It is Dave Roper. In the full size shot you can see the name Dave beneath the white bib and a luxurious moustache. Admittedly hard to see in the smaller image. This next pic is one of my all time favourites. No elbow on the floor or front wheel five feet in the air, but that sky...It looks photoshopped but that's how it came out at the time. I've tried to recreate it since without the same level of success. So, who is it?
Background sky from Signpost is great, was fortunate to grow up living on Birch Hill estate just off Signpost in the halcyon days of early morning practice and that backdrop was fab at 4am summer time when it didn't really get properly dark .... Is it Nathan Harrison ?
You're correct with Bret Crossley. I googled him before I put the pic up as I recall him having a bad one but couldn't remember what happened. Turns out he's now a paratriathlete and a good one too by the look of it.
