Using ultegra R8000 with 105 system?
Hi,
I have recently bought a Wahoo Kicker Core for indoor cycling, it already had installed a shimano ultegra R8000 11-speed cassette but the bicycle im using - a Trek Madone 3.1 has shimano 105 gearing system, with a CS-4600 10-speed cassette installed on the backwheel. I already tried to adjust the gear system to the ultegra cassette but didnt find the result optimal. My question is wether i should buy a new cassette for the Wahoo and if so - which one would you reccommend? Can i expect a better result with a 10-speed 105-cassette than with the 11-speed ultegra?
Thanks in advance for all responders!

Obviously (or not) you can't use an 11 speed cassette with a bike that has a 10 speed drivetrain and expect it to work properly. You need to get a 10 speed cassette and use the 1.8mm spacer that probably came w/ your Kicker...if not you need to get one of those spacers as well.

Yep, as noted...replace the 11 speed with a 10 speed and you should be golden.
