Campy 10 shifting question(7 posts)

Campy 10 shifting questionPaulCL
Apr 26, 2002 9:30 AM
Why is it that my Record 10 shifts like butter while in the work stand, but shifts like crap under load??

Here's the deal: Workstand great, on the road, in the big ring, the shifting is horrible between the 14 to the 19 cog. It won't shift or it will overshift. Mostly it rattles until I ease it into gear. A real PIA.

On the workstand, I've adjusted cable tension so that, while in the big ring, it shifts beautifully. Then onto the road...crap... I'm no great mechanic, so any suggestions will be greatly appreciated.

Thanks. Paul

No obvious reason for what you describe.

Is this a new build??? If not, has this shifting problem just spontaneously come upon you?? Crash???

A couple of suggestions:
1. Make sure the BB cable guide is scrupulously (sp) clean. This will require an old toothbrush and some cleaner.
2. Use the barrel adjustor on the headtube to tune the shifting WHILE you're riding. Only takes a fraction of a turn!!!
3. Is your der hanger bent???
4. Old or ratted-out rear der cable???

You may have to replace your rear der cable. ??? Make sure the cable is on the "lower" side of the der cable clamping-bolt.

good luck.

every time i take my bike in for a service i have to adjust the derailleur slightly afterwards. must be something to do with the extra load when riding which you don't have when it's on a work stand.
dont move the barrel adjuster more than half turn at a time. its v. easy.
New cables tend to stretch a bit initially. (nm)Leisure

Did you replace that to? I usually replace my rear derailleur cable and housing every 6 to 8 months to keep shifting smooth. The other cables get replace every other year or so, as they are less critical and sensative to cable condition.

If the der. is truly adjusted properly, the cables in good shape and seated, chain and all pivots (including inside Ergo levers) lubed properly, then there is only one other possibility: alignment. Your hanger(hopefully) or your frame. A good shop has the proper tools to check for you and usually won't charge anything for just the check as it only takes a couple minutes.
