Need help with "gear trimming" feature on Ultegra triple(5 posts)

Need help with "gear trimming" feature on Ultegra tripleER
Jun 24, 2003 6:34 AM
My girlfriend just got a new road bike with a triple chainring on the front and she does not like how the "gear trimming" feature is set up. Right now, it takes two audible clicks to go from the smallest chainring to the middle chainring, and it does this very sloppy, sometimes it does not even go in. But when going from the middle to the largest chainring it only takes one click. Is there a way to set it up so it takes only one click to go from the smallest chainring to the middle, and then have the gear trimming feature used only on the largest ring, I have a double on my road bike and I have my gear trimming set up on my largest ring, and mine shifts very well, I should mention that both bikes are with ultegra
Thanks in advance.

STI triples can be a "bear" to get set up properly. When I set up an Ultegra triple, I end up with one grannie gear position, two for the middle ring and one for the big ring.

I agree with the above post- the trim should be for the middle ring. I have my Ultegra triple set up this way and it works very well, I was really impressed because I can use all 9 cogs in the middle ring without any rubbing. Triples tend to cause some chain rub up front without this trim feature. Adjust it so that one click puts the chain on the middle ring (barely), and the second small click just allows you to ride the smallest cog in back without chain rub, and the third click puts you in the big ring.

I have my triple set so that (moving from inside to outside) the second "middle" click puts the outside of the cage directly above the outer chainring. Works great, no rub!
You can get it working pretty good maybe a bit of custom bendingBarnyard

and playing with your barrel adjuster if needed. But how you like your front derailleur can be a personal thing.
