Just finished a year long carbon upgrade strategy. The comfort differential is appreciable. I’ve discovered with a carbon seat-post and seat you can run a higher tire pressure and not feel it in your butt bone.
I find speed at maximum tire pressure with less effort. Riding only pavement and concrete at these pressure levels. Carbon is worth the price. It’s light, strong, has flex, more comfort and looks great on any bike. Ritchey Carbon Components are beautiful functional perfection. Works of art they are.
I ride a mountain-bike built for speed on the hard surfaces. This Manitou shock is light for a shock. Adding overall riding comfort. It devourers rail-road tracks, rugged pavement and assorted pot-holes. Stability can not be underestimated and is worth the trade off in weight.
While considering speed consider Schwalbe’s G1 Speed tires. Very light. Very Fast. Tubeless even lighter.
A long strange trip it’s been. Just imagine what the future holds for cycling and humanity.
