (sagged) and 76 degree seat tube angle, the Dominator puts you in the perfect position for a bit of pedaling and then dropping into long rugged fast descents.

The Dominator is designed as an Enduro bike that is well balanced and will take up all the knocks but is still effective on the pedal sections.  Taking some DNA from DH bike geo we made it a little slacker and the wheelbase a tad longer than normal. This keeps the wheels grounded when needed and stable at high speed over the janky stuff.

Ti Strength and Compliance

We wanted something you can smash on the toughest trails so we have really beefed it up;

  • The rear swing arm is 25mm diameter G9 titanium and almost double the thickness and diameter as other Titanium bikes.
  • The CNC gussets are G5 titanium, the work house of all titaniums.
  • The lower tube is 51mm diameter compared to 44mm on other frames. 

No need to wrap this baby: Never worry about shuttle scratches and damaged to your frame again with the brushed finish of the Titanium Dominator. A quick rub with a scotch bright pad removes scratches and brings the frame up like new again.

Floating Pivot Design

The Dominator is designed a unique floating pivot point for the rear suspension. This results in a much more effective system for eating those big bumps and hits and keeping your momentum preserved. The rear wheel is more active through rock gardens and rooty sections resulting in less hangups. In a nutshell: it means more speed through the rough stuff. 

The frame is made for an air shock keeping it simple to tune. A coil can be used with a progressive spring. The compatible shock is 230/60.

Build Features

All the cables are protected by neat and tidy internal cable routing within the frame and swingarm. Internal routing with some clever options make this a pleasure to build up with your preferred components.

The Dominator Ti is available in 29″ boost wheel size but a 27.5″ or Mullet setup can be fitted with a slight change in Geo.

All frames come with a headset and take a 73mm BSA bottom bracket.
