Did I imagine it or did problemsolvers make a pulley to convert newer bifters to mtb cable pull?

Wolf tooth tanpan and roadlink have me rolling on a 11-40 XT clutch and Ultegra shifters.

Very similar setup here - although only 11-36 and no roadlink - feels like it was meant to be! I ran an 11-40 for a ride and it worked but moved that back to the mtb as need it more there!

If your starting from scratch then SRAM do this off the shelf.....

The cable pull being the same for road and MTB on SRAM

Cheers, thats just what I was after.

As for SRAM, yes I believe it does work off the shelf, but I have shimano on my other bikes.

Although thinking about it I have a set of crash damaged 7800 levers, so I might canibalise them and an old 9s mech which would give me 11-40 with the roadlink and an expander cog?

Good question. To cover myself I'll rephrase my statement

With SRAM you can buy a road shifter and mech capable of running 10-42 cassette

I'll do a bit more research later

This also suggests its all 1:1. What am I missing?

I think everything up to 11 speed road is 1:1, 11 speed mountain is something like 0.8:1, so you need a special mech to do 11 speed road shifter with 10-42.

Ah, it's called 'x-actuation'

Thanks I get it now. Upto 10 speed SRAM is mix and match

At 11 speed the difference is that SRAM make a CX specific rear mech that will work with a 42 cog and road shifters
