my mate from over the road turned up the other day with a gt freestyle bike from the mid 90's.pretty unremarkable as far as i can see, but it did have a redline aluminium machined crank on it.i have never seen one before and it had bits machined out of the back and looked very trick.it also had a middleburn chain ring on it.i mentioned it to a couple of people and they did'nt know what i was on about.saying that they only know the racer stuff from the 80's.my mate seemed to think that they were very rare (200+ only).any ideas guys?? i'll get soem pics next time he pops over.
