11 Speed Shimano Ultegra shifters. Does it work with 11 speed MTB cluster?

[RABUBI]

I built a Gravel bike using my hardtail MTB. Groupset is 11speed Shimano.

I then took an 11 speed Shimano Ultegra set of Shifters, but cant seem to get the gears dialed in.

seems the indexing is totally different. 

anyone did this and had any luck?

What is important is that the rear derailleur and shifters match, the cassettes are compatible. Shimano uses a different pull ratio in their road and mtb drivetrains.

You probably need one of these. I have one using road shifters and mtb derailleur and gets them talking nice to eachother.

10 and 11 speed shimano road shifters don't have the same pull ratios as MTBs. This was created for this very issue:

Most older 9 speed shimano stuff is cross compatible though.

very good explanation here:

My LBS built up a bike for me and put one on. Maybe try get your LBS to order you one through www.paragontech.co.za

Nick, we (myself and LBS) have mated 10 speed Tiagra hydraulic road shifters to XT derailleur and gear cluster on my Procaliber hybrid. Works perfectly. No tanpan required in that case.

Edit: I haven't really used the bike much since the conversion was done. I took it for a spin yesterday. Looking down at the rear derailleur I saw it now reads 'Tiagra' My apologies. My bike shop was smarter than I was....

Oh, interesting. Tiagra 4700 is unique/different from all of the other shimano 10 speed stuff, and can actually be used with some of their 11 speed (Road) stuff and is aslo completely compatible with GRX range of 10 speed. As to mtb, I had no idea that would work.
