Uniglide/Hyperglide 7

[twentysix by twentyfive]

My freewheel is dying. It's a 7 and I think it is probably a Hyperglide. I'm a bit picky about my cogs (13-17) so really want to continue to use these. So where might I find a freewheel body?

7 speed is likely to be Uniglide - does it have a lock ring, or does the smallest sprocket lock on.

Freewheel body...... you can use a hyperglide body with uniglide sprockets (but not the other way round without taking a file out to the sprockets). Your problem maybe the cones and the seals though with 'updating' - may not fit.

Options are ebay - plenty of old but new stock on there. I get my DA 7400 uniglide sprockets from the US.

Yeah - the smallest sprocket screws on to hold the others in place. That'll be Uniglide I think. I've had a quick look in e-bay. Mostly foreign sellers with postage costs to match and 14-28 sprockets (which I don't want or need). I'm thinking - end of that bike (rear spacing isn't wide enough for modern wheels and the frame is in any case getting on for 30 years old). C'est la vie

You can you get the rear cold set by a frame builder - only 4mm

Yep - cold set maybe.

But first I think I'll scour the garage for not too old screw on freewheels. Then I'll have to take the 700c rim off the uniglide hub and build it onto a screw on hub (hopefully with the correct number of spoke holes). Most of my screw on hubs have either a 27x1/4 rim (which is too big for the frame) or a sprint rim (I've given up with tubs) attached. So long as I can find a suitable freewheel I might be OK for a few more miles

Just need some warm weather to do the engineering in my unheated garage.

Well I took the spindle out today and had a look. Bit mucky and stiff so I poured WD40 and oil into it and it freed up a bit. Reassembled and off for a ride - it seems to work OK now although there were one or two worrying clicks. Nevertheless I think it'll be OK for a bit.

Jolly good. You can take the freehub off using a 10 mm allen key, give it a good soak, and maybe add some light oil. Then shove back together and grease the hub bearings.

I've got at least one 7 speed freehubs that might be serviceable ? It was skipping a bit, but might need a lube. Can check at weekend if of any use ?

I think I've still got a new ultegra uniglide freehub if it's any use.

Ooooh Thanks WJ - Yes please . I'll PM you with my details.
