That's why I don't wear bell-bottoms you hippy
It's hard to see in this pic, but I just used a piece of old rim liner (or inner tube w/e) between the spring and the Dtube to reduce chafe;
Ya prolly know this, but run yer safety wire through
the middle of the spring to both loops. This way should it just be a hook that lets go (usually what happens) - you still have the spring and can rebend a hook
Ofc... I've still not followed my own advice meh - watch as I loose a spring on my ride to work today lol
edit: a very neat and tidy solution with some shrink tubing (and far more than just mere safety wire no less lol);
more good info on exhaust systems using spring retainers;
