I've been beating my head against the supply chain, vendor stockage, and data-dearth obstacles to finding 10 speed cassettes without spiders with a 20 t middle and 25 t outer, or 13-20 + 22 and 25 10 sp loose cogs, so at least for now the strategy is to stick with 9 (14-25 instead of 13-25) so that I can use 9, 8, 7, or even Uniglide cogs to build my cassettes -- (13)-14-15-16-17-18-19-20-22-25. 

Friendly listers have suggested eBay, Spanish, US, and British sources, but neither cassettes nor all cogs are available.

I can find dozens of 14 thru19 cogs; 20s and 22s and 25s are less common.

Point: If you have 20s or 22s or 25s to sell, please advice. (Need not be new, but must be little worn.)

I will also buy any 13 t outermost or 14 t outermost that you have for sale.

Thanks

I remember seeing these from Bikeinn .... This is not a good time to buy from Europe right now as shipping prices have been inflated due to less airplane travel. Usually they are not this high.

FWIW ....




Mid position 13's also

Thanks, Garth; I checked their site this morning, but shipping is prohibitive. I'll keep an eye out on Bikeinn and the British vendor I mentioned, hoping that supplies and shipping will get more or less back to normal before too long.

Oh yes .... I had some fun with the shopping cart shipping estimator. It didn't take many cogs, just cogs alone, to get the price of USPS shipping over $80 !

Really ?  Haha !

I did a little bit of internet research since Patrick Moore sometimes struggles with this.  I also put my hands on some of my own stock.  I have the following items to report:

I own a brand new SRAM PG950 cassette in 11-34.  It disassembles into individual cogs and the 11-34 includes a 20.  I disassembled mine to confirm it.  You can sometimes find a PG950 for as little as $20.  Here is a link to the SRAM page that lists all the cogs.  My guess is Patrick Moore would use at most 3 of the 9 cogs, so it might be too expensive for him:


I own several Deore XT 10 speed 11-32 cassettes.  There are two carriers, with three cogs each.  The smaller of the two carriers has a 18-20-22, permanently and inextricably attached to a carrier.  Even though Patrick Moore needs a 20 and a 22, I suspect he cannot stomach the jump from 18 to 20.  The four remaining loose cogs would be 11, 12, 14 and 16, so Patrick Moore could possibly get 5 usable cogs out of a $50 cassette.  

I researched the cheap Shimano HG-500 10 speed cassette.  I am 95% sure it can be completely disassembled into individual cogs, and it costs $37 at Jenson USA.  The full cog progression is:11-12-14-16-18-20-22-25-28-32

I recommend you put your hands on a 10-speed HG500 and confirm you can either unscrew a pin or grind off a rivet to get the cogs apart.  If you can, then you could get a bunch of matched 10-speed spacers plus as many as 6 great cogs all for $37.  Once you confirm that you can take it apart, you should buy 4 of them.

Thanks, the HG500 looks like a good option at about $6 per 10 sp cog. I'm near to buying -- something. Report at 10.

At Nashbar you can buy the 11-32 for a dollar cheaper ($35.99)  -  LINK
And you can buy the 12-28 for $29.99 - LINK

Between those two cogsets you have every Shimano 10 speed cog covered from 11 to 23 teeth.  

Buy three of each and this would be your 10 speed shimano cog board:

3 x 11T first position 
3 x 12T first position
3 x 12T second position
3 x 13T second position
6 x 14T 
3 x 15T
3 x 16T
3 x 17T
3 x 18T
3 x 19T
3 x 20T
3 x 21T
3 x 22T
3 x 23T
6 x 25T
6 x 28T
3 x 32T

That would be a total of 60 cogs, for under $200.  If you were to sell a few 28T and all the 32s to your friends for $5 apiece, and use the 11T's as christmas ornaments, you could be down to under $150 invested.  Assuming you have the 13/14 situation covered, then you could have your ideal 13-25 10sp, plus an essentially effortless exchange of a 20 for a 28 as a hillclimber event setup.  You could even run a 14-23 10 speed straight block if you so choose, or a 13-22, or a 12-21.

I thought my idea was such a good one that I did in fact order three of each from Nashbar.  That's a calculated risk because I am not 100% certain that the HG500 is disassemble-able.  

Assuming it works out as planned the next step is to start designing my cog board....

Raise your hand if you remember cog boards.  It's not always been cassettes.

I remember Doug ! The wondrous days of walking into the shop and seeing the magical SunTour board filled with cogs, bodies spacers and micro spacers... and the charts. I still have a couple of those customs as well as some other stock ST freewheels I've kept since the 80's. I do love that distinct sound of them freewheeling.

I so wish some company would make bike parts that were timeless, so to speak. Imagine still being able to get all those great parts from the 70's,80's and 90's today. Enduring Durables !


I found fotos of the HG500 cassette back sides btw, they have flush rivets that will require some drillin'. Too bad Sunrace doesn't make cassettes that use even numbered cogs as their non-spider cassettes use a single easy to remove torx bolt to hold them together.

That won't be a problem; Patrick's pretty handy with a Dremel.  :)
