Onza HO2 flat pedals


THE HO2 PEDALS have been designed to be as thin as possible at the edges in order to increase ground clearance and avoid the pedal strikes that are common with modern slack-and-low bike geometry. They run on sealed bearings and DU bushings, which should keep them spinning smoothly even in the grimmest weather, and they’re a good weight, especially considering the cost, with our pair weighing just 314g.

Measuring just 9mm deep at the outer edge, the HO2s are some of the thinnest pedals on the market, but this comes at a cost. Rather than using a concave platform (where the middle is lower than the outer edge) to cup your feet, Onza have gone with a convex profile (where the middle is higher than the outer). And that’s not the only unusual feature. The eight pins per side are also short and stout, rather than tall and thin, so they don’t dig into the soles of shoes particularly well.

These two factors add up to a pedal with very little grip, especially on wet and rough terrain, where we found our feet constantly slipping and sliding. Instead of the reassuring feeling of your foot ‘sitting into’ the pedal that you’d get with a concave platform, the lower outside edge and raised centre bulge over the axle makes the outer pins even less effective, leaving you feeling perched rather than planted on the HO2s.

A wide, thin profile is nice in theory, but the central bulge and short, stout pins mean the HO2s lack grip

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.

Trek Session Evolution

In this series we’re looking at the evolution of three bikes that enjoy enduring popularity with UK riders. Each fits into a different category – we’ve had a hardtail and a full-suspension trail bike, so for this final feature it’s the turn of the long-travel bike. And few ‘big bikes’ have undergone such a transformation as the Trek Session, which had a bit of a confused birth at a time of overlapping disciplines but has evolved into a sleek, lightweight race bike with multiple World Cup wins to its name.
