The BIG.TRAIL 300 is a fun-packed and hugely capable trail bike at an amazing price. Its progressive geometry combined with a long travel 140 mm fork and grippy 2.4" wide 29er trail tyres make it the perfect companion for exciting trail sessions and challenging all-day rides over rough terrain. And the long list of exciting features and upgrades adds to its premium looks.
The BIG.TRAIL is back and better than ever! Hailed by the international mountain bike press as one of the best trail hardtails around, we've 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. We'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. Available from XSmall to XLarge, perfect for finding your preferred size and reach options.
