Front derailleur rubbing on crankarm
Hello,
I would like to adjust my FD because the chain is rubbing on big chainring-smaller cogs combination. To do so I need to move my outward but I simply can't because if I do it touches the right crankarm...! Crankarm is from the magene spider powermeter, it's not stock shimano (I bought it as a frameset so it never had a stock shimano on it)
Any idea how to fix this ?
There is currently 1 mm gap but chain is rubbing on the last few cogs when i ride outide and almost mid cassette on my hometrainer
