The Thomson X4 Stem drops weight by using a more traditional split clamp for the steerer interface, rather than an internal wedge. The sculpted stem relies on sleek clamp bolts, and, true to Thomson's design ethos, the X4 is CNC machined from 7000 series aluminum alloy.

The stem has a 31.8mm clamp diameter and comes in Black or Silver. The Thomson X4 Stem is available with a zero- (90) or 10-degree (100) rise, with lengths ranging from 50mm to 130mm.

Thomson, made in the good ol' US of A. Over the years I've had everything from a 50mm up to a 120mm on my rides. They are so good, I just can't seem to quit them.
