All the stock parts are holding up very nice.
Stem was broken when i bought the bike and cracked top top tube within a year.
The bike is pretty good. All the parts on it have held up very nice except for the frame and stem. I cracked the frame from doing 360s off of about 2-3 foot drops. The wheels have held up super well so far. No bends in the fork and i do grind a bit. Solid cranks, wheels, bars, forks. Ive been doing much bigger drops around 6 feet drops and bigger stair sets and everything is great. I did upgrade the frame though. The headset was replaced only after a year and a half which is good and the bottom bracket being replaced before 3 months. Overall a good bike for the price.
