Did Chapman inherit this from his time at circle a?
That tool was published in 2010
the chart at the Chapman link is marked copyright 2009 to the guy mentioned at Blakey’s link, fwiw…
Cool stuff Pete, cheers
circle a closed down, chapman apprenticed there, i’d say he’s carrying the torch
Funny, the link with pfffffft in it subconsciously makes me think you’re rubbishing the whole thing.
oh my god
They need to update it to include disc brakes TBH.
Thank god I’ve moved to mini vees and discs, otherwise I’d now need to spend three weeks figuring out what the hell those charts mean
