No idea I'm afraid - came as just as much a shock to me too. I understand the shop was shuttered as of yesterday morning.
I'm gutted - they've always been my go-to LBS for anything I can't sort myself. Had been meaning to pop along and pick up a couple more of their branded water bottles too..
I'm shocked to hear about M Steels, do you know if it was a financial or health issue that has forced this closure, ? Fingers crossed everyone is well
