Opened this thread thinking “I should do quite well here”, then started reading some people’s posts, and then remembered since I got rid of all my old M952 XTR shifters and mechs to go 10spd, I’m not quite in the ball game any more!
Had a set of original 4 pot XT brakes on main bike until a year or so ago too, they would have been 12 years old when I sold them!
Oldest part on my main bike now, in constant use, would be the ODI lock on grip collars. Think I’ve had them since 2004. Do own a set of Easton Flat boy pedals that still get used from time to time that I bought 2nd hand back in 2003 and are still going very strong! Rear disc rotor on my hardtail must be quite old too, can’t remember buying any 160 6 bolt Shimano rotors any time in the last 7 or 8 years.
