You need to let us know what series it is.Guys
I have a dura ace setup with a 28 on the back and 36 front and the tough hills are too much of a killer.
What is the biggest cassette I can get on there. Is 32 doable?
I believe the rear mech is a long cage but not 100% sure. Is there an easy way of finding out?
Thanks
I seem to recall the old DA (7900?) the biggest cassette available was a 28t, which didn't change from the move to 11 speed with 9000, so there was no need for a 'long' RD. It was only the lower groupsets which had one for their 32t (and now 34t) cassettes. DA9100 now supports 30t and with some tweaking you can get it working with a 32t Ultegra cassette no problem (think Ollie from GCN did it when he Everested)...

talking about DA 9100 mechnical said:The rear derailleur has a radical new appearance prompted by the Shadow low-profile design first introduced on its mountain bike line, and it now accommodates a 30t sprocket, previously limited to 28t.
So what Ollie did, if you have old '4 arm' DA (9000) then I would say even with some careful tweaking the biggest you can get on there is a 30t. It's probably worth googling around as I'm sure someone else will have tried it with an in depth guide/video.
ELEMNT isn't massive. Mines pretty much the same size as my old Edge 810.Thanks guys. Will probably give the Wahoo Bolt an order, not sure if I want the massive Elemnt or not!
EDIT: Zipp argh!
LBS just emailed me back. Zipp rim for my 30 Course costs around £141 and has a 8-12 week delivery time. That's before they even consider the building (and I know they only like to build with new spokes) I had a feeling it might be that painful. I'm sure I've seen new/wiggle ebay complete wheels going for ~£150 with the SRAM XD freehub that nobody uses... So that's my current medium-term plan. But for now need to find a short-medium term rear wheel. I have my old AXIS 4.0 wheels... But that has a knackered rear hub. Might be a bodge to see if I can solve that...!
