All Mountain Style Om 45 stem


NAMED AFTER DR OM – a scientist who reckoned the human soul weighed exactly 21g – the Om 45 has been designed with a firm focus on reducing weight.

The low-stack design means it takes up little real estate on the steerer (just 34mm), but the result is noticeable flex when wrenching on the bar, particularly if there are a few spacers fitted underneath. The dual faceplate sections are easy to install and the super-wide 54mm clamp grips the bar well. AMS have used 4mm bolts throughout. The recommended setting of 5Nm allowed the stem to twist on the steerer quite easily, so we went a bit tighter. At 134g it’s light, and AMS claim the 31.8mm version weighs just 121g – 100g more than the human soul. Either way, the price is soul crushing.

WEIGHT: 134g (45x35mm)
LENGTH(S): 45mm
CLAMPS(S): 31.8, 35mm

Price 202$ (approx 162$)

Merida Big Nine 100

Wit the bikes swapped over, we head out on the same loop again, this time on the 29in Big Nine 100. Whereas the Big Seven was snappy off the line, the 29er takes a couple more pedal strokes to get up to speed. That said, once it's up there, it's easy to keep the big wheels rolling, allowing us to cover ground with ease. The fire road is at times a little rough, and the bigger wheels roll over the imperfections so we barely notice them.

Chromag HiFi 35 (50mm) stem

This is a seriously solid stem. Chromag use 5mm Allen bolts throughout, which makes it that bit easier to fit because you don’t have to swap tools. Once torqued up to the recommended 6-8Nm, it clamps both steerer and bar solidly, with no appreciable flex. We couldn’t get it to twist on the steerer, either in our static test or when riding. It’s also available in a 35mm length and three other colours. At 204g the HiFi is the heaviest stem on test by some margin, despite being one of the more expensive offerings here. Price $112

CANYON NERVE AL 8.0

  S ince their entry into the UK market a few years ago, Canyon have made a name for themselves as purveyors of well-made bikes that exhibit often extraordinary value. The secret (or catch, depending on your point of view) is that the brand don’t have dealers – they ship bikes directly to your door.

Cannondale Trail SL 29 SS

The fat aluminium tubes are a constrast to the skinny items seen elsewhere in the test, but this rigid Cannondale uses them to create one of the most old-school - and lightest - rides here.

Scott Scale 750

We continue to swap over our different wheel sized sparing partners and returning to the 750 from a lap on the Scale 950, immediately, the smaller wheel and thus smaller fork means there's extra stiffness up front. It's still not as stiff as we'd like, a bolt-thru axle here would still be appreciated, but hitting the first few berms is more accurate and thus a touch faster.
