|Kinda scary about 10k into my ride yesterday heard a pop in the front wheel, thought it was a broken spoke. Stopped to look and the whole side of the hub flange was cracking, first time I have ever had this happen in more than 18 years of wheel building, its a Sun Ringle Huba buba hub 36 hole thought it would be industructable I have about 2500 miles on hub always checked for trueness and tensioned with a tensionmeter. Just glad it was a high count training wheel not a 16 or 24 count race wheel. Made it back riding to the car to swap wheels but rode ever so slowly. Oh well I guess first time for everything.

|Looks like it was rebuilt without placing the spokes in the same direction as before. In some of the spoke holes it appears to have wear from prior spokes not laced the same. I've heard conflicting reports as to this being a problem, but after looking at this I'm beginning to wonder.

|Never had it happen to me personally, but a friend of mine who's in a wheelchair had one that pulled out about 5 spokes (radially laced). I rebuilt the wheel using another hub he had from a trashed rugby wheel (radial laced again). It's more common on radial lacing, but can happen to any wheel.|

|Theres no guarantee Sun will do anything about it but it broke under normal use and wasn't crashed so its worth a try.
Good luck getting everything fixed and good to hear it wasn't a catastrophic failure.

|This is a very common failure in CNC hub shells. The problem with CNC components is linear gain, which propagates cracks. Forged hubs don't have this problem. See the following link for a better explanation:
