Bottom bracket issues

I've just got a mist chimera frame and when I tried to screw the bottom bracket cup in the non drive side it wouldn't screw in yet the thread seems fine it seems to grip for the first thread then pops back out

The drive side screws in perfect and it doesn't seem to be left hand thread either

Any help? Cheers jim

yeah Sounds like it's cross threaded can normally tell be able to tell just by looking at it or with a new frame paint gets over sprayed on to the threads.

Sometimes you can save it if you find where the thread is supposed to start and carefully screw in a steel cup, that's if it's not too buggered, or if it's over spray just brute force and a greased steel cup. A good shop might have the proper taps and could chase the thread and sort it out for you.

The good thing about BB threads is that they are nothing special, so Local Bike Shop would know what to do.

I took my seatless (so special+scary looking for a bike shop mechaniker) but he sorted out for free, as mine needed a small rechase

number 1 rule with BB: do not force it!
