Race Face Atlas stem


AVAILABLE TO SUIT both size bars and with a super-short 35mm length option in the larger diameter, there’s an Atlas stem to suit most tastes. The faceplate uses 4mm bolts, while the steerer clamp has bigger 5mm bolts.

This means you need two Allen keys to fit the stem, but keeps strength up where it’s needed most, while saving weight elsewhere. Our 50mm example weighed a respectable 148g, yet felt as stiff as anything here, while the 40mm stack height and bombproof construction provide a rock-solid connection to the fork.

The greased steerer bolts are rated up to a torque setting of 13.6Nm, which is more than ample to hold the stem firm on the steerer – ours stayed in place despite some big crashes during testing. The interlocking faceplate is a neat design that cradles the bar securely. It’s also claimed to spread the load of the clamp evenly to prevent damage. Angle markings around the bar clamp help with set-up, especially when used in tandem with Race Face bars. It’s well finished to boot.

The Atlas may not be the cheapest or the lightest stem in this test, but it’s not far off on either front, falling into the top half of both categories. Crucially, it’s also well thought out, easy to use and as sturdy as you’ll ever need. It’s available in a choice of three colours – black, red or blue – too. Overall, we think the Atlas delivers the best balance of performance and cost.

LENGTH(S): 35, 50, 65mm

COMMENCAL EL CAMINO 3

Commencal are going from strength to strength at the moment and they’ve taken their tough trail hardtail bang up to date with 650b wheels. With its skinny rims, crankset and fork, the El Camino certainly isn’t perfect and it’s the least hardcore bike here. The handling, smoothness, speed and all-round agility of the basic bike still make it a real blast for technical trail riding though, and it’s a great base for upgrading over time.
