The stem is good, but the bolts stripped out way too easily. I'll need to get new ones but I don't know if it stripped from my tools or the bolts. Great stem, but I didn't get any rides on it since it also wasn't holding the bars properly so they were moving.
Solid performing stem but the range of adjustment is only 45-50mm. If you are looking to get down to 40mm look elsewhere.
This direct mount is great the height is adjustable and holds a 35mm bar at just the right position. Simple solution to fine tuning your cockpit. Once again a great Hayes product to add to my build.
