I've been having a awesome time riding my new Catrike Expedition up and down the coast. I've been using a Schwalbe Marathon Supreme 42/559 on the rear and Kojak 35/406s on the front. All inflated to the minimum psi rating. This thing rides fast and comfortable. Who needs suspension on paved roads. I tried suspension and it wasn't worth it. More about that here.
I'll have more thoughts about the Catrike Expedition in later posts. For now suffice to say I think the Expedition is one of the best (maybe the best) trike on the market. Versatility, comfort, speed, weight and price.
