34 tooth cassette with Ultegra 6800

[Twowheelxtc]

can anyone suggest where I can get a 34 tooth to help these old legs up the hills on an Ultegra compact 50/34? Shimano has an 11-32 for Ultegra but I'm sure will easily take something larger with some b screw fiddling.

Thanks in advance.

Nothing on Wiggle?

I went even further recently and put an 11-36 mountain bike cassette on my cyclocross bike. That has 10 speed STI shifters. 9 speed mountain bike rear mechs have the right pull ratio and range to cope with the huge cassette. I bought the parts from either Wiggle or CRC. If you have 10 speed Ultegra then you could do the same.

You will need the medium size cage rear dérailleur. Look for MTB cassettes.

Thanks Guys

I think I worded my question wrong! What I should have asked is whether there are any cassettes with sprockets larger than 32 that would be compatible with Ultegra 6800 11speed levers using the Ultegra gs medium rear mech. The problem is mainly one of correct cable pull from the levers I think as the rear mech will probably be ok with some adjustment.

Thanks for that.....do you know if the Shimano mtb cassettes in 11 sp have the same spacing as road cassettes?

They should be exactly the same spacing. I know that 10,9,8..... are
