i seem to recall my frame had a tube between the chainstays, but a double plated seatstay bridge.
Wow, yours was an ultra dope Cooks Bros one. Did the brake plate have a gap between the 2 plates? Like; one on the outside of the seat says, one on the inside? I think the real early ones didnt have any brace at all at the chainstays, but just that double brake plate on the seat stays.
"Dirt resarch"? Looks like Clives Comp3s are swinging the build back to the Moeller street comp bike.
no, it never had the plates like that black bike. it was just two plates welded together. it wasnt that early a frame tbh, i got it in 90-91 ish.
the dirt research tyres were exactly as clive described them, i'd only add the further word- 'crap'
you'd have to find some box section profiles too i just remembered!
