Looking for a 12 speed cassette compatible with mechanical 105. It’s real flat around here, 11-34 seems too wide. I read somewhere the ultegra 11-30 was only meant for di2, not sure what would go wrong if I got one of those… Open to other suggestions.
Also a second question about a left crank power meter. I got new spd-sl cleats and all of a sudden my 4iiii power meter says I’m making 30 to 40 extra watts. When I recalibrated it gave the same value as before so not sure what happened there. Maybe the old cleats were so worn out that they were robbing me of all those watts? Seems crazy to me.
