I bent my brand new Raceface middle ring after power shifting from the big
ring to the middle while climbing a steep riser. Crankset was a week old so
Raceface warrantied the ring. It was going to take a month to get a new
ring so I bought a steel Deore middle ring to ride with. After 2 years the
Deore chainring is still on while the new Raceface ring is still in the box.

I ain't no weight weenie or racerboy so I buy the cheapest stuff that
reliabley and safely works. Stuff will break even if you're not hard on
your bike.

Factors like cheap rings,short chain, chain mested
up,even a bad derailleur. Lets not forget bent teeth.

I did three middle rings in a summer a coule of summers ago. I think it
ended up being a chainsuck problem. The chain would wedge between the ring
and the frame and that was enough lateral force to bend it. Never proved it,
but it seems likely (and I was having suck issues then too).
