13-26 or 12-25 cassette?(4 posts)

13-26 or 12-25 cassette?skyman51

I am switching from a campy 9spd Veloce Gruppo to a Chorus 10spd. Fifty percent of the time I ride some pretty good hills. Should I stick to the 13-26 or go to a 12-25? What extra gear comes with the 10spd in both cassettes? It is a double chain ring.
great website feature at CampyRideLots

Go here to Campy's website: http://www.campagnolo.com/sviluppo.php

Look down at "Standard Sprocket Sets"; in the drop down list, it shows all of Campy cogsets in one place; you can also use it to show the relative difference in development.

I'd get the 12-25

You tell us nothing about how strong you are (how are you handling the hills now and with what gear?), or whether you do a lot of flat land riding where the 18 would really come in handy (20.5 mph at 90 rpm), or whether you are constantly spinning out the 13. How could anyone possibly recommend gearing without such basic information? Unless you really need the 12 because you are so strong (not just that you like to go down hills pedaling in a low cadence when you could go just as fast in a tight tuck), it seems like the 13-26 (13-19 straight block plus 21, 23, 26) is a pretty wide range and effective setup.
how about a 12-26 C10JohnG

Start with a 12-25 and swap out the 23-25 cog pair. Simple and very effective.

The only thing missing from this cassette is the 18.
