On a side note - my front wheel (RS11) really flexed when I put the hammer down this morning and the rim rubbed my brake pads quite badly. Is this because a) the wheels are flexy, b) I'm fat, c) my pads are too close to the rim or d) all three?
Obviously a combination of the three. 16-spokes and a 24mm deep rim is never going to be super stiff. On the other hand, you could try riding more smoothly, as I'm happy with the RS-80-C24 and I doubt that you're any fatter than me. If you need more stiffness, then either deeper rims (RS31) or more spokes (R501) or both (R501-30) will be an improvement.
