Description

The BIG.TRAIL is back and better than ever! Hailed by the international mountain bike press as one of the best trail hardtails around, Merida have further tweaked it so it goes up, down and along even faster - which obviously means more fun. With updated, progressive geometry, the new BIG.TRAIL builds on an incredibly successful heritage, with a slack head angle and extended reach helping tame the gnarliest trails and a steeper seat angle that makes climbing up to do it again a breeze. They’ve also given it a slicker and tricker look and improved the frame protection too, so it'll stay looking good for longer. Join the BIG.TRAIL family and enjoy hassle-free trail fun in spades.

A passion for trail fun, all wrapped up in a no-nonsense package. The BIG.TRAIL 500 offers handling that at inspires confidence and pushes you to go that little bit further in your search for true trail connection. Merida’s top-quality aluminium frame is paired a Rock Shox Psylo Silver RC Air 140mm travel fork, reliable 10 speed Shimano drivetrain and Shimano hydraulic disc brakes with a beefed up 4 piston front brake and burly 203mm rotor. A long travel dropper post adds confidence and capability to any ride while tough 29er Maxxis tyres round off this trail-ready package.
