WTD Dura Ace 7 Speed Sprockets

[kula]

Hi, am in need of some DA 7 speed cassette sprockets to get a bike back on the road instead of being a garage queen. The 7 speed ones are uniglide which was earlier than hyperglide of todays sprockets.

Ideally over 21 teeth, but beggers can't be choosers...
Thanks

I bought some recently from Hard To Find Cycles, unfrotunately I don't know if I still have his phone number but the ones I got were NOS DA minus the spacers.

All I can find online after a quick search is this:-

Hard-to-Find is Francis Thurmer's UK mail order enterprise. The name presumably derives from the fact that it has no web presence. H2F issues an eccentric photocopied catalogue, and is a good source for offbeat componentry, including a healthy portion of fixed stuff. Unit 20, Kemps Farm, Chapel Road, Ford, Aylesbury HP17 8XG, UK

I think it is less than a minutes work with a file to make the later Hyperglide sprockets fit the older Uniglide hubs.

This is also true, just remove the larger tooth from the inside of the sprocket, though as the UG sprockets look different to HG ones I guess its just a case of how finickity you want to be about the details....

You occasionally see uniglide cassettes (although rarely the plated DA ones) on ebay. I think the top cog is threaded differently to other uniglide top cogs so a dura ace uniglide top cog would always be required. Of course you could just replace the freehub Then you can use hyperglide cassettes.

non-plated 7 speed here:

DA does have a smaller top ring, there are a load of them on ebay at the moment from SJS, think its a job lot they had kicking around but they are all ultegra ones....

If there is enough interest I might be persuaded to buy the job lot and build up some cassettes for people, there are 114 there which should enable at least 10 usable cassettes to be built, that would work out at £6 plus postage per cassette.

Post up if your interested.

I'd go halves with you if you liked. Bridgey is about half way between us so we could meet there and share out

 

[Brendan]

Sounds like a plan, do you want to order or would you prefer for me to do it?

See they are shut on a sat, what kind of bike shop is that! could do it on a friday though. Will send PM for futher details

The SJS job lot in the link Brendan posted are freewheel sprockets , not the ones for cassette hubs ( you can tell by the angled splines on the inside of the sprocket ). I would deffo be interested in splitting them with someone.
