Has anyone gone large with their sram etap..........i'm talking 36, 40 or 42 cassettes and single chainring upfront. If so how is it going? what changes would you make to it?

is it for road? gravel? monstercross?.............

SRAM only rate the eTap RD for up to 32t on the cassette (with the WiFli model). Means you might possibly eke out a 34, but probably not a 36, which is two thirds of an inch larger diameter. In the photo you show, it looks like a Wolf Tooth Roadlink has been used to drop the whole RD. I tried one of those a while ago with a Campagnolo RD to see if I could fit a larger cassette. There were two problems:
  • The shifting was crap on the smaller cogs because the top jockey pulley was too far from the cassette.
  • With short chainstays it was very difficult to drop the rear wheel out, because the whole RD had been moved forward.
SRAM 11s mechanical road shifters are completely compatible with their 10s MTB derailleurs - I have a couple of bikes using Force 22 shifters with an X9 RD and Shimano 11-40 cassette. SRAM list all the compatible components here: https://www.sram.com/sram/mountain/tech ... -actuation.

My Specialized S-Works Diverge. 10-42 X01 cassette with a 44t Garbaruk front chainring. Sram Red eTap Wifli RD with a Wolf Tooth roadlink. Works for the gravelriding I'm doing :)

Maybe the shifting was crap with the woolftooth as it's for designed for shimano and not campag.......and as you say shorter chainstays.

I've used the roadlink with the etap before in the alps with a 40t rear cassette and 46/34 front crankset and it shifted seamlessly. But then my chainstays are 440mm so not exactly short.

Also I'm talking etap here and not sram mechanical as per all the information you listed, but thanks anyway

Nino Schurter was just spotted riding an etap rear derailleur with a clutch on his mountain bike. Means we may see an etap derailleur designed for your needs soon. Maybe just wait?

No point waiting for more expensive kit that may not be compatible

Jowwy: Would have liked an 11t, so 10-36 would be perfect.
