Sculpted in Titanium

The Roost Dominator Ti stem is an absolute masterpiece crafted out of a chunk of billet G5 titanium also known as 6AL-4V. G5 is well known for its high strength, low density, and corrosion resistance properties, but its expensive.

G5 titanium (often found in parts for F1 racing, gas turbines, aerospace etc) is also used in sections of our frames for extra strength and stiffness. Many Titanium MTB stems are mostly made from G9 titanium tubes welded together which results in a not-so-sexy looking tuby thing that handles like a wet noodle.

We wanted to design a stem that was not only the sexiest stem on the market but had performance, quality, and bling like all products from Roost Bike. It has a straight 35mm reach and is available in both 31.8mm and 35mm clamp sizes.

Features 31.8 and 35mm clamps.

  • Short 35mm length
  • 0º rise
  • Super stiff design
  • CNC billet 6AL-4V titanium
  • Stack height 40mm

Technical Info

When installing the stem tighten the two top bolts first, it is designed to have no gap at the top. Then the lower bolts should be tightened. All bolts at the bar should be torqued to 6-7Nm with the steerer bolts torqued to 8Nm.

The stem is raw finish, if you want brushed finish like the Roost handle bars give it a rub with a scotch bright pad but be carful of the logos. Most customers prefer it in the raw finish.
