Afternoon and welcome @WandaFish
Does your father in law have an Ian May bike ?
I would love to see some pictures of it please .
There is little info about Mr May but the basic's are he ran a shop in the Merseyside area , he also sponsored a cycling team and competed in time trials as far as i can make out. He died quite suddenly and quite young and from what i can make out all the records of his business have never been found.
Over the years i have owned four Ian May decalled bikes but only 1 of them had an IMC prefixed frame number which as far as i have been able to find out were made by himself and they seem to be less than 199 of them . A lot of the bikes carrying his name seem to be nothing special one's that at some point for and for unknown reason's have his decals on ?
The other 3 that i have owned have all looked to have been quality hand made frames but none of them had no identification marks to enable me and many others to say who made them , 2 of mine have been aero style tubing and had Italian threaded bottom brackets it is thought that Simoncini and Daccordi both made frames of similar squashed profile tubing which ties in with the Italian threads .
Quite a few people have come forward with snippets including at one point his sister but to this date i have not uncovered a lot of info .
Why the interest from your father in law ?
Does he have any info he can share ?
I love my Ian May and it comes out to play weather permitting on May 1st and then stays out during the summer clocking up miles and always make me smile and i don't think i have ever seen another one whilst out riding it.
Didn't Dave Lloyd claim to have invented the compact road frame? Concept 90. Also, he learnt framebuilding from Harry Quinn and then Terry Dolan (who was himself a Harry Quinn protegé). The incestuous world of Merseyside framebuilders!
I've got an Ian May touring frame, full Reynolds 531ST. I believe it may date to 1987, based on a stamping found on a hub, assuming the wheels originally belonged to the frame of course. Mine doesn't have an IMC frame number, so I don't know for sure who actually built it, but it's nicely fabricated all the same. There's not that many of them around, especially not the known in-house fabrications.
