To all Bob Jackson owners....

dogsballs the ones i've ridden are very very flexy through the BB area, PJ's moves out 1cm side to side when you track stand. saying that my dave yates in 531 moves around a bit as well. modern 531 isn't as good as old 531, or it could just be the lugs/BB shell?!?

it does flex, that's why it is so lovely and rides like a dream, but possibly is not as extreme as dale thinks, but then again, he doesn't know what a vigorelli is so i'd take his anitpodean opinions with a pinch of salt. (joke) It's a 57/8, i'm 6" 2, it fits perfectly and because of the horizontal top tube they come up big. Dave is right, Momentum is wrong. if you come to polo on sunday you can have a go.
