General Information
The LJ 1000 is the model on the lower end of the SLJ Series and very similar to the LJ 4000 except the metal parts which were significantly heavier with the LJ 1000. The model assignment "CP" stands for "Course Professionelle" dedicated for racing. The jockey wheel cage is mounted to the lower knuckle bolt in the middle between the wheels. This reduces the capacity (and better adapts to lower sloping racing freewheels) as compared to the "T" (Touring) Models where the wheel cage is mounted higher to the upper jockey wheel (see LJ 1000 T for comparison). The model presented here, does not have the plastic chain guide on the upper (lead) wheel.
