[net.bicycle] triple crank info

Here are two interesting replies to my query concerning triple
cranks.  I hope they are of use to the masses!

______________________________________________________________
It seems to me that there are no real differences in cranks in
general, except in material and styling, and triple cranks are
no exception. My bicycle has a Specialized triple crank, which
I have found to be reasonably useful. It has a 50/46/30 combination
but can take chainwheels down to 24 teeth. I have not frequently used
the lowest gear, but suspect that it'll be much more useful on a
loaded bike when one is touring. Shifting initially was a problem,
but with a change of chain to a Sedisport, shifting is quite easy.

Really not too much else to say, I like the triple because you can
have half step gearing, and not lose low gears when you need them.
I like the Specialized over the others because of its styling - thinner
chainrings compared to say, Sugino. (that's thinner in the difference
between the outside and inside circumference). Avocet also makes an
attractive one, its advantage being that the outer chainrings are
interchangable with Campy and others. The cost of the Specialized
is a bit steep at ~$114 (I think, it may be more) The Avocet is also
comparably expensive. An Ofmega triple, which looks like the Avocet
sold for $89.95 in last year's Performance Bicycle catalog.

  As I recall the only triple chainwheels with less that 30 teeth are 
either an old TA triple or a new Avocet. The old TA you could probably
find for under $100 ( though I don't have one, sorry ) but finding an
Avocet for that price will be alittle harder.
