SOLD 2/10/14.
FS: Dura-Ace 7800 11x25 cassette in good shape that’s just collecting dust on my workbench. Asking $65 OBO will come with free ConUSA shipping.
Is this a custom ratio? The 7800 series was not offered in 11-25.
How did you combine the 11 setup with a 12 tooth setup.
I own 11-23 and 12-27 cassettes. I’ve been thinking of using the first 5 from the 11-23 cassette gear 11,12,13,14,15
then the next 5 from 12-27 gears 17,19,21,24,27 to make a 11-27 cluster. The jump from 15 to 17 doesnt have the teeth lined up consitently as the others. I have yet to see if it still shifts okay.
Did you have this problem?
I’ll check it again. It maybe 12x25.
It is a 11x25 configuration.
