I need to buy a couple of 10 speed cassettes so I've been looking around online as campy stuff is difficult to obtain where I live.
Here's the ratios I could find in centaur & chorus:
They're basically the same for veloce except they do a 12-23 without the 11 cog. I don't need or want record cassettes & I don't like the quality of Miche cassettes (I've seen the teeth break).
Now keep in mind I live in an extremely hilly area... the third largest volcano in the world... you're either cycling up or you're cycling down. There's almost no inbetween, except when cresting a hill. So I'm either at the top end of the cassette or the bottom.
I have a few different needs for the 2 cassettes.
One of the cassettes is for myself and so a 12-25 will suffice. I'll be running a compact 34/50 crank with 700c wheels on one bike & a standard 39/53 crank with the other 650c bike. So a 12-25 is usually ideal. I've got a 12-23 now and find myself struggling up steep grades... so I have to avoid those for the time being cause I don't want another knee injury...
Anway, the other cassette is for a rental bike. With a standard 39/53 crank, many people find the 12-25 too tough.
Give them a triple for example and they'll often use the lowest gear of all the whole way up a climb. That's why most of my rental bikes have triples. I like to give people the option of a double, but I'm not investing in tonnes and tonnes of bikes just for them to go unused. So during the peak season, I have to make do with what I have and the levers aren't triple compatible. If I run a 13-26 or 13-29, and/or install a compact crank, I imagine they'll run out of high gears on the way down.
I'm wondering a few things:
Why isn't there a 12-28 or something similar to shimano?
If I want a cassette with a cog larger than 25, why do I have to sacrifice the 12T ?
Why they don't do an 11-21 in anything but record? (not that I could use it here, but if I lived in holland I'd be pretty pissed... you can buy 11-21 in ultegra which is pretty cheap)
Also on the subject of Campagnolo cassettes, I notice the new 11 speed super & std. record cassettes are selling for between $384.95 - $479.95
at excelsports. How many think that's overpriced for a consumable item?
(just to clarify, I'm not pointing the blame with retailers)
