Does anyone have any good recommendations on replacing the OEM brick of a seat on these bikes. This thing is extremely butt painful and I'm looking to replace ASAP! Thanks guys.

 

I couldn't rationalize the cost (I'm too cheap), but I really liked my friend's Sargent.

 

seat concept diy kit well worth the money and super easy to install yourself

 

+1 for the Seat Concepts

When ordering they account for your weight and shamefully, age, and can adjust the foam firmness accordingly.
Being old and 175 lbs, they recommended a half step softer on the foam. I could not be happier with the seat.
While you stand a lot on backcountry rides, you still get a lot of seat time. I have been happy with the seat having had it on both the WABDR (2016) and the IDBDR (2017).
