Best 10 speed group? Or try to convert wheelset?

[loudtiger]

OK, took the freehub apart and here's what it looks like.

I did some digging and it almost looks like some bitex 6 pawl design. There are some freehubs in eBay but I'm unwilling to spend the $35 for what is essentially a guess. Anyone know for certain what this is?

Thanks for all the responses, definitely have some ideas in my head about what to do...

Edco Monoblock or machined Ultegra 6800 cassette and you're set.

In my opinion that $30 gamble with the bitex hub is a damn good one.

All the pictures I looked at online are the same as the bitex 6 pawl design.

I'd suggested measuring the dimensions of the hubs, and checking it against the Bitex ones. That way you'll at least know if it definitely won't work.

Many moons ago, I remember that the DT240S 11sp freehub change messed up the centering of the wheel, requiring a re-dish of the wheel. Could the same also happen with the Bitex freehub?

You can also consider the Wheels Accelerator 11 cassette. That's a conversion cassette fits a 10 speed freehub body with Campy 11 speed spacing. Will work for SRAM and Shimano 11 as well.

I had bought a set of carbon tubulars recently and pulled the freehub yesterday and lo and behold same one you have.
I believe mine is a set of Bitex Rar12 and will be ordering the 11 speed freehub.
I was able to install an 11 speed ultegra cassette on the current FH but the 11 tooth cog would spin.

The spinning 11t cog could also interfere with your seat stay and/or chain stay.

Bridman, copy not planning on using it like that was just trying my luck.

[Birdman]

lol gotcha. I actually DID try to ride it like that... and failed...


Reiterating the conversioin cassette option. I have success with this.

Token makes a cassette for 10sp hub body with 11sp spacing and cogs. ^ This is actually my C24 7850 wheel with the Token.

Alternative already posted is to run 11sp group as 10sp using the 11sp spacing by dropping the 11t cog, use a 12th lock ring and finally limit out a shift on the inside or outside. Works great. Did this for over a year.

Token 11 Speed Cromo Cassette 11-28T 2015

$250 USD, does that sound right? Although totally worth it for a nice wheelset though, if freehub upgrade isn't available.

@mimmason-did this work without any modification of the hub flange on the c24's?

[duvivr6]

Done with my 11 speed upgrade.

By looing at your hub I think you need a diferetn freehub. The bearing onn yours looks much smaller.
There are 2 bitex type freehubs available I have the RAR12 bt I believe the RAR9 has the smaller bearings.

@duvivr6
awesome, did you have to redish? you went from shimano 9/10 to shimano 9/10/11? i might go with that too, since campy 11 and shimano 11 speed cassettes seem to have the same distance between cogs. Hopefully no redish required. I sent a message to an ebay seller selling bitex rar9 hubs to make sure it is the right one.

Glad to hear it worked for you. This would be the most economical choice - only $35 instead of upwards of $100-$200 for one of those fancy cassettes.
