@hannawald -

the general consensus is the extralite rings don't shift well with anything. When I switched to etap, I went to praxis rings. Cannondale's MK rings are a lighter option if you can find them - they're supposed to work well. KCNC cobweb rings might also work well. After my experience using extralite rings for several (almost 10 years), I wouldn't go back to using them with any drivetrain. They're too inconsistent and it doesn't justify the weight savings.

Thanks, their weight was tempting but not at the cost of function..
A friend of mine recommends Stronglight with ceramic coating..50t chainring is 80g claimed. But not much experience shared here. From eshop reviews they should be ok..

Just installed a set on a sram red groupset and it shifts very very very well. I'm getting a set for my bike too.

I think it depends on what you come from. If you're used to shifting with great chainrings (ultegra/duraace/etc) these might disappoint but if you come from medium quality they might surprise. We used truvative chainrings (sram rival/force) before the extralites and the extralites are much better. We will stay with extralite.

Have you still been having a good experience with the Extralite chainrings? Are you on the RC2 or CH2?

I've had two sets and they've never shifted well. Either risk chain drop or rattling as it struggles to shift up.

MKV rings work very well, particularly with Di2.

Thanks Ryan, I'd be interested in testing those out. The trouble is sourcing the 50T MKV rings. I haven't seen them for sale in maybe a year. Just posted something in the WTB section, hopefully someone on here has some for me to test.

Compact 50/34 rings (rc2)

Just tried them with etap and they didn't work at all.

Also I don't think they work for people that are used to push during shifting. You need a firm long push on the shift lever into a properly set max limit to shift reliably. I'm dialing in the max limit in extremely small increments to find the balance between fast shifting and no chaindrops.

So I think they are for mechanical only and for riders that have good shifting habits. Then they work pretty darn ok.

If you want a light ring for etap maybe try Carbon-Ti carboring. Those rings have even more pins (titanium) than sram originals so maybe you can shift from any crank position.

I have some extralite (MC) in route to me from r2-bike.... I have praxis buzz ready to go... MKV rings are too hard to find. I was trying to be a ww on my BMC Aero build

Asked local Cannondale dealer of the MKV rings, they said these are "old", "out of stock" with Cannondale and implied they're not manufactured anymore.
