Hmm, that's bad , with that 21 i will need to pedal on most flat roads with the 52/45 chainrings

I don't think that Shimano makes a 5-speed freewheel anymore. They still offer 6-speed freewheels, and all their modern production uses Hyperglide profiling.

Otherwise, SunRace makes a 5-speed freewheel with profiled teeth (can't call it Hyperglide because Shimano trademarked that).

John, the model the OP has pictured does not have an oil port in the outer body.

IMO, a Suntour Perfect or ProCompe freewheel would provide a good replacement which can provide the lower gears. Sprockets are readily available.

JohnDThompson 

I defer to your experience with freewheel minutia. The oil port is not strictly necessary to flush out the interior. Alternatvely, you can squirt e.g. WD-40 into the gap between inner and outer bodies until it comes out the other side clean.

Ideally, disassembly, clean-up, and reassembly would effectively address the problem, and allow direct assessment of any worn or broken interior parts. But that's a task most people prefer to avoid, except err… pastorbobnlnh and a few others. The OP could send the freewheel to your "freewheel spa" for refurbishment.

SunTour freewheels are quite nice, mechanically sound, and have a relative abundance of sprockets and other parts available. I'm just not a fan of the two- (or four-) prong removers. Shimano's splined remover is a superior design.

Can't find yet a Suntour with higher range available and at a decent price. . On the website i have already mention they have a 5/6 Winner body and a decent amount of sprokets, highest i think is 26 for this body . But seems they don't have necesary spacers to build an ultra 6 for my 120mm frame. I will keep looking , other i think i will buy an Atom to keep the rebuild as much as original parts.

There are a number of Suntour Ultra 6 freewheels available right now on eBay. Closest ratio one I saw was 13-18; widest was 13-30. I think more than one 14-28 was available NOS.

The NOS versions seem fairly expensive. Used were less.

I don't know whether or not the vendors will ship to your location in Europe.

Sorin

Thank you! have seen them , they are way over my budget those high range gear, low range ones are acceptable , i mean i would 50- 80$ for one but shipping and taxed double the value. Need to find some european vendors , cause i live in the other part of the world 😅

Search ebay via the various country-specific sites, and restrict your search to that country only. Doing so for the UK shows 14-28 and 14-34 Suntour units starting at around 30 EUR plus shipping.

But perhaps better, find a bike co-op and dig through their bins...

Paul Waque 

The SunRace product has worked well for me on those hubs. It has a usable 14-28 range. The spacers between cogs are yellow plastic, cogs are chrome.

Sunrace 5 Speed Bicycle Freewheel - MFM2A on Amazon.ca for $30.

Sorin

Low chance to find them in Europe. I have wrote to the company who sell those cogs and body freewheel to see if the have spacer too. Cheers

xxcycle in France has them:

My bad, i want Suntour, not Sunrace ..., Sunrace i can find them easy but has nothing to do with vintage products imo.

Jeff Neese

You say you don't want Sunrace, but people seem to like them. Either the Sunrace that is "HG compatible" or a 6-speed Shimano HG, along with a new HG chain like the HG71, will improve shifting immensely. I did that upgrade on an old Fuji and the difference was amazing. HG really is better.

Sorin

I agree , but on friction shifters idk how much is matter to be ug...hg .. on idex shifters for sure will make a difference. I am not making any upgrade now , next time when i am ready i have a plan to upgrade all from crankset...bb...wheels....paint the frame . And i think 6 speed freewheel doesn't fit to 120mm spaced frame , just ultra from Suntour or compact from Atom. For now i am going as much as possible to keep it original . Cheers!

JohnDThompson 

Unless you're restoring the bike for a museum display, it shouldn't matter. The profiled teeth on the modern SunRace and Shimano freewheels shift markedly better than SunTour's with either friction or indexed shifting.

Sorin

Sure , is a matter of compatibility also - from my knowleadge nothing modern will fit to Normandy Hubs and 120mm frame space . We where talking about Shimano HG....Sunrace 6 speed but they don't fit? I am wrong? In the end , my options are Regina 5 speed , Atom 5 speed, Atom Compact 6 speed , Suntour 5 speed , Suntour Ultra 6 speed , Shimano UG 5 speed and maybe newer shimano 600, UG, 5 speed. Do i have other options too unless i don't have to change wheels...hubs....cold space frame& other stuff? Thank you!

JohnDThompson 

Modern 6-speed blocks are unlikely to work with 120mm spacing, but SunRace does offer a 5-speed block. Otherwise, you could re-space your frame to 126mm, install a longer hub axle if necessary, and use a 6-speed block.

pastorbobnlnh 

Sorin, if you want to preserve originality, we could probably work out what's needed for me to send you an Atom, Maillard, or Regina, that's been cleaned and serviced. Let me dig through what I have on hand here and you can PM me so I can work on a shipping estimate.
