Upgrading Sram Red to 11sp

[BeeBee30]

What is interesting is there seems to me to be potential to make free hubs that are not Dura Ace 11 compatible work?

Eye-catching topic title fully borne out by the content within. What even made you think the conversion to 11sp was possible, had you already been inside a Red shifter and decided that the mechanism was suitable and there was enough material on the ratchet?

I wonder if Shimano producing a mechanical 11sp will prompt Sram into doing the same thing.

Sure, if the hub has a DS flange that's far enough in and the hub leaves enough room. Monchito started with a Mavic hub which already has an extra spacer to run Shimano cassettes. Hubs that can fit Campy freehubs without redishing would be the best bet.

I expect to see Sram 11sp in a year or so. It'd be great if it was just a new ratchet.


Monchito, any chance of producing the ratchets, possibly on an exchange basis? Are they different between the models of shifters?

Super-impressive work. I am also curious why you even thought this would be possible.

For the cassette, could you simply add an 11 cog to a Recon 12-25?

I also like the 18, but for that I have a 12-23, and skip the 11.

Hats off to you Monchito. Now, if you, Berk, Weeracerweenie and Wally went into business I'm sure you could come up with an new entire WW branded groupset.

and how it is you have the access and skill to the machinery necessary for such an undertaking!

It's fairly basic machining stuff. Have a quick read over some car forums and you'll see ridiculous backyard operators. As far as bikes go though, this is next level stuff.

It may be traditional machines, but looking at those tools' size, I'd hardly call them basic.
What impressed me was how well the steps were thought out: making a tool to hold the part, I'm assuming you took measurements for where the groove would need to be to move the derailleur the correct amount, etc. Or maybe you tried a dozen times and only showed us the successful pics? Somehow I doubt it.

I think we should start a collection so this twisted genius can get his Dura Ace 9000 cassette and works his magic
