Nukeproof Mega 275 Pro Bike


The Mega has gone through some serious changes for 2018 and now comes with a metric shock, widened Boost rear end and 170mm fork. Sizing has changed dramatically on the large and XL bikes too, though the small and medium stay roughly the same. We tested the medium and – while the reach isn’t the shortest on test, at 435mm, and our 5ft 8in main tester felt comfy enough – the general consensus was that it could do with being a touch roomier. The seat angle is quite steep, at 75.5 degrees. Combined with the 585mm effective top tube length, it sits you quite upright when climbing, so we wouldn’t want to run a shorter stem than the stock 50mm unit.

Get out on track and those sizing concerns feel less important, thanks to just how playful and fun the Mega feels. It’s eager to pop from obstacle to obstacle, or change direction with a split second’s notice. While the ride is a little livelier than that of some of the longer bikes here, the well-controlled, balanced suspension keeps your tyres stuck to the dirt and prevents too much clatter being transmitted through your hands and feet. That means you can ride fast, run after run, without fatigue slowing you down.

Get on the gas and the light Mavic wheels spin up to speed rapidly, while power delivery through the frame feels direct and responsive. The slack 63.9-degree head angle boosts confidence as the trail steepens, and the support and composure of the Lyrik fork up front means it’ll keep your front wheel tracking the terrain without diving through its travel. At the rear, there’s a decent amount of support for pumping undulations or carving turns and, with a single volume spacer added, enough progression to take the edge off harsh bottom-outs.

We’re massive fans of the SRAM Guide RE brakes, which deliver oodles of easy-to-control power. And high-fives to Nukeproof for using Maxxis tyres with reinforced ‘Double Down’ casings, which let you run lower pressures with less chance of puncturing. The wheels do feel quite flexy when pushing hard, though, and, at 25mm (internal), aren’t exactly wide. Some more robust hoops would make this great bike ride even better.

Sizing won’t suit all, but if it works for you, the Mega feels fun, capable and controlled

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
