ISM Saddle for road bike?

Follow Up Question:

How much Seat Tube Angle does the ISM Saddle make up for? Apparantly ISM advices to shift their saddle back by 5-8 cm. If I keep the Saddle position, this should result in a steeper Seat Tube Angle, correct?

  • 5cm gives me around 3.5° steeper Seat Tube Angle
  • 8cm gives me around 5.5° steeper Seat Tube Angle

This would help me to get a better position on my Cannondale SystemSix with clipOns
