Finally I had the time to test my new saddle on tarmac and on very hard off-road.What can someone expect from a piece of hardware with the elasticity of a wood board and the plasticity of a granite stone? :) I wonderful ride!
Yes it's a very hard hide but already I can feel the saddle's surface getting rough in the sit bones zone. I guess it will take some 500km at least to break in, but I'll survive.
It's a big change from the city B66 and wider saddle. The narrow saddle will put more stress into my but. I guess I just have to get used do it!
