Hey guys,

I'm aware the following question can come down to "it depends on the bike" so sorry if there is no real answer to this...

I want to put an 11-36 cassette on an Emonda SLR with a Long cage Ultegra mech and a compact chainset. Basically the need is for a lower gear on the hills. I have seen people run an 11-32 cassette on a short cage dura ace mech, and the long cage mech is really designed to add 4 teeth to the chain wrap right?

The other issue is of course will the jockey wheel clear the cassette....

My other option here is going to be ordering a 46/30 chainset from Sugino. I don't have the bike yet, and it's not due for another 30 days but I really need an answer before the order is placed.

So the question is... can it be done? have you done it?

I did ultegra RD-6800 med cage on 11-36t 11sp cassette on 2012 madone 5.2. Upper Pulley 10t, and longer B-screw.

Or you may use wolf tooth roadlink.

My long-cage 6800 had no problems shifting a 36t cog without mods.

Roadlink and smaller upper pulley are both good ideas if it doesn't work.

34/32 can be too high for steep gradients if you're not going very fast and want to maintain a high cadence.

I also think road gearing is flawed and I believe 95% of riders would be much better served with a set of 46/30 chainrings.

And 99% of all statistics are made up out of thin air...

I kind of agree with this, depending on where you live of course. Do you know many cranks that will fit modern road bikes in 46/30? I am only aware of the ones by Sugino

I whole heartedly agree with this. I have an old White Industries mountain bike crank that uses 94mm bcd on the outer and middle rings. By leaving off the inner ring and spacer, I can use it as a double crank. Stronglight sells a 29 tooth ring for 94mm bcd. TA and Stronglight sells every even tooth from 50 to 30 in 94mm bcd. I do not know if anyone currently makes a 94mm bcd crank anymore.

Ever heard of these things called 'triple cranksets?' I use 26/36/46.

I only know the Sugino cranks, and maybe some specialty stuff like White or Rene Herse that you wouldn't want to have on a "normal" road bike. Sugino is expensive and heavy unfortunately.

Triple cranks are a) a nuisance and b) unnecessary with modern cassettes. MTB cranks have a bad chainline and Q-Factor.

The currently "best" solution is going 1x with a 10-42 cassette, but the looks, price, XD driver requirement and gear spacing also make this hard to swallow...
