axle width in rear dropout issue
Hi, looking for some help here.
I have an awesome pepto bismol colored 90s Bianchi.
I am building it and it seems like the rear droupout doesn't want to accept the axle.
I have read that I could file down the dropout or the axle. I don't really want to file the dropout as it is chrome and that seems wrong. I will consider filing down the axle, but what is up with this? I've never ran into this problem and I am hesitant to start filing the axle (concerned about doing it evenly).. help!
