If you’re after a properly stout stem this could be the solution. The 45mm longAmXTrail combines the increasingly popular 35mm bar clamp diameter with a decent width (63mm) to hold the handlebar like a vice.
The traditional four-bolt faceplate design means you need to take care during fitting to ensure the bar is central in the stem and the bolts are evenly tightened. TheAmXTrail felt flex-free on the trail and didn’t twist on the fork steerer, even after the occasional off.At 174g on our scales it’s no lightweight though. It’s available in grey or red as well as the black seen here.
