Campagnolo Record triple c/s question .

[bagpuss]

I have a square taper Record triple 10 speed 50/40/30 rings are also marked as ud in red {ultra drive?}135 bcd .
It has alloy crank arms,not carbon.
What replacement outer chainrings can i use? I would like to go to 46 teeth ie a TA .
I am told the off set of the campag will not work with a TA 135 bcd chainring.
Has any one here had this problem ? Did you find a work round?
This site seems to open a can of worms.

I'd just buy a set of TA ones from Spa. They have a screw-in anti-jam pin that goes in the appropriate hole for Record (concealed 5th arm) or the others.

A little worry would be how good the shifting would be from 40 (or 39) to 46 - it's fine with 48 for sure (like mine). The front mech may need to be a little high to stop the cage hitting the middle ring. I've run 24/39/48 no bother with a Centaur 10 speed triple front mech and chainset.
