The stems are stiff, well built and the finish and style is second to none. The alloy clamp plates are excellent and be safely torqued to recommended tension (5 Nm)

I had one with a red carbon fibre clamp which failed after 800/900km of light riding - i use a torque wrench to tension the bolts...... the alloy (grey) clamp plates are excellent.

Excellent Stems, Carbon clamps failed before 1000km. Alloy clamp is superior.

This is a review for the Oval R900 carbon stem of which I have used 3 in different lengths 70mm 90mm and 100mm all of them 31.8mm clamp size
