Front Derailleur area noise.

I have a "Breezer Radar Pro bike that I bought a few months back. I love the bike except for a lingering noise that only crops up if I am climbing out of the saddle or sprinting hard. To me it sounds like the chain rubbing on the front derailleur (it is an Shimano FD-T6000). Other than this the bike is smooth and everything is quite functional. This is my first bike with SRAM shifters, . On my older bikes I could just feather the front derailleur to keep the chain centered. I have tried looking down when the noise crops up both climbing and sprinting and I cannot see any flex or movement in the chainring area. It is a threaded bottom bracket so a bearing is not high on my suspicions but possible. ??? I have a good bike shop that I am planning to take it to if I cannot figure it out myself. I bought the bike at "Performance" which is a ways from home and feel like leaving it for a week to not have the problem corrected. sooo....... Any ideas out there?

One of the costs of indexed ft ders is the reduction of trimming, SRAM is particularly at fault in this. Their solution is to sculpt the ft der cage just so. But many feel this is a poor substitute for proper trim ability in the shifter.

As the control cables and casing wear in the ideal positioning of the ft der cage suffers. Has the bike had it's, hopefully, free initial service yet? Andy

Yes, I have taken it in twice, everything gone over, the bike mechanic seem very good but overwhelmed with work. I may be at fault for not properly describing the noise. I notice on the new derailleur how narrow the chain guide is. Maybe raising or lower the entire thing. I am planning a trip to Velo Republic bikeshop next week anyway. Thanks for your help.

Just out of curiosity where do you find room for all of your bikes. Not a bad thing by any means.

My wife tells me I have too many bikes... Garage, the bike room (converted breezeway) and the attic. Bikes in progress are in the basement. Andy

Forget that - what about time to give each bike enough saddle time that it does not feel neglected, while keeping your wife happy as well! (I initially constructed that sentence a little differently, but thought better of it)

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!

My Campagnolo 10-speed indexing allows trim on the front derailleur. The Front has multiple clicks so chain rub can be avoided.

So your new bike has SRAM shifters with a 10 speed, 3X front derailleur?? That doesn't sound right.

No it is a 2 x 10, it has 48/32 chainrings on the front and a ten speed cassette.

I like that yours has fine adjustments to remove chain rub, I am changing the front chainrings to 42/28 next week. I will ask if there are any options with SRAM for dealing with this annoyance. All I have ever had is lever shifters so this is all new to me.

Post a pic of the FD. The model you listed is a 3X.
