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

What do you mean 'disappeared'? Broke off? Does this happen often?

[Lee337]

The base broke away from where it was fixed to the base plate, so I lost the topbox & contents somewhere.

Does it happen often? Hard to say, it only happened once to me, but I've heard it happening to others when they put too much weight in their boxes.

I will admit to having a bike chain & lock in mine when I lost it, so it was probably overloaded anyway.
