Gordon Taylor said:Dear All,
I am sorry that the following is a bit sketchy. However, hopefull
someone can help.
My father has as road bike with an 8 speed campag 13 - 23 cassette (It
is only a few years old). He would like to fit a wider cassette
(perhaps a 13 - 26) to help with some of the hills! However, he has
been informed that Campag. no longer make an 8 speed cassette (although
they did still have 13-23 cassettes in stock)and that therefore it would
not be possible to change it.
I was wondering if someone could suggest what options are possible and
which is the cheapest? There is also the question of whether the rear
deraileur would cope with a wider range cassette?
Thanks for the help,
Gordon
Nashbar has Record 8 speed cassettes for $39.95, before you find a 10%
off coupon. 13-26 and 12-23 size. Your current short cage rear
derailleur will work just fine with the 13-26 cassette. I shift a 28
tooth rear cog with my short cage Chorus rear derailleur.

Another option, more expensive but in the long run more useful, is to
go with a compact double crankset and its corresponding bottom bracket
AND change the cassette too. Nashbar has cranksets with 50-34 rings
for $80. Bottom bracket would be another $25. With the compact crank
alone and current 13-23 cassette, he would have a low gear of 34x23, 39
gear inches. Going with the 13-26 cassette only and using his current
crank, his low gear would be 39x26, 40 gear inches. Going with both
the compact crank and 13-26 cassette, his low gear is 34x26, 35 gear
inches. His bike currently has a low gear of 39x23, 45 gear inches.
