I'm looking for an affordable, sturdy, stiff and light tubular rear wheel for track. Something like DA hubs to Mavic rims?
I am also looking for a flite saddle ,with the cutout, used lightly?
My Pearl Izumi Road shoes have a stripped insert, and are a bit too roomy in the forefoot, so I'm looking for a pair of stiff and light road shoes to replace them with. Size 9. Like new or close to new condition?
And finally, I have been using my Omnium crankset with my CK ceramic BB on my cross bike, but I need to leave my Omniums on the track bike and get something similar for the cross bike. Hoping for used Omniums or the SS SRAM road crankset that's just a cheaper version?

Finally, finally, if anyone has a new/used Bell or Catlike or Lazer helmet that's just sitting around, my Sweep is overdue for retirement.

Thanks!

Please reply directly, off-list.
