An expensive option maybe, but a lightweight one that carbon bars in particular will be grateful for

Canada’s Joystick has an expanding range of MTB products, including this nicely thought through stem. CNC machined and available for both 31.8mm and 35mm bars, it employs a novel clamping system.


The faceplate has to be clipped on to the bar, then bolted on to the stem via the top two bolts. This allows for easy set-up and centring of the handlebar before the bottom two bolts are added.

Another advantage to this system over a regular four-bolt faceplate is that it removes the possibility of the bolts being tightened differently, leading to uneven stress on the bar – something that’s particularly important to avoid with carbon bars.


On the trail, our 50mm sample revealed no significant flex and didn’t suffer any creaking despite some hard riding with a stiff and wide bar attached. The 149g weight is very reasonable, but the price is a little heftier.
