I couldn't agree more with the @greencat reply. £60 for the time, expertise, equipment and materials to make good a broken frame is peanuts, and especially to do this in a timely way.Think what some are missing with VB is choice/trade off. VB are quick and relatively cheap. I had a bike repair turned around in a week for around £60 - and neither repair failed. I'll take less than pretty if the price & speed is good.
Some of the other frame repairing names either didn't get back to me at all/after wanting a pic of the crack or suggested it would take months.
I admire Dave from @Vernon Barker Cycles for coming on here to defend his work.
I have seen examples of spendy steel custom frames on retrobike that have cracked - arguably because too much material has been removed and the integrity of the frame has been compromised. In this situation someone is left with an unrideable £4K frame. I see what VB offers as a refreshing polar opposite to heavily marketed expensive stuff that breaks.
