Those are the first two frame failures I’ve seen on a Cube
I’ve worked in the local Cube dealers for a year & we’ve had them in stock for over two years & we have not had a single frame failure in that period, so the gaffer tells me.
Cube are good for honouring warranty stuff, we’ve had very little go wrong, bar a batch of RS Reba’s with a dodgy seal (very well known fault) which were sorted by Fisher under warranty.
Cube do put together well made bikes with great specs for a good price & the bike weights are very competitive.
They’ve been in the UK for around 4 years & they started in ’93 IIRC, they’re very popular in mainland Europe & not that rare so help is not too far away if something did go wrong
Most of the MTB range does come with a longer than you think necessary stem, must be a European thing!
The Fritzz’s we’ve sold still as far as I know have the OE stem & bars on them, the owners rate then highly as a whole bike & haven’t mentioned about any issues with the stem length or bar width, but it’s all personal preference as to what length/width you run
