I managed to snap the bolt in my axle on the cranks on my jump bike. I’ve tried drilling it but it won’t budge so need new axle. the problem I can’t find the size I need anywhere. The cranks are unbranded but came on a Last jump bike, I reckon at least 10 years ago.
they are 19mm axle, 140mm length but with ten splines. Any help is appreciated!
thanks

I could be wrong because I haven't done shit on BMX bikes and BMX cranks in awhile but I'm pretty sure those 10 spline spindles were kind of oddball, it might be hard to find one. Maybe somebody else can tell me I'm a big dumb stupid poopyhead and link you and easy solution. Probably going to take less time to buy an ezout and get the broken bolt out that way than to track down a new spindle unless the spindle is fucked.

Also whatever you end up with, check your crank bolts regularly, sounds like it broke because it wasn't holding the crank correctly and the crank was able to start moving into it and loading it.

Good luck
