Chain rub on a triple - to be expected?

It's great that you are wanting to learn more about your bike and how it works!!! I only wish that more people in general would take that stance!

As for your bike, it indeed you have Sora shifters, then you're right you do NOt have trim with your front derailleur... that starts with the nine speed drivetrains. But learning not to cross chain is always a good thing, and there are many areas where there are duplicate gear(gear inches) without having to cross chain.... I'm sure tthat your bike shop will be glad to show and explain that to you.

Ahhh, so another thing to add to my list when I upgrade my bike in a year or two...better shifters! No trim with Sora...bummer! As I find more things about my bike that I'm somewhat dissapointed in, I'm thinking it will be more like only one year until I ugrade. But you have to start somewhere. This bike is getting me around just fine and I can beat the poor thing up a little bit and not feel too bad about it.

I still think a trip to the LBS may be in order. But I think working out better gear combos to avoid cross chaining is going to help. What would really help is if my legs were stronger so I didn't need those granny gears so much. But I know they're getting stronger, so it's probably just a matter of time.

I'm plenty strong and I still use my granny gears - A LOT!

It's all in where you ride.

Today my friend and I rode up Iron Mountain Rd. near Pollock Pines. Talk about needing your granny gears!!!

Based on the info and advice in this thread, today I tried changing chain rings more often to avoid cross chaining, and it worked great. I probably switched rings 8-10 times and didn't drop the chain once. Much better. Less noise and chain rub, and better gearing performance in general.

Probably no snow though. Iron Mountain is a beautiful ride.



This was two years ago.

You're right...no snow this year at all! Very beautiful up there today...but very dry already.

Hey, I see a Placerville Bike Shop jersey in that photo!

That's Yellow. She lived in Placerville before moving to Utah. I'm in the red jersey. SadieKate is the other chick. The really tall guy is Bubba, SK's honey. The other guy is Ed, who also lives up there. My honey took the photo. He was doing SAG for us since he had broken his arm mountain biking on Tam.

My Specialized Allez Elite was converted from a triple to a double when I bought it. Since then my LBS has looked at it a few times but can't manage to get rid of the rub when I'm in smaller front ring and smalls in the back... I get incredible rub that no amount of shifting or partial shifting can get rid of, consistent through 4 or so gears. The guys don't seem concerned, but they cater to racers on Pinarellos who laugh at my Ultegras.

Tell me that the rub *can* be tuned away?
