10 Speed chain on 9 speed Dura Ace?(4 posts)

10 Speed chain on 9 speed Dura Ace?johnnybegood

I have a new Klein Quantum Race with full Dura Ace. After many adjustments my chain still rubs against the large chain ring when I am crossing from the 39 chain ring to the smallest three cogs. I don't want to cross to the smallest two, but not using the third cog creates a gap in my gearing which I would like to eliminate. My LBS has shimmed my bottom bracket 2 mm to the right, and adjusted the front deraileur several times. Still rubs (ding-ding-ding!) I am wondering if using either a Campy or Wipperman 10 speed chain would give me the slightest bit more clearance. Does anyone know if a 10 speed chain will work with 9 speed Dura Ace components? Any preference between a Campy chain with a SRAM or Wipperman connecting link or the Wipperman stainless chain?

I'm no pro wrench, however, if your chain is rubbing the large front chainring if you're in the small front and in any of the rear 3 smallest, something is wrong, no doubt about it.

Check for frame alignment, correct spindle width, correct BB installation, correct crank installation to begin with.

I've had multiple Klein Quantum Pros and have a new one myself. No such problem, ever.

I did have that problem some time ago on another bike when the BB cup started to come out of the BB. Quick, easy fix.

There is now way you should be getting chain rub on the big ring in the smallest 3 cogs. Something aint right - either your frame is off or you have the wrong length BB.
Agreed. Something is wrong.the other Tim

And I would not accept it. I don't think I would even accept a 2mm shim at the BB to correct for frame misalignment (if that's what it is). Your LBS might not like it, but if they can't fix it, they should have Klein/Trek replace/repair the frame. Why else would you buy a Klein?
