My della santa steel frame has mavic helium clincher wheels mounted front and rear. When I make a hard right turn with the chain in the smaller cogs 12, 13, or 14 while in the 53t ring, the begins to slap the chain stay as if the freehub can't keep up. My chain is at a good length-just makes the big/big and no XS slack in the small/small. I took the freehub body off and lubed it, but this has made no difference. The hub bearings are fine and adjusted, and this only occurs in hard right turns. What gives? Axle flex causing the freehub to drag a bit? Thanks for any ideas.
