Ordered one up yesterday for my 6'2" 230lbs. to sit on...
Coming off a Selle Royal Resprio Moderate that has worked very well and eliminated past numbness, although the rails are starting to loosen somewhat after 1000+ miles on a Cane Creek Thudbuster L-T. I recently built a new bike and put the Resprio on it, so I had to use the stock WTB MTB seat that came on my Hightower again. Oh what a PITA it caused on my last ride. Probably a great seat for aggressive riding for a non-clyde without numbness issues.
Now that I have two bikes, I decided to give the Selle SMP TRK a try. Can't wait to try it out.
