I took it to my main man at Mamachari to check out. He trued the wheel for me but found something odd which he couldn't explain. Basically the brake surface was pushing out in odd places on different sides which he couldn't explain and his never seen anything like it. I had another rear wheel on order already so was just waiting and would swap it out. Told him I would have a closer look at the wheel to see if I could spot anything usual about it and report back. I mentioned that the last Velocity AeroHeat rim had a huge crack down the middle which you wouldn't see if the yellow rim tape was in place and then the light bulb idea came to us at the same time. Maybe the AeroHeat rim at split again and was wondering why.
Our theory is that under the extreme pressure of 100psi the Marathon + tires needed as well as my weight may have pushed it to its limit and over time it developed cracks which just got worse over time. Even though there is no mention of max tire pressure for these rims.
I took a very close too at the troubled rear wheel and our theory was right. The AeroHeat Rim had split again if you looked very closely. You can just about make out the crack developing. Not as bad as the first Velocity AeroHeat rim but I caught it much earlier than before.
