I am in the market for a new bike in the $500-$600 range. One of
the many subjects about which I am ignorant are the relative
advantages and disadvantages of elliptical and round chainrings.
I'm told that the elliptical rings provide greater acceleration
because they provide mechanical advantage through leverage. They
also tend to be more expensive, however. Although I notice a
difference between elliptical and round, I haven't been able to
develop a preference in my limited test riding. Are the elliptical
rings worth the extra money? Holding all other factors constant,
what sort of time advantage would they offer a reasonably competent
rider (my objective) in a 25 mile time trial?

| 1196.1 | This has been discussed -- here's a summary | CESARE::JOHNSON | Me? Opinionated? | Tue Jun 06 1989 12:34 | 14 |
Check out notes 441 and 685. I think I can summarize what's been
said so far:
MTB riders -- Most if not all consider these de rigeur.
Road Racers -- Mixed opinions
o Some concerned that it hurts their spin (100 rpm plus)
o Some convinced that the small ring helps in climbs.
o Some complained that the elliptical rings can cause a dropped
chain under race conditions.
I think an honest answer to your question about time advantage in
a TT is ZERO. The choice is simply a matter of style/personal preference.
