Sidmouth Posted April 27, 2015 Posted April 27, 2015 I am patiently waiting for either the Sram GS or Shimano XT 11 Speeds.One consideration, the hubs, I know Sram needs a new freebody hub which is screw on type, however what is the Shimano type and if you are running a standard 10 speed freebody do you need a new hub for shimano?
Captain Fastbastard Mayhem Posted April 27, 2015 Posted April 27, 2015 No, you don't need a new freehub body for the shimano cassette. It's the same one as your standard 8/9/10 speed body. What I'd do is pair the gx gruppo with the shimano cassette. far less outlay with almost the same range
Sidmouth Posted April 27, 2015 Author Posted April 27, 2015 how can a 11 speed cassette fit on a 10 speed hub, it does not work like this with road bikes, the 11 speed hub need is slightly longer is it not, that is why on a 11 speed road freebody you need a spacer to accommodate the 10 speed cassette?
Odinson Posted April 27, 2015 Posted April 27, 2015 Bud, if Shimano tells you their 11-speed is compatible with 8/9/10 freehub bodies, accept it as such. Go onto Shimano's website and do some research. It's all over the hub too (if you did a search you'd know).

GoLefty!! Posted April 27, 2015 Posted April 27, 2015 The Shimano XT 8000 cassette fits onto a 10speed freehub because the the size of the cassette places the derailleur far enough away from the spokes so that it does not represent an entanglemtn risk. The road cassettes with smaller large cogs bring the deraiileur too close o the spokes hence the cassette has to be spaced further to the right

Sidmouth Posted April 28, 2015 Author Posted April 28, 2015 on a shimano 10 speed MTB you also have a spacer , which is removed when you go 11 there is no spacer on my MTB freehub, there is one on my road wheels, the collective length of the 11 speed cassette is longer than the 10 speed, therefore i worry it will not fit

End van prent.
Skinnyone Posted April 28, 2015 Posted April 28, 2015 Shimano IMO learnt the hard way with the road cassettes, as there is little to no upgrade path with their own wheels, so they sat down and thought long and hard about the mistake on the road stuff and decided to make the 11sp MTB cassette fit onto the 10sp bodies. Like has been mentioned, don't question just do...
Sidmouth Posted April 28, 2015 Author Posted April 28, 2015 well that is good news and one more reason to go Shimano, with Sram you need a new freebody hub.http://www.chainreactioncycles.com/za/en/sram-xg-1150-11sp-cassette/rp-prod135801#

Sidmouth Posted April 28, 2015 Author Posted April 28, 2015 so could you use a Sram 11 speed cassette on a standard hub, but just remove the 10 tooth and put in an 11,
Captain Fastbastard Mayhem Posted April 28, 2015 Posted April 28, 2015 so could you use a Sram 11 speed cassette on a standard hub, but just remove the 10 tooth and put in an 11, Valid question, but No, you couldn't. The lower bits are machined out of one bit of material. And on the more budget GX one they're all pinned together. Plus you'd be taking apart a very expensive bit of kit for buggerall reason. Pls the Shimano one is compatible with the SRAM goodies. And it's not just the lower cog that's different - the whole cassette design is different and it won't fit a normal freehub body as it attaches very differently to how the "normal" cassettes attach. Essentially, you'd be bloody stupid. And you'd end up with a $ 120 - $ 400 paperweight. (depending on which one you buy)

Its not a mistake. there is a very valid reason for the need for the road cassette to be spaced further to the right and it has to do with driveside spoke clearance of the rear derailleur jockey pulley cage
