So, time for the first tire change on the bike. Took my wheels off with no issue besides needing to go find a 14mm Allen bit for the front axle. Went to put the front axle back in so it’s secure while I’m getting the tires changed out, and the threads won’t bite. Threads aren’t damaged on the axle and I ran my finger inside the end of the fork and couldn’t feel any damage on those threads either. Any thoughts on why it won’t thread in?
