When switching out the stock seat for a Sargent, bare in mind the Sargent is a thicker seat and will likely set you up taller in the saddle. This might mean a slightly different geometry and more body weight against the grips, just what you don't want, more pressure on your wrists. Just a thought to consider, not much hoopla about it, but it was something that I encountered. I midigated this by raising the handlebars with the FBF risers. Easy to install, not cheap though. Or, the seat change may not make a negative difference at all.
I've had two Sargent seats, excellent product.
