Uniglide shifting?
LAWunder
understanding is that they have shaped (twisted) teeth but no shifting ramps;
is that correct? Will shifting be smoother than with a Suntour Perfect
freewheel with unshaped teeth? How much smoother is Hyperglide than Uniglide?
(I've ridden with a Perfect freewheel and with lots of different Hyperglide
cassettes, so I'm trying to get an idea of what Uniglide is like in comparison.
Also, do you have to use a Uniglide chain with Uniglide cassettes, or will
SRAM/Sachs or Shimano HG chains work fine?
Thanks for your input.

Uniglide set the standard for smooth shifting in its time. I still use my
7-speed Dura Ace SIS uniglide freewheels. Hyperglide was aimed initially at
mountain bikers, and was supposed to be an improvement when downshifting under
load. Uniglide chains are almost impossible to find anymore, but don't
worry--uniglide cogs work great with any narrow-type chain. I like Shimano HG
chains, even with the special pin, but I'm not one of those people who takes
the chain apart every few hundred miles to sterilize it.

Uniglide shifts nicely, a properly adjusted bike with Uniglide will be about
like Hyperglide.

My road bike has a uniglide freehub and cassette. I don't notice a big
difference in the shifting on this bike compared to the rest of my bikes
(which have Hyperglide cassettes). Hyperglide probably shifts better
under high load, but I rarely shift under load on my road bike.

I use SRAM chains on all of my bikes, including the Uniglide road bike,
with no problems.

If Sun Tour is a 5 and Hyperglide is a 10, Uniglide is 6 1/2, maybe 6 9/16.

Any 3/32 chain will work fine. One unique advantage of splined Uniglide
cassette sprockets is that they are reversable, so when you wear out one
side, you can just take 'em of & flip 'em over.

...if you shift well, that is without much load on it. I'm running
UG on my road bike and it's working nicely, but I prefer HG on my
tandem where shifting under some load happens often. Shifting UG
deliberate under load shows the difference...

I will check this out when I ride to work today. My impression is that it
shift quite well under load, though I wouldn't use it on a MTB where I was
climbing in a 22 inch gear.

So I tried shifting under a load. Conditions: 6% grade, unhill, starting from
a dead stop in a 46-14 gear, shifted a cog at a time while standing up to a
46-21 cog.
I was surprised how well it worked. Not as smooth as Hyperglide but as quick.

Aiiee, if I found myself at a dead stop on a hill in a 46-14 gear, I'd probably
be walking the rest of the way up. Seriously, thanks for doing the experiment
and reporting back.
Overall, from the feedback it sounds like Uniglide was a pretty good system.
My thanks to everyone who responded; I appreciate the help.

ok, I'll compare them again this evening 8)
