WTB: Shimano 14T or 15T 2nd Position UniGlide Sprocket FOUND
FOUND A 14T SPROCKET ON EBAY
EDIT: Further research, these were only used on Dura Ace Uniglide freehubs. I'm looking for a 14T or 15T Shimano DURA ACE 6, 7 or 8 speed "twist tooth" UniGlide 2nd position cassette sprocket, the one that goes behind the screw-on sprocket. These came in 2 styles: Type 1 with the the splines on the rear, towards the hub and Type 2 with the splines on the outside face. I need type 1. https://cimg7.ibsrv.net/gimg/bikefor...8c07e050ef.jpg Here's a 15T for use with a 7 or 8 speed UNIGLIDE cassette and freehub. https://cimg5.ibsrv.net/gimg/bikefor...2ed04513d5.jpg These 7-8 speed UNIGLIDE sprockets are 5mm thick. The 6 speeds are 5.5mm thick but 0.5mm (0.20") isn't going to make that much difference. https://cimg0.ibsrv.net/gimg/bikefor...e88adcd53f.jpg verktyg :50: |
But they're reversible. Doesn't that make them all the same?

What # of speeds are you shooting for?
I have a 15T Uniglide cog and your choice of a 6 or 7 spd spacer. Cog measures .073” thick. Spacers measure .141” for 6 spd, and .123” for 7 spd. Not sure if this meets your requirements... https://cimg2.ibsrv.net/gimg/bikefor...f6bf8033a.jpeg |
I will check I may have one of these in my collection in ok shape.does it need to be a 15tr would 13t second ring be OK.?

WTB: DuraAce Uniglide 14T or 15T 2nd Postion Sprocket
Thanks for the responses....
When Shimano introduced the DuraAce 11T sprockets/cassettes they also made special freehubs with a smaller 31.9mm-33mm diameter threaded section (vs. the standard 33.5mm threaded freehubs). https://cimg4.ibsrv.net/gimg/bikefor...13887c1b5a.jpg https://cimg1.ibsrv.net/gimg/bikefor...bbfbb74656.jpg NOTE; There was a period of time when Hyperglide was being introduced that Shimano made freehubs with both external and internal threads for use with either style cassette.

The 2nd position DuraAce sprockets have a built in spacer and are: 6 speed - 5.5mm thick, 7 & 8 speed - 5.0mm thick. They are not reversible. https://cimg5.ibsrv.net/gimg/bikefor...bc3efef182.jpg I'm looking for a 14T or 15T Dura Ace 2nd Position sprocket that has spines towards the hub side like this one. They only fit over about ~2mm of the splines on the end of the freehub. https://cimg5.ibsrv.net/gimg/bikefor...b85bfa8570.jpg https://cimg3.ibsrv.net/gimg/bikefor...358a0f826f.jpg

There aren't enough long straight hills with tailwinds around here to run the 50T-12T combo, so I essentially have a 6 speed cassette. I have 13T and 14T screw on sprockets. A 13-14T or 13-15T small sprocket combo would give me more usable gearing. https://cimg9.ibsrv.net/gimg/bikefor...f55cf6e59f.jpg

I have Uniglide freewheels and cassettes on a number of bikes. They have a nice crisp feel when they shift. Not as nice a ramped Hyperglide but adequate. Changing the freehub over to Hyperglide is more work and $$$ than it's worth to me. Done it before... Same with filing down the splines on a Hyperglide cassette. Plus I want to keep it all Uniglide. Being a Luddite, I didn't have any cassette bikes until 2007 - freewheels and friction shifting only. In my first venture into indexing in 2007 I built a set of road wheels using Shimano Deore XT MTB hubs.with a 6 speed freehub. I changed the spacers on a 7 speed Hyperglide cassette and filed down the wide spines inside the sprocket. Finished it off with a 13T Uniglide screw on sprocket. It's worked great as a 7 speed! https://cimg0.ibsrv.net/gimg/bikefor...ca74599996.jpg verktyg :50: |
I will dig into my cogs and look I have a several DA 2nd cogs similar to what you want but there likely the 6 speed that had seperate spacer.

This is the easier way?* Yikes!
