I know that people weld car bumpers. I wonder if you could do that.

Another option would be to find someone with a hot stapler.

Once you've repaired it, be careful what you put in it. I had one disappear off the back of the bike a few years ago with only a couple of kilo in it. The plastic had been weakened by dropping it. Repaired the small crack (around 30mm in length)  & all was fine for around 6-7 months.

I set off for a ride to the nearest beach with camera, kite and a few other bits in the box, but by the time I got to the beach, all I had left was a small piece of the base still attached to the rack.

Prices of topbox’s i’d Just buy another.

In fact I'm sure I can rummage around and find you a 55L or is that 50? Givi for 80 quid
