This has been a great bike for my son as well as myself. There are no issues with the carbon frame and it had a tune up last year and hasn't been ridden since. Upgrades and specs include the following:
- Fox 26 Factory fork with 160mm of travel with grip 2 damper
- Crank Brothers mallet pedals
- Cushcore in both wheels
- New tires - Specialized Butcher and Pergatory
- GX derailleur
- Dropper post - Xfusion Manic 150mm of drop
