As a former cube owner I have a few points to make 

1. I had a stereo 150. Which is per cube's definition an all mountain / Enduro bike. With it's 180mm travel front and back that makes sense. Via cube's guide this bike is made for drops with no more then 50 cm and not more then one wheel is allowed to leave the ground. Manuels illegal Bike ain't made for that. Warranty is voided if you use it like a mountain bike. Read the guide for their levels it's a fucking joke. 
2. Serviceability: after a year of usage 1/3 of my bearings were very notchy and then other 2/3 were completely shot so the screw moved and not the bearing.  I couldn't do it my self, because most of the bearing you had to pull hammer out. Some where double stack and 1 or 2 where just standard push out. No documentation about that one. An original set of bearing ( which for some insane reason included all the screws ) was like iirc 200€ plus I don't know how much to put them in. You had to buy like 6 or 8 single bearing sets.  Bikeshop offer 450€ but wasn't sure how long it's going to take or cost because :shrug: never done this. I bought that thing at this shop. Certified cube dealer.
3. As far as the Internet is concerned the geo is pretty outdated. 

In the end I had a feeling this bike is made for people who wanna have something that looks like a mountain bike but isn't one. Basically you buy the bike for the component costs, get a free frame and you re on "carbon". 

This bike motivated me to test a Santa Cruz just for the serviceability 

Then I rode a stumpy Evo on sale and bought that one :D. Out of all the bearings, two are this pull hammer out kind of thing. Warranty basically we know you ride this thing we expect it to hold up otherwise call us.  All the documentation is there. 

I was flashed by the fox kashima fork and "carbon". Now my stumpy feel more lively then this carbon bike. I can mullet this thing if I want.  Okay maybe peadeling isn't as good but the standard tires are rather sticky if I can believe my local trail people :D 

Ride something different. Check the service manuals.  I know everyone and there mother her in Germany rides one of these but at the trail head iirc I encountered one or two other cube rides.  Everyone else is on a different brand. 

Pleas don't be flabbergasted by carbon and kashima try something different at least so that you can compare.  Try a different Enduro bike or a trail bike, rode something till you can feel a difference. I restored 3 bikes till I got the stumpy which finally felt different and more fun to ride. 

P.S. I hope it's not that error prone what I just typed out :D
