I’ve not used them personally but I know who they are. We use their ski shop (Edge & Wax) for everything we need for skiing/snowboarding and they are incredibly thorough, as in everybody I know will always use them above anybody else.
Had a couple of mates take their bikes over to them and with generally positive results. Couple of minor niggles that have arisen but the type that only become apparent when riding hard and not under shop testing if you know what i mean.
I wouldn’t hesitate to use them myself, hope that helps.
