I saw my dad at the weekend, and he had this with him.
It came from the coach of his old club, who told him that it was only allowed to be owned by a member or past-member of the club. Abesco is/was the club sponsor, but it looks like the frame is a Harry Quinn judging by the frame number. Nice! But apparently, he’s not allowed to respray it which is a shame; a tasty paintjob with Harry Quinn decals would set this off a treat!
He’s kitted it out with some nice bits. Check out that transmission! 55t Dura Ace time trial ring on converted Dura Ace road cranks. Sweet. I really should get a library going of his bike collection sometime, it’s fairly substantial!
