Good morning!
I have a Fezzari (now Ari) Empire with Shimano 105 Di2. I got the Magene PES P505 Base last year and put it on but then ran into an issue with the crankarm rubbing against the Front Derailleur. It turns out that the q-factor for the Magene is 1mm narrower than the default Shimano crank. I did get the rubbing to stop last year after a lot of fooling around with the derailleur setup. This year, when I took the bike off of my indoor trainer I checked the cranks and made sure everything was tight. It seems that the left crank arm was a little bit loose and when I corrected that, the rubbing came back.
Any suggestions? I’m thinking about trying a 1mm spacer between the bottom bracket and the drive side, but didn’t know if there were any other options that might be better.
