The Speeder 57 was a shaft made exclusively for Taylor Made and I do not have any specifications other then the weight which was in the 57 gram weight range. I would expect if to be a mid bend point shaft with mid range torque. There was a Project X Pxv that was designed for Callaway that was a mid bend point that weighted 60 grams for the S flex. If this is the shaft you are asking about it should play similar to the Speeder 57. Quality from one manufacture to the other on this type of shaft would be very similar, and both are very good graphite shaft manufactures.
We stocked the Project X Pxv Tour 52, which was designed for a higher ball flight and the Project X Pxv Tour 70 which was designed for a low ball flight. The numbers represent the approximate shaft weights.
