The last time we lined up Merida’s Big Trail in a bike test against the best hardtails on the market it was quite a different machine. All models rolled on 27.5×2.8in Plus size tyres and at a time when trail bike sizing and geometry was evolving rapidly, its dimensions and angles felt a touch dated. But Merida didn’t take it lying down, and given that the UK has always been a hotbed for trail bikes – especially those with a harder-hitting nature – Merida consulted its dealer base for feedback, leading to a fully overhauled Big Trail platform with a completely different outlook. Frame A sleek aluminium frame is still at the heart of the Big Trail 600 but it’s now designed around 29in wheels and a 140mm travel fork, and is available in five frame sizes. There are four models starting at £1,175, we picked the Big Trail 600 at £1,675, one down from the flagship bike. There’s plenty to talk about with the new frame. At first sight we thought we’d been shipped the wrong size – not the XL we’d requested – but we needn’t have worried. Part of Merida’s new design is to build the frames around shorter seat tubes (taking advantage of modern 170-200mm droppers that are now available) and it was the short 455mm seat tube length that misled us. It gives buyers the option to consider reach and top tube measurements as a priority and move up a frame size without compromising on standover height. Its vital stats also stack up well, and while not ground-breaking they are a major leap forward from the previous generation. The 65.1º head angle, 308mm bottom bracket height and 1,225mm wheelbase are all on the money. Merida has packed the Big Trail frame with neat details as well as an exceptionally smooth finish. The down tube sports two bottle cage mounts and there’s an on-trend accessory mount under the top tube, along with SRAM’s universal gear hanger. Suspension There’s a Marzocchi Bomber Z2 up front, but gets 10mm more travel than the one on the Nukeproof Scout 290 Comp. In fact, it’s the only bike in the test with a 140mm fork. Like most forks on other modern hardtails, with the exception of the steeper Kona Honzo, Merida uses a shorter 44mm offset crown to work with the modern geometry and help keep the steering sharp at lower speeds. So what once was a custom tweak has now become the new norm. With a longer travel fork and the option to upsize, Merida has kept the head tubes at a more generous length. And with no conical top cap on the headset there’s still the option to slam the stem to load the front wheel – and we certainly took advantage of that. Components It’s a heavy dose of Shimano for the Big Trail 600 and that extends to the hubs, rotors and neatly integrated dropper lever. The only major deviation are the cranks, which are from …Continue reading »
