FARK me, I knew it would be a lot, but.........
I'd be tempted if
a) it was made by shimano and therefore made from cheese, but at least it would Edam rather than primula so the mechs might survive one lap of stainburn.
b) the cassette was 11-42 (and therefore fit on a normal hub),
c) the chainring was a normal BCD, but then I bash my ring a lot so I'll ptobably stick with a full chain device.
I wonder if Shimano will respond? They didn't really to XX, they just made XTR (and everything else) 10speed (but then so did SRAM with X.0/9/7). But this seems sufficiently different, and they've got a new road freehub standard with the lastest 11 speed DA.
On the other hand assuming SRAM have patented the overhanging cassette idea, then I can't see it taking off, we've not had a new freehub since 7 speed, and even then they were backwards compatible for a while with threads inside and out. Would people throw away their old hubs for a new standard?
