Barron Cycles at Stow (just North of Lincoln).
Proper Family business.
I do almost all of my own maintenance on a variety of machinery, so I hardly ever go in with an easy request and even more rarely come out without the answer.
99+/100 I come away with the parts in my pocket, plenty of free advice, and all at a sensible price. 😀
The best one ever was a mech hanger to replace a broken one on my old rigid MTB, I’ve never seen the brand of bike before or since – Quasar – but Mr Barron produced an identical hanger from a box of “various” items.
