UK Exclusive. One of the best things about Merida is that despite being one of the biggest bike manufacturers on the planet they're agile and listen to our local market feedback. The introduction of the brand new Shimano Deore 12 speed groupset was too good an opportunity to miss, so we took the template of the Big Nine 60 and upgraded it to 12 speed.
