Not only were Leeson making 24” bikes around that same time, they had pegs on the rear wheel too! So ahead of their time it hasn’t even happened yet.
I can remember the MBUK it was featured in like it was yesterday.
My recollection of Danny starting with Inspired and riding 24, was after him riding, Leeds(?) Newcastle(?) on his pure and Dave approaching him already with that Fourplay proto. As for me, I approached Marino because I was snapping my ET frames all the time - had two back in the day, and asked him to build something similar and I hoped it’d be stronger!(it was)
