Merida BIG.NINE 5000 2021 review

Jul 2020

The 2021-model Merida BIG.NINE 5000 is a well rounded XC bike that makes light work of longer rides, but is still capable enough to make the downhills fun. Its well-rounded spec and decent fork mean its good right out of the box, but that lightweight carbon frame means it's entirely worthy of longterm upgrades.
