Evans Waterloo Road still have a decent selection of MTBs downstairs including hardtails and full-sussers (specialized, lapierre, bmc, kona, etc.) lots of tires, body armour, full face helmets, etc.
most stuff is available next day from that gigantic warehouse they have in Gatwick, rather than having lots of stores stuffed full of the same stock?
..bike sales in London are healthy and this involves mainly road/hybrid but MTBs figure in those sales too, I’ve heard from different sources that a store like Waterloo Road will normally reach £2 million in sales every season, and that is not the best performing store in the london portfolio
