Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

... either that or it may need to be indexed.
I haven't tried to do this yet, but have watched a couple of YT videos and will give it a shot today.
For those of you who use the same bike outside and on the trainer, do you have to re-index the gears everytime? I have the same type of cassette on the bike and the trainer.
The trainer is a Tacx Neo 2T and required a 3mm spacer to fit the bike to make room for the brake caliper. Either way, it seems to me that even if the fit is a little bit different, it would need re-indexing every time, but I don't know.

Ok, so I twisted the barrel knob until the clicking noise is gone from every gear.
The only issue is that I can't shift into the largest cog on the cassette (easiest gear). I understand this is because of the L screw setting.
The bike is on my trainer and I'm worried about adjusting the L screw and forgetting about it and then putting my rear wheel on to ride outside and shifting into the wheel spokes (especially since I had the bike mechanic take off my dork disc last month
Is there any problem with just riding it with the L screw too tight (in so that it doesn't shift to the easiest gear)? Or is this going to stress the power train in a way that might damage it?

Did you touch the limit screw? If not, your barrel twisting probably just indexed the RD down one cog from where you should be and it's a lack of cable tension, not the limit screw, that's keeping you from getting to the last cog. Can you click past the smallest cog?

You should not need to make adjustments to shifters when moving bike onto the trainer or back to a wheel. You may need a shim on th trainer.
