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 is also used in sections of our frames for extra strength and stiffness.

Titanium MTB stems are mostly made from G9 titanium tubes welded together, they are UGLY and not so stiff.

At Roost bike 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.

You would normally find G5 titanium in parts for F1 racing, gas turbines, aerospace and it is extensively used in Boeing aircraft.

Features 31.8 and 35mm clamps.

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

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. Nm 6-7


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 leave it raw.
