9100 50/34 to 50/36

Anybody swap their Dura Ace 9100 50/34 for a 50/36? Essentially just change the 34 to a 36?

I use a 50/39 on a couple bikes. It works great. If I ever bring either of those bikes to a hilly area I’d have no qualms about a 36. More likely I’d just go back to a 34.

Anyway, I doubt very much that shifting will be negatively impacted and the smaller difference in chainring size is pleasing while riding.

All I meant to say is that Shimano says it's not optimal.

It isn't.

...but... you can make it work acceptably with a little fiddling

Ayup, plug and play..grease on CR bolts...Fd doesn't care and the 'ramps' gig, matching, is overplayed.

Agree on all counts. Mine works fine.

I also installed a 46-tooth ring on my Indy Fab. Works flawlessly.

The grease on the bolts is a good idea too. I had a creaking 5800 crank last summer. Took out the bolts one by one, dabbed a spot of grease on them, reinstalled, snugged them and enjoyed blissful silence.
