Still using the cool tool that I got when I bought my first proper mountain bike in 1998 – lives in the saddlebag on my CX commuter and sees service every so often (my last broken chain was fixed with it).
Retired my c.1999 Lusso longs after they literally fell apart at the seams on way into work last winter. Suspect they had been washed too hot or something as they were passable until then. Fortunately they were unpadded so had shorts on underneath, otherwise I’d have been strolling into work on the hour at the cuckoo clock, so to speak.
EDIT – Garagedweller – still have a WTB Greaseguard headset in good condition in a box somewhere, just waiting for the right moment to be wheeled out. It’s red ano though so clashes with everything. Ace bits of kit.
