Hello all,

I am in the process of building a new road bike, and have run into what I hope is a fairly simple problem. There seems to be a bulge on the top side in my tires, both front and back. The rims are new vuelta aeromax, the tires are new Heng Shin, the inner tube is bontrager 700x18-23. It almost seems like the inner tube or tire doesn't fit properly. i have not even ridden the bike yet - still building it. Any help would be much appreciated.

Mike
