well.. i have farsport wheelset.. but that purchased almost 2yrs ago.. so probably the ed hub won't fit 11 speed cassette?

but even then.. the red 10 speed RD is limited to max of 30t or does it support 32t?

@addictR1 correct, 10spd RD will work with 11spd cassette and shifter. Short cage is limited to max 28, have to go to Wifli, i.e. long cage, to use larger cassette. The limit of gears the RD will move to is determined by the amount of index points in the shifter, rather then any part in the RD.

edit - have heard some people have success with using short cage RD with 30-32 cassette by winding B screw and low limit screw to maximise outboard RD movement

pedantically the FD is changed, but people said it still 'works'

Pretty sure the normal red RD's are limited to 28t, but you can get them to work with more in many cases. You'd need a wifli derailleur to handle the 32 most likely. But you might be able to flip the b-screw around and/or stick a washer under the mounting bolt and get a normal one to work.

Wheelsets: 2 years old, depends which version you bought, and whether its a bit older or newer than 2 years - most hubs were 11s compatible at that point, but people were clearing out old stock in many cases. Pull your cassette off and see if there's a spacer there - Sram cassettes don't need a spacer on 10s, and Shimano 10s would have a single 1mm spacer. There'd be another .85mm spacer if you've got a 11s hub.

I've had good luck with 10s freehubs and a dremel though - it's only .85mm of difference, and many freehubs have shoulders that can be ground down pretty easily. I've done 3, and had no problems with them.

I have used a 30t cog on my 2012 Red 10sp RD without adjusting anything. I would not blindly adjust the limit screws- you should not need to change the limit screws to shift to a larger cog and if you get it wrong you'll shift the chain off the large cog and into the spokes.

The RD will handle the same large cog with 11sp as it did with 10sp.

Edhub is Bitex, and so is BHS. I think you can fit an 11sp BHS UL190 freehub if yours is not 11sp. See viewtopic.php?f=113&t=128572&p=1100334&view=show#p1100400

Sweet! Thanks for the info guys. FS said my Edhub would support 11sd. Might be worthwhile to give it a try.
