Edco’s Wheel Saving TEN+ELEVEN Monoblock Cassette Now Available through Reynolds Cycling

Afraid you’re incorrect James S; 11-Speed cassettes usually only work on 11spd freehub bodies or those that were, seemingly, pre-made for 11-spd compatability (like Mavic freehubs). There is no 10T cog for Sram road; only MTB.

I second Sam’s concern about the overhang rubbing frames. I also assume that use of this cassette would involve re-tuning the rear derailleur every time you want to use ‘normal’ 11-spd wheels?

Only the new 11 speed xtr works on old 10 speed body’s. Learned this the hard way. Had to buy new wheel set when I was already locked into cx1.

@ James S

Nop. Only on Mavic’s 10s shimano/sram wheel will take a 11s cassette : http://velonews.competitor.com/2014/07/bikes-and-tech/technical-faq/technical-faq-1011-speed-compatibility_337803

I also think ratios are tight enough on a 10 speed road set-up. But when my current groupset/wheelset will ware out in 2-3 years, 11 will be the only option anyway.

The only bummer is my racing wheels, on which I roll less then 1000k a year will still be 10’s. This is why this cassette is interesting for me (they are not Mavics.)

Sam, I would guess that using a narrower 11spd chain, the smallest cog could stick out a little more. Also, being a monoblock design, the rear of the largest cog could easily be dished to sit closer to the spokes at its outside diameter (where the teeth are). So, depending on the extra spacing needed, either/or both the above could be used?

Shafts, look at the structure, it doesn’t need a tube spacer to support it.

That said..most wheels can be adapted with a file. A SRAM RED22 cassette probably won’t work for this because the back is flat but a cheaper SRAM cassette and any Shimano cassette will work. Its a one time fix and way cheaper than buying these over and over again.

I’ve done this with 2 Shimano hubs, a DT hub, Zipp Hub a cheapo knockoff for a friend and soon a HOPE hub. This is still a great solution if you don’t mind spending money and are afraid of screwing up your freehub bodies

^ You sure about all that, Veganpotter?

That’s some pretty fuzzy Materials Science and warranty voiding right there

Also…it’s not like engineers don’t make products that don’t fail all the time anyway. They’re constantly playing with what they think they can get away with when it comes to lightweight, high performance equipment. Hence…the 3 1st Gen 10speed SRAM RED cassettes that fell apart on me when the glue holding the backplate came off.

Veganpotter, I’m not sure what you’re on about regarding materials. You say you wish the cassette were “chrome steel” because it would be heavier but more durable. I assume you mean 4130 or a similar alloy (commonly called “chrome-moly”). The thing is, this *is* made from chrome-moly. At least that’s what it says in the article.

Furthermore, all steels are pretty much the same density (~7.85g/cc) and have pretty much the same stiffness. (Hardness is wildly different, though).

Then you point out that stainless and Ti wear out faster than chrome-moly. That’s true–there’s that hardness–but again, this *is* chrome-moly–and a heat-treated (hardened) variety at that!

So what on earth are you trying to say about the material here?

James S: With regard to fitting an 11spd cassette, the freehub body is usually 1mm different. This also means that if you fit a new freehub body (many older wheels now have 11spd freehub body aftermarket options) you may need to re dish the wheel too…what is that about one step forward and two steps back….?

@Bob- not true. The DT 11spd Conversion requires re-dishing, and does not replace the axle.
