Hi folks, after a bit of help. I have a Trek Alpha 1.2 2010 with a 9 speed SRAM PG-950 11-26 9 speed cassette & Shimano Sora front & rear derailleur, which is currently mounted on my Wahoo KICKR. It works great & love the bike but would like to upgrade to an 11-speed.
What I’d like to know is if this is possible by just changing the cassette & chain, or whether I need a whole new group set?
