This morning I had a rather big off and as a result my Scott Scale frame is looking worse for wear. The stem which does not clear the top tube hit so hard it passed over the top tube.

It’s taken a gouge out the top of the frame and must have compressed the top tube with the force. It’s gone back to normal shape and does not look that bad.

My concern is a 900g frame probably was not designed to deal with that kind of impact?

What do people think? Am I rightly worried?

Pictures?

The worst that can happen is that it snaps and you fall off.
Same could happen if you hit a rock you didn’t see – it’s just mountain biking.

Ride it and if it breaks, it breaks.

How did your brakes/shifter get past the top tube if your stem won’t?
I’d say there’s a good chance you’ve cracked some structural fibres if you’ve forced the tube to deform that much to have the stem pass across it.
If it were mine… I’d be getting it repaired/replaced tbh.

I’d assume the bars have a big rise. If so, get a stem with some rise and bars with less and you may avoid the problem in future ?

The gear shifter and brake lever both moved with the impact. The stem then managed to shift after the other parts moved. Bars are a 10mm rise jobbie.

I will get pics up shortly.

Very knowledgeable, and surprising what they can fix.
