Thomson X4 Stem $99.95
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.

Solid, expensive for weight
- Familiarity: I've used it several times
Thomson x4 stem is very solid, great materials, great construction, looks good, and has +/-10 which fit my needs perfectly. my only gripe would be that the stem is a little on the heavy side given the price point. there are many alternatives to the Thomson x4 stem that cost 1/2 the price and accomplish the same task, so you are definitely paying extra for the Thomson brand. most of the time I would be bothered by that, but not as much here, given that this stem definitely delivers on its quality focus and offers the steeper angle (-10) that many others don't.
X4 on the Cross.
Dressed up with the blue face kit. I just had to have it.

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.
