I'll be "dumbing down" my Challenger to make it more period correct.
New School Skyways to be replaced with Arayas rims/GT Mohawk hubs.
dialled bikes bars to be replaced with Challenger bars.
Shimano brake lever to be replaced with whatever will work with a Pitbull.
Crupi Beartraps to be replaced by Shimano DX (if I can get them re-furbed).
After that, everything on it (apart from the headset) will be late-80s/early 90s stuff.
