I have a general understanding about topics above (scanned Sheldon Brown's site) but would appreciate some guidance for a future upgrade/replacement.
Currently on my Roadini I have DT friction shifters, GRX 2x crankset, GRX FD, 105 RD. 11sp There are a few things I'm looking to change: - shorter crank arms (probably 165mm) - silver over black (as much as possible) - maybe a narrower Q-factor of the crank, which may improve chainline (I may be mistaken) I believe the GRX crank is a little wider than a traditional road double, but it's a rather small difference and may be something I should ignore. Why I mention: for my bike fit, narrower is better, but what I'm more curious about is whether I can improve my chainline when in certain gears. I know that when I'm in the larger chainring, I can only be in the 4 smallest sprockets without rub. If I shift to the 5th or 6th sprocket, chain rubs inside of FD cage, if I trim it to move inside, it shifts down to smallest sprocket. Whereas when I'm in the small chainring, I can use 8-9 sprockets before any rub (and easy to trim to avoid noise/rub, without going into the big chainring. I realize this may not be about chainline, so please help me dial in my set-up so I can be in the large chainring and have more sprockets to use without rub (e.g., if a limit screw can move the FD inboard a couple mm, that may do it, but since the shop built this up I have not touched it, and it has always been like this). Regarding part swap, I can ditch the hollowtech BB and put in the square-taper that came with the bike, and then add some nice cranks in a silver colour, or keep the hollowtech BB and find a crank in silver, with 165mm arms, that works with the frame/set-up. I'm a bit lost here, but doing research. Thanks -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
