” I ended up having to pump them up so hard to stop the pinch flats they felt utterly horrid”
I believe the minium pressure on at least the older and not quite brand new (speed king/mountain king/etc) is 50psi. Not sure about rubber queens and newer, or anything black chilli
Continental tyre tread ‘caving in’ from underneath, tread then folds over each time it hits the floor. Seen in on speed kings, mountain kings, verticals, gravity. All non black chilli?
Continental tubes claiming to be suited upto 2.5″ tyres. Way Smaller, thinner (and pinchflat prone) than Specialized upto 2.2″, Raleigh upto 2.1″
Horrendous with any tyre anywhere near a small 2.5″
’04-’07 XT and ’05-’08 LX aluminium chainrings. Completely dead rings/chain/casette inside of 7 months through summer, inside of 5 through winter
Magnesium rocker links maybe. I’ve read in relation to bikes (so not sure on how different/all magnesium alloys actually behave in reality) magnsium has a very low fatigue resistance. Rockers pinged off inside of 3 years. Split showed the crack had been propagating for some time with loads of tiny cracks up until the final break
‘Professional’ tools, appear blackened/hardened, T-25 head trying to round on first use
Non-servicable freehubs? Lock up mid-ride or snap (loud crack) and go free without warning
Bontrager ACX TLR 55/62a, tread starting to cave in from underneath after about the 3rd ride
Oddly my Bontrager MudX TLR 55/62a (visually very similar tread) haven’t done this whatsoever. Still going strong for the 3rd winter, admitedly not quite as tall tread as when new, so on 2nd bike that doesn’t see the deepest of winter
Any bike with Maxxis 2.25″ supplied on Mavic XM317 rims, presumably with ‘standard’ XC tubes?
[cough]orange[/cough]
They’re pushing it on XM719s IMO/IME. On XC717s 2.25″ maxxis is very squeezed at the rim. Sub 50psi was pinchflat central for me with standard tubes (which don’t seem to have met the tyre until you’ve inflated to about 20psi)
Older crank brothers multitools. Rounded about half the tools on mine far too easily without really trying
A friend had a set of Crank Brothers candies undo/empty the ball beatings out on the first ride
Can’t think of anything else off the top of head right now
