I bought a Fantom 29er at the beginning of last summer. I went for 3 rides, and my derailer hanger broke. I ordered another one, fixed it, and it broke again after 3 more rides. Same thing again. I have never ever had a hanger break, and all of the sudden I broke 3 on one bike in 9 rides. Don't buy one of these unless you want to do a hanger repleacement or hike your bike back mid-ride every third ride.
