Best freewheel 24 tooth max?

I have decided I'm going to get a suntour cyclone for my Raleigh and I am now trying to find a freewheel to go with it. From what I've read the largest sprocket the cyclone was rated for is a 24 tooth. Does anyone know if shimano makes a hyperglide 6 or 7 speed freewheel in 126mm with a 24 tooth max sprocket? And if they don't what's the best option?

TIA

I'd go for a Uniglide MF-7400 or MF-6400 freewheel, if you can find one.

FWIW, I'm currently running 26t/six speed with nary a problem on my 1st generation Cyclone. I'm pretty sure I've run 28t previously.

WHICH Cyclone? SunTour made them in three different cage lengths. S-Short, T-Medium and GT-Long.

Cyclone II short -- 26T is OK. I believe the "24" refers to the takeup/wrap capability, but even that is pretty conservative.

What has worked for me: 45-42/13-15-17-20-23-26 and 48-45-34/13-15-17-19-21-23 (just barely wraps enough chain)

I'm interested in getting a Mk I, but I haven't been able to confirm that there were three different cage lengths for the mk I. Is the GT capable of taking a 28T sprocket? If that's the case that would be great because it seems like there is actually a hyperglide wheel available in that size although I'd have to strip that deplorable paint and logo off the biggest gear

FWIW I have a Mk I short cage currently running a 13-28 freewheel with 36-49-52 triple in front, no issues.
It will wrap from big-big (if I get there inadvertently) to 36/23, which is the smallest cog I would ever think of using with the inner ring, so lots of margin for my setup.

Bikes with the Mk 1 Cyclone GT sometimes came stock with freewheels that had a 30T big cog. 28T cog is no problem at all.

I found this! https://www.amazon.com/SunRace-R30-7.../dp/B003RLE9X8

From what I've been able to find, it seems like these are highly rated. At 126mm I should be able to fit it on the bike without a problem, and with a 25T sprocket I shouldn't have an issue running any of the cyclone models.

On another note, I haven't been able to find any evidence that there was ever a medium cage 1st generation cyclone. However, I'm getting the feeling that it shouldn't be an issue with a 25.

FWIW I also have a 52mm large chainring. Not sure if that really makes a difference.

Works for me. There are three of these in the fleet.

I'm puzzled, if you're going cyclone, why not use a suntour freewheel... not to be matchy matchy, but hard to find a smoother freewheel.

That's a good question, I'll look into them. Honestly I've just seen that hyperglide is spoken highly of on this site and that was my starting point

In my experience, the Shimano Uniglide/Hyperglide freewheels shift better than SunTour regardless of what brand derailleur is used. And the Shimno units use a sturdy splined remover rather than the easy-to-damage pronged remover SunTour uses.

Sun Race adopted the Shimano Splined remover too

new freewheels adopted hYperglide style teeth , all brands.

the Freewheels using Old Tooth types are now relegated to collector status.

If You Ride the Bike, freewheels are a Consumable, like chains.

If you're handy with a Dremel, Shimano's cheapest 13-28 and 14-28 freewheels can be converted to a 13-24 or 14-24 by cutting through the rivets holding the biggest cog on.

For ref.

If you really need range, consider the GT.

On my Trek tour rig using a Cyclone -GT-, it was a simple install of a Shimano Mega-range (34t big). Swapped to a longer hub axle and spacer to get the extra high. Paid $3 NOS for the Mega-range. $15 is the going average. Ridiculous cheap and perfect upgrade for vinti types. Can cross chain to the triple from high to low, all gears usable without panic.

Need pics of the finished build but this should give the idea.

What model Raleigh? Dropout with integrated derailleur hanger?

If it uses a derailleur hanger, your'e in luck. Just get the longest type possible.

I had another bike with the beastly heavy steel VGT supported by an added hanger. That one had big range but so crazy heavy I removed it. Gave it away recently but what was I thinking Those VGT's are made for abuse. All time best heavy duty vintage derailleur.

I like the silence...

My "old tooth" freewheels ride quietly, and provide relatively smooth friction shifting. I do ride the bikes equipped with them, but it's probably only a few hundred miles per year, so they should last a good while as long as they are well maintained.

By collector status, do you mean someone will pay a lot for them?
Cheers, Eric

I would need to get a hanger adapter. The Raleigh is an early 70s super course



So you're saying the adapter will give me added capacity?

I think the short cage cyclone will take a 28, and I would go with a Suntour winner freewheel - plenty NOS in the size range you're after on ebay.

The best freewheel a 7400 series Dura Ace. The best shifting is anything with HyperGlide teeth.
