Update : Attempted Shim9Ergo11 route with LBS help.
LBS person #1 (owner) looked at the CTC link and was happy give it a go and it was booked in for the operation.
I brought it in and LBS person #2 was there, he was non-commital it would work but would do it, so I left my bike there, a little aprehensive now, thinking I might have made a mistake and should just try to do all this myself.
Later in the day I picked it up and was served by LBS person#3 , when I asked, he said 'well as well as can be expected for non-matching components' with no positive vibe which was really a bit of a downer.
Fortunately I managed to chat with LBS person #2 on the way out of the shop , he was alot more positive and actually seemed pleased how the whole operation went. That cheered me up a bit.
Finally, I managed to take the bike for a ride today and would like to report it shifts very well -
Although it feels stiffer compared to say full Chorus shifting, the ability to execute multiple ups and down shifts is a bonus.
Here are some pictures.
Ergo 11 Right shifter.
Shim9 RD and Cassette - (no Shiftmate required for this combo)
Shim FD - (so happens the FD and Crank are the last original bits from Tiagra groupset.)
Happy with the LBS for being willing to do the job, as well as the results.
And err.. yes, I can now shift between Big and Small Chainrings too!
Thanks for the encouragement Matt.
Thanks for this link as got a project in the pipeline and dont like Shimano 7800 series 10 speed shifters
