M780 XT triple rings

[oldave]

Middle ring on my newly acquired 2012 BMC Trailfox carbon bouncer is worn. Replacement difficult to find - and expensive!

Would a lesser quality fit/work acceptably for my tow path excursions:

Shimano FC-T521 10 Speed Triple Middle Chainring, 32T-AE Black

Expect and excuse forthcoming questions....this thing has hydraulic disc brakes and other modern stuff about which I know very little.

Thanks.

Pretty sure I have a new middle ring in my collection. May even have a full set of nos triple rings if you want to refresh the whole lot too.

^ Thanks. Certainly interested in middle, all 3 depending on price! Paid a modest 380 quid for complete, all original, vgc, bike, so don't want to go too OTT on spares.
PM me?

TA or Stronglight rings from Spa Cycles will work every bit as well and last longer.

^ Thanks, hamster. Had browsed Spa but not a lot in 104 4 arm 10 speed.
At only £13.65 the one referenced in OP probably best bet.
Longevity not an issue - only a few '000 miles spread over a number of bikes about all that's left to me!

Hectic week, catching up on admin. Here's a few pics of a couple of sets of triple rings I have. Top are nos xt, never been fitted or seen a chain. The lower set in pics is used, by that I'd say new take off. They've seen a chain but briefly as literally no wear. They aren't xt, can't remember what cranks they came off, maybe slx as I've had some in the past I swapped over to 1x, maybe Deore, though I don't recall owning any Deore cranks of this era. Middle ring is same as xt.

I do also have a new middle ring somewhere in another box, probably with my m970 spares as they also run the same middle ring.

I seem to remember that there are tabs on the spider that get in the way of certain makes of chainring when fitting to a shimano crank

Just make visual check over first, compare the rings side by side, make sure nothing sticks out

Thanks for your time and trouble, Ian. The non-xt set would do fine - all depends on price! Very much OAP budget at moment, so if you can let me know I'll decide v quickly.
Rgds, dave.

Thsnks. My thoughts also, why I haven't just bought a 32T from e.g. Spa.
