I've had my enduro comp for about 5 months now, great bike and so fast and capable!
First change I made was a wide bar and 50mm stem, the xl came with a 90mm stem which imho has no place on a bike like this.
I quite like the formula brakes, had a few issues with the rear pumping up but a good bleed and new pads solved that, they feel good now, only question is longevity but I will see how long they last before replacing them.
I've had no such luck with the standard wheels and tyres, constantly putting holes in the tyres and finding the sidewalls too thin, found the rear tyre wanting to roll on the rim under hard cornering, even with high pressures and actually skinned a few sidewalls so stans leaked through them. Changed to a maxxis / michelin combo now which seems a lot better.
Standard wheels are ok but pretty flexy, had to keep tensioning the spokes on the rear until I destroyed it on a jump (my fault), have now replaced them with a hope / mavic en821 combo, loads better and the extra stiffness of a nice tight build seems to make the bike feel better.
You won't be disappointed with your choice, most capable bike I've ever ridden, just needs a little bit of tweaking I think to make it even better!
