BEST FOR: Long painless miles.
THE TEST: This fourth generation of Specialized’s endurance bike still has the road-muting cushiness of past iterations, thanks to a new, larger elastomer-insert design in the seatstays and fork. But where past Roubaix could feel a bit soggy, the SL4 is lively, courtesy of the rigid Coke-can-size down tube and bottom bracket mated to snappy, pencil-thick rear stays. The long wheelbase and taller headtube were notably stable on rough roads and techy descents. “Reminds me of a Caddy with a V-8,” said one rider. Shimano Ultegra components are great value for the money.
THE VERDICT: Don’t call it a comfort bike—it’s a fast roadie that’s comfortable. 17.3 lbs
