fixed gear advice

Just finished my fixed gear conversion on my Cannondale, and still working out
the bugs (see thread I wrote on re-dishing rear wheel). I am using a 15t rear
cog and 38t chainring, which seems to work quite well and is a good gear for
the variably hilly terrain here in coastal Hawaii. Only thing is I don't
automatically feel as if I am being forced to spin better (perfectly round
circles) with this combination. Should I go with a higher gear inch pattern or
a lower one to spin faster? Which will improve my spinning technique better?
Perhaps I should just ride down some of the hills around here and work it out
that way. Again, any help would be greatly appreciated.

I have been fixed gear riding for several winters now, and here is my
system: I solved the wheel dish problem by taking an old freewheel and tack
welding it shut on the back side. Space the cog you will use in the center
of the cluster and then just***the freewheel on an old freewheeled hub.
No dishing, super easy.

Gear wise, I use a 42x18 here in central Indiana, a 63 inch gear. The gear
you are using is a 68 inch gear. You will notice the spin effect more when
you use a lower gear. Simply having a fixed gear won't give the real
benefits of a fixed gear if you are overgeared. I suggest a low 60s gear,
and you will really get a workout on any downhills, but it is also a good
gear for flats. At 18-20 mph you are spinning at about 100-110 rpms.

Well, that's my experience.

Just have fun riding it and don't worry about it.  It will be a few months
before you'd notice any change.  Of course, I found that the change wasn't
particularly noticeable consciously.  I just note that I ride one or two
cogs lower on group rides than everyone and feel very comfortable.  My legs
don't seem to get as heavy and lactic-y in pacelines and the like.

I *really* stared to pay attention to the change after I began racing at the
local velodrome and would have to ride 60-80 laps at race pace on a 90-92
inch gear.

Just make sure that this cog is splined and not threaded!

It sounds as though you might have been avoiding downhills to date.
Ride down those hills and you'll certainly get a good feeling for what
the fixed-gear bike can contribute to your cycling.

Depending on what kind of hills you've got, you might find your 38x15
too low.  I generally ride a 73-75 in gear and wouldn't want any lower.
I've been up in the 180-190 rpm range at about 40mph and can't imagine
pedalling much faster.

I do ride a 63 inch gear regularly, on the once a week 25-miler my wife
and I take, but she's a much slower cyclist than me.  I've taken a 68-69
inch gear out on some club rides and found it more annoying than
anything else.  At least around here, people doing fixed on group rides
usually opt for a 42x16, which is about a 71 inch gear.

This makes me feel better about my 42x17 combination, which I've been
riding on a rail-trail in hilly ***ia. The trail takes a flat
route, so the hills tend to be long rather than steep. The gear seems
a touch high on the uphills, and a touch low on the downhills. I have
an 18 on the other side of the flip-flop hub in case I need a bail-out
gear.
