Have a look at the geometry of the 2015 Cube-the top tube is now longer than they were & the issue with the mech hanger now sorted on the revised version.
Cube are fantastic value kit-wise but their frames leave a lot to be desired, and that’s where you want to spend the money.
Based on what exactly? They’re extremely well made, good quality kit & incredibly reliable.
I’ll admit I used to think the same about them, until I started working on & riding them!
