Copio correo de Mauro (dream bikes) con algo más de información sobre el sillin... Hi Ruben Sorry for the late reply, very busy days these! DB-M-FL central hole require walls reinforcements that makes the saddle less flexible and less comfortable. For a front suspeded frame I will choose standard DB-M which is available also with UD finishing. About saddle width...the rear end of the saddle isn't flat but 125 mm are measured flat but if you will measure it running around saddle shape you will have something like 135 mm. With a flat saddle both measures are similar.. Why choose a DB-M instead an MCFK? First, Because a DB-M has got a biomechanical study (almost the same of SMP saddles) and you've got a central depression and lateral slots for seat bones, this makes DB-M more comfortable for longer kilometrage. Second, because if you don't find it comfortable you can return it Mauro
