RABUBI Posted October 11, 2021 Share 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?

Knersboy Posted October 11, 2021 Share 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. 100Tours 1 Link to comment Share on other sites More sharing options...
peepeekaitjie Posted October 11, 2021 Share https://www.wolftoothcomponents.com/collections/components/products/tanpan You probably need one of these. I have one using road shifters and mtb derailleur and gets them talking nice to eachother. Link to comment Share on other sites More sharing options...

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....

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. Link to comment Share on other sites More sharing options...
