I'd have probably kept the X2 in the Levo, but the shock is now faulty. Air has air mixed with oil. I first noticed a sloshing sound when compressing the rear. After a few more rides I could feel a slight knocking feel in the rear with small repeated kits (for example riding over 200 metres of tree roots, it felt a bit off, slight bumping sensation).
I know something wasnt quite right. So I took it out. Letting out a bit of pressure out and compressing the shock and watching it return, I could see it 'bump' through the travel... ie not completely smooth - it would start smooth and then almost stop, then bump through the final part of the travel.
I've really liked every coil based bike / shock that I've ridden, so hoping that the EXT lives up to to its reputation on the Levo.
