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$)

ENVE M50 29" Wheels

Utah based company ENVE have been making drool-worthy carbon components for some years now. Despite the fact that carbon rims are becoming more and more common on mountain bikes these days, you can guarantee that ENVE wheels will be a talking point when someone is eyeing off a steed. Instantly, the big bold logos on each rim scream "fast", "light" and to some extent, "expensive" The kids call this 'bling'.

Scott Stego MIPS helmet

Scott’s top-end aggressive trail helmet is only available with MIPS, as the Swiss brand were early adopters of the system. The EPS extends low at the rear without clashing with the retention system and the strap attachment points are external to the liner, maximising the amount of material around the temples. This is the closest-fitting helmet on test, with very little clearance inside the liner. Despite this, and although the Stego has fewer vents than some other lids here, we never felt too hot-headed. Scott spent time developing the ventilation system using a wind tunnel and it seems to have paid off. The thin pads don’t offer quite as much comfort as some competitors’, and while the short peak is removable, it doesn’t offer any height adjustment. Weight 340g Sizing S, M, L Price $180
