The Pescadero is an evolutionary hop and sidestep in the traditional road sport/endurance road frame. Most of the new "all-road" bikes embracing wider tires are automatically going to disc brakes. And disc brakes are effective technology that we also adopt on other Soma frames. But what about those who want the benefits of wider road tires, but want the clean, classic look of a road caliper brakes or just prefer their familiarity? Or how about those who have recurring nightmares of getting branded by a hot brake rotor. The Pescadero has these souls in mind. Its road sport geometry allows you to ride hard and long with less physical and mental fatigue. A great choice for gran fondos or all day rides on winding country roads. While you can throw on 700 x 28c tires like every other endurance road bike has these days, the Pescadero allows for plusher rubber up to 700 x 38c. - Tange Prestige heat-treated butted CrMo steel front triangle; butted CrMo rear end (NOTE: Size 48cm ONLY takes the dual pivot caliper).
