* The effective seat angle (D) indicates the actual sitting position on the bike, measured at a reference height (D2). Due to the offset of the seat tube in relation to the bottom bracket, the effective seat angle (D) does not correspond to the seat tube angle (D1). The effective seat angle (D) is therefore calculated from the intersection of the straight line, starting from the bottom bracket, with the height of the saddle rail (D2). The height of the saddle rail (D2) corresponds to typical reference sizes for the respective frame sizes.
**STR: The higher the number, the more upright is the seating position.
