Should I get Hyperglide with new 6spd Freewheel?
I have a Bianchi with a Shimano 600 6spd freewheel, 13t-21t. I want a lower gear (26 or 28t). I am considering buying a new Shimano 6spd freewheel (also considering used or NOS). It's currently Uniglide; twisted teeth, no side ramps or indentations, etc.
- Should I convert to Hyperglide since I'm replacing it? I wouldn't mind improving the shifting.
- If I do, is there anything else I'd need to do other than getting a new, hyperglide chain?
- Will my current, front chain rings be ok to use with the new hyperglide chain/freewheel?

I cannot answer those specific questions. I have 105 indexed hyperglide set up on an older bike and purchased a new chain, Sram 830. After mounting the new chain the gears/chain were slipping. I had to get a new 6 speed freewheel, 14/28, same as the old one. Also bought new chain rings, 53/42 on sale, bikewagon.com for $10 each. Operates as it should now.

Hyperglide may marginally improve the shifting on your Bianchi. However, there's nothing wrong with UG freewheels and often there are more gearing options than with a new 6 speed Shimano freehweel. 13-28's and 14-28's are pretty commonly found on eBay for less than $30. Just try to buy one that's not terribly dirty or worn. Alternatively, get in touch with fellow forumite pastorbobinnh (freewheelspa.com) and have him supply one that has been refurbished.

I would place cog teeth counts at a higher priority then shifting ease. having said that why wouldn't someone want a better shifting bike? The rings don't really care about the cogs. But if better rear shifting makes you want better front shifting in a time that's a different issue

Why buy a used freewheel when new shimano freewheels are available and cheaper? I believe all the new freewheels are hyperglide.

Is this a vintage road bike? Is it indexed or friction?
For "new," I would go shiny Sunrace (check ebay) or IRD.
For a beautiful road bike, I would not mount a freewheel with hideous writing on the big cog.

Vintage. 1986ish Bianchi Mondiale. Both friction and index. I use friction.
These are good thoughts. I'm not sure how I feel about the asthetic. I would have hated the thought not long ago but part of me now finds the mashup of old and new appealing. I'll consider it.

But unremovable writing on the freewheel cogs looks bloody awful, especially on beautiful vintage road bikes. There are so many other choices. Don't limit yourself to what's most popular with mountain bike shoppers on Amazon.
Shop ebay.

My primary reason is because I don't really understand compatibility. Everything I have is Shimano, so I figure it's safer. I'll checkout your suggestions.

But if you're running friction, it doesn't matter in the least.
I recently mounted a sunrace 7-speed freewheel on a bike with shimano SIS 8-speed shifters and shimano tri-color rear mech. It indexed like a dream.
The 7-speed sunrace freewheels tend to be a little nicer looking than their 6-speed models. You might need to add 1-2mm hub spacers to make it work perfectly (but not always) when converting from 6-speed.

@SurferRosa, any thoughts on this one? I also realized I would probably? need a different tool to remove the freewheel if I got something other than Shimano (I already have Shimano's tool).

^ is that a freewheel or cassette?
IRD and sunrace use the shimano splined tool. In Park lingo, that's the FR-1.
