i have 3 set of XTR all bought used – all of the era that was notorious for pedal failure on the Ti axle.
one set have had the left hand one ground down a concrete wall at high speed – the ends near smooth (where as an XTR should have a concave end machining on it)
i moved them to my trail bike many moons ago after that – that was 5 years ago.
i figured that with all the stories of them falling apart they should be dead by now.
ive just cursed them by writing this but that set of mines have taking serious beating.
Might change the set on my Touring mtb to the XTs though in light of all the scaremongering as im now scared they will fail.
story goes that the inner radius on the end where the “nut” is threaded to is too quick for ti.
having seen a failed set i can see how you would come to that conclusion as its the same machining on the XTs of the era but made of steel.
