Lightweight CNC close ratio 11s cassette?
Been looking, but the market is swamped with the crazy-wide stuff that's all the rage these days. I'm after 12-25 or even 13-25 (although that might not play so well with syncro shift, come to think of it - I think it's currently set to compensate the max number of cogs for a front shift and I might want it to go one more with the 13-25).
I had a super light two piece ti/al number on there with 10s mechanical, but obviously ally cogs wouldn't be a great idea with the Di2 I'm rocking now... I'd be happy with full steel or maybe steel/ti.
But I'm drawing a blank. I'd go Red, but AFAIK 11-25 is as close as those go, and the same for any other close ratio milled cassettes I can find.
Anyone got a lead for me?

RECON-One-piece Cr-Mo Cassette / Racing / Shimano 11s (recon-harry.com.tw)
I have no experience with this cassette but someone on Bike Forums mentioned it after I expressed concern about prematurely wearing out the 5 bigger titanium cogs on a Dura-Ace 12-28 cassette.
I currently use an Ultegra 12-25 cassette and I really appreciate its durability and smooth shifting. Other components represent better targets for weight savings.

Oh hey, I missed that Recon has a 12-25! Now to find someone who has it in stock.
Yeah, I'm totally across that, but that's my lowest-hanging fruit at 6.3kg. Interested to see the difference in shifting performance between this and my R8000 12-25.
I mean, look at this! Never mind the wanky plating, but the form! Sweet.

^^^ That does look pretty damn sweet, and I'd kind of like a 12-28t (also currently running a Shimano 12-25, but want a few more teeth on occasion)... but damn, that's expensive! I am going to keep it in the back of my mind when my current cassette starts getting near EOL.

Me too. The photos are not detailed enough to examine the shift ramps for a comparison to Ultegra. So if you do buy one let us know how it shifts.

Still cheaper than a Dura-Ace 12-28, and no worries about wearing out titanium cogs or carbon fiber spider on the big cogs.

I also managed to get in touch with Edco (finding their email was tough), but their 12-25 is discontinued. Maybe if they got a few more enquiries, they might make it available again... info@edco-wheels.co.uk

I have an Edco Campagnolo drive cassette that I like. They make a Shimano 11-23 that weighs 154 grams. They are good stuff. Swiss made, so not the cheapest thing. They list around 150 Euro.

I was so tempted (same $200 price as Recon) but then I looked at the specifications:
12-14-16-18-19-20-22-24-26-27-28
This gear spacing just makes no sense to me.

I wish I could remember the brand of my ti/al 10s number, but it's packed away somewhere - haven't put many k's on it, but the shifting was nice. Scored it marked down to AU$100!
Mind you, the splines were a loose fit; had to put a layer or two of aluminium tape on the inner faces.
Given that cog wear is mostly a result of chain wear, and such a cassette is pretty expensive, just change your chain often, I reckon. The grade of ti would certainly matter...

I also have a Campagnolo Super Record cassette which has 6 Ti sprockets out of 11. It is maybe 4 years old and it is just fine. Probably does half of my miles, so. around 6000 miles on it.
Also, my Edco's ratios are 2 cog skips between the bigger sprockets and one for the small ones. Same as the Campagnolo.

On the Edco.bike web site (https://edco.bike/collections/monobl...33253771116684) the 12-28 cassette is spec'ed at 12-13-14-15-16-17-19-21-23-25-28 / 188g, so the listing on that Prestacycle web site makes no sense.

RECON-Titanium / Racing
I'm curious about the durability because if ti lasts twice as long or longer miles than aluminum it would be worth the cost.

They have a titanium link at the top of the page.

To quote something I learned on Bike Forums: steel is real. (I think they were talking about frames though, not cassettes.)

It depends on the grade of ti. 6al4v is meant to be so hard you can only cut it with a laser or a water jet... Maybe someone can print a cassette out of the stuff.

Update: I got a pair of cassettes from Prestacycles about a week ago. One is an 11-27 and the other is an 11-32. Both are gorgeous little gems, and at 177g and 218g listed weight they are comparable to the weight of Super Record or Dura Ace.
I had planned to run the 11-27 on the Lynskey and the 11-32 on the Ritchey Breakaway, but fate intervened, so the 11-32 is on the Lynskey and the 11-27 is on the shelf. So far, that cassette has about 120 miles on it, and it shifts just fine. When I get my wheel situation sorted out I will put the 11-27 on the Lynskey and move the 11-32 over to the Ritchey.

6/4 Ti has a Brinell hardness number of ~380, so harder than 18-8 stainless (HB 200), but softer than hardened tool steel (HB 600-900). While acknowledging that there are a number of 6/4 Ti varieties out there, it’s no harder than decent steel. Ti brings light weight, corrosion resistance and fatigue resistance to the table. 6/4 Ti brings a minor increase in stiffness over other grades, but none are particularly hard-wearing compared to steel
