I was pleasantly surprised condidering the price. The frame is straight, the welds are excellent and the dropouts and thick!

Frame looks good, but the dropouts on the forks look like they were cut uneven on the front side. Decals were all bent up.

Everything came as described the euro bottom bracket was a little warped so we had to shim the bb bearings with a soda can to create a tight fit
