Gamut TTr direct-mount chainring


GAMUT’S DIRECT-MOUNT TTr ring is available in 28 to 34t sizes and fits SRAM GXP cranks with a removable spider. It’s also available in bolted versions for other cranks, including Shimano XT and XTR.

Fitted sans chain guide and used with a clutch rear mech, ours has survived its fair share of rough-and-ready riding without shedding its chain once (a problem we’ve occasionally suffered with other aftermarket rings). It’s holding up nicely after a few months of harsh weather and slop, and the 71g weight is competitive.

The price is level with Race Face’s GXP-compatible rings, but there are cheaper options available from other brands.

Price 82$

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.

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.

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.

SKS Airbuster CO2 inflator

The alloy Airbuster has a large knob so you can regulate the flow of gas, a mechanical stop to prevent the cartridge being pierced in transit and a dust cap to keep the valve free of debris. While it works with Presta and Schrader valves, switching between them requires a fiddly change of the valve head. The thin rubber sleeve doesn’t provide much protection from cold spent canisters. You can’t insert much of the valve into the inflator head, so you have to be careful to avoid leaks. Price $33 w/16g cartridge
