| 1994.1 | start with just the chain ring | MATE::PJOHNSON | | Fri Jul 12 1991 17:02 | 7 |
| You can just replace the chain ring. I'd recommend round rings instead
of Biopace. I'd also recommend getting a bike repair book. There are
several notes in this conference about which bike maintenance manuals
are good.

| 1994.2 | If you don't go al the way it might skip | SMD72J::MCCAULEY | | Fri Jul 12 1991 23:35 | 6 |
| You can try not changing the freewheel. you will know soon enough if
gets you by, because you will get skiping on the worn cogs. July's
issue of "bicycle" mag. has a article on drive train maintenance.
the book advice from reply 1 is also a very good idea.

An old chain on a new chainring will almost certainly cause
"chain suck", where the chain wraps up around the bottom of the
chainring.
One reason that your chainring wore out is probably that your
chain got elongated. When the chain stretches, instead of all the
engaged teeth driving the chain, only the 2 or 3 at the very top
of the chainring drive it.
The chain is the part that wears out most frequently in any bike
transmission. If you don't replace the chain with the chainring,
your new chainring will wear out more quickly. Try these two
parts first. If it seems to work fine, leave the rest alone.

| 1994.4 | Might have misread you 1st time | SMD72J::MCCAULEY | | Fri Jul 12 1991 23:48 | 4 |
| Regarding my .2 reply ---- thats if you go with a new chain & chain
ring. just changing the chain ring won't effect the freewheel

| Whether or not you change ANYTHING else will depend on the wear and
(or) miles on the stuff. I say miles because some "miles" are worse
than others. Some folks can get away with 3k-5k on a chain. I usually
end up replacing mine every 1500-1800 or so... The last time I had
1600 miles and the thing was stretched 1/4"...
Only you'll be able tell. And probably during the first test ride.

| On the bio-pace c/r's...
How does the positioning of the ring in relation to crank arm position
affect pedal stroke performance, or anything else for that matter?
In other words, if you take of a bio-pace chainring and rotate it,
say, 45 degrees, then put it back with the crank in the same position,
what happens differently?

| 1994.7 | APEX'S & ELIPSE'S (GREEK) | WMOIS::C_GIROUARD | | Mon Jul 15 1991 13:13 | 7 |
| You loose the advantage (whatever it is) of having the apex of the
elipse positioned through the beginning and end of the down and
up stroke -- I guess this is position is where the majority of
torque is generated through the pedal cycle. At least that was the
concept...
