gearing problems with Bianchi XL EV2nyrider

Hi,

Thanks for reading this post. I have a XL EV2 with Daytone gruppo and I'm wondering if there's some way I won't have to continually "feather" the front derailleur when changing gears...In addition, if I'm in a highest or lowest gear in and depending on which chainring I get chain brush/slap on the front derailleur, is this normall? It ends up so I can't use the lowest gear when I'm in the small ring. Is this a set-up problem? Please help because my 18 speed has now become a 16 or 15 speed. Thank you.

You definetly need to adjust your front derailleur. Good book to have is 'Zinn and the art of road bike maintenece'. Tells you how to do lots of the basics and more. You can order it from amazon.com.

I have the Campy Daytona with the racing TRIPLE on one of my bikes. My LBS told me that Campy recommended not using the small cassete cog while in the MIDDLE chain-ring. I get the same symptom you mentioned on the front deraileur.

Since I have many more gears on the "granny" ring I can live without using the above combo. In your case It should not be acceptable to not be able to use that gear.

This small ring/small cog rubbing is common. That is not a combo that many mfgs. recommend using as it creates a severe chainline. You may be able to reduce the rubbing on the front derailleur via adjustment but more likely the noise is coming from the chain brushing up against the big ring. The big cog/big ring combo is also usually not recommended as the chainline is less than ideal. You can ride in either combo (big/big or small/small) but this can/will accelerate drivetrain wear and the excessive noise can drive you nuts.

So, yes, in effect your 18 speed is really 16 "effective" speeds or less depending on your gearing - some setups result in duplicate gear inches between the big ring and small ring combinations. But take comfort in the fact that you are not alone and it does not sound like anything is wrong. Some adjustment of the front derailleur may be warranted to reduce noise. This is usually a cable tension adjustment if it was properly set up when you got the bike.
