No. None of the cassettes you mention are worthwhile for me or many other people I suspect. When I
need a low gear, I need a low gear. Otherwise I prefer evenly spaced usable medium gears.
The brand new for 2004 14-28 Campagnolo 9 speed Veloce cassette has 14-15-16-17-19-21-23-25-28 cogs.
My custom cassette is 13-14-15-16-17-19-21-23-28. Why would I or anyone give up a usable 13 cog for
a rarely used extra low gear in the 25 tooth cog? Why do you need a low gear in the 28 tooth and a
pretty low in the 25 tooth? Why not just get a low gear and more usable gears? By starting with the
13 as the small cog, I can actually use the 14 tooth cog with the inner chainring. I would be very
unhappy if my highest gear was restricted to the 15 cog as with the Veloce 14-28 cassette. And I run
a 42 chainring. Those running a 39 chainring would quickly run out of usable gears on the inner
chainring with a 39x15 as the high with the Veloce 14-28 cassette.
As for the Marchisio combinations, the 13-27 has no usability. My 13-28 custom has a more useful 23
cog than the 24 cog in the Marchisio. And my 28 cog is lower than the 27 cog in the Marchisio. I
don't know why anyone would buy this 13-27 combination when they could get my 13-28 custom.
The 14-30 would be useful if I wanted lower gears. The 30 would be nice occassionally. But to get it
I have to sacrifice the 13 and replace it with the 27. I would end up with two or maybe three low
gears if the 24 tooth is counted. I only really need one low gear
(28) on a road racing bike, not two or three (24-27-30). I would have to sacrifice several medium
gears on the inner chainring with the Marchisio 14-30 cassette.
I think of my 13-28 custom cassette as a half step plus granny for the road racing bike. Plenty of
closely spaced useful medium gears and the granny gear of the 28 cog.
