The chainrings say 9/10 speed, but I'm using them with 11-speed chain and cassette. I've never bothered about what speed chainrings are intended for, and I think it's really not an issue. Leanard Zinn at Velonews seems to agree, see https://www.velonews.com/gear/tech-faq- ... -answered/. I think that if you're getting chainsuck, that's not the cause of the problem. At the moment I'm using a Deore XT M737 crank and some old Sugino chainrings, both dating from the days of 8-speed chains/cassettes, with an 11-speed chain and cassette, and no shifting problems there. Ditto with an XTR M900 crankset (also 8-speed being used with 11-speed chain/cassette) on another bike.TheBomber wrote: ↑26 Aug 2022, 8:27amNick - what chain speed are those TA rings being used with? I have a similar setup to the one the OP is looking for - Middleburn RO1 40x30 on a 10sp bike. I had trouble finding suitable 10sp 94bcd chainrings and noted that the TA ones are only described as 9sp. Eventually I found Middleburn rings that were described as 10sp but got chainsuck problems when shifting down at the front.
The only mixture I encountered problems with was a Sugino PX crankset with TA Cyclotouriste chainrings, where an 11-speed chain tended to skate between the chainrings when changing down (unsurprising since the outer width of an 11-speed chain is about 2.5mm less than that of the 5-speed chains in use when those chainrings were designed. I fixed that problem by replacing each of the the ~4mm thick washers that spaced the chainrings apart with three 1mm thick washers, to bring the chainrings closer together, and no more front shifting problems.
