Seatpost suffering a minor setback
I have for long been wanting a seatpost with a major setback; just half an
inch more than what I have, would be fine (for the steepest climbs.) And luckily today I found an inch long crack in my carbon seatpost. So now I must buy a new one - for safety reasons. ;-( Searching my favourite webstores I have found a FSA K-Force Carbon post which is claimed to have a 3.5 cm setback: But I'm no sure if that is enough. So now I need to know, how to measure setback on my present seatpost. One way would be to measure the distance from the center of the tube (post) to the center of the clutch (is that the correct English term for the device that clutches the rails of the saddle?) Another - and more relevant - measure would be the distance from the FRONT end of the ae... clutch to the center of the tube. Q1: Is there an acknowledged standard description for seatpost setbacks? Q2: Can anyone recommend a good seatpost with a big setback? Kindly Ivar of Denmark (pardon my English) -- Sendt med Operas banebrydende nyhedsgruppe- og e-postklient: http://www.opera.com/m2/ |

Kindly Ivar of Denmark (pardon my English) To get a variety of potential setback positions, the LOOK seatpost offers three, from which you would move the rails to perfect positioning. -- Les faits relatés ici ne sont que pure fiction, et ne sauraient être utilisés ou rapprochés d'une situation réelle existant ou ayant existée |

Kindly Ivar of Denmark (pardon my English) what was your original post? easton carbon posts have generous setback and have been very reliable for me. i'm no lightweight. |

Seatpost suffering a minor setback
Per Ivar Hesselager:
Q2: Can anyone recommend a good seatpost with a big setback? Titec's HellBent has a beeeeeeg setback, but you might not like the weight. Worked for me on an MTB for a couple years until I got a custom frame where I didn't need setback anymore - and I weigh about 220#. http://www.icyclesusa.com/catalog/se...c-seatpost.htm -- PeteCresswell |

It is not for the weight weenies, nor is it for those that need elegant styling. But dammit, it works on my bike! -- Phil, Squid-in-Training |

The FSA SL-220 is the aluminum version of the K-Force Carbon. It also has 35mm of setback. To measure setback, they measure from the center of the diameter of the post to the center of the clamping area. -- Phil, Squid-in-Training |

I'm surprised that you want more setback for climbs... I'd prefer just the opposite; less setback for climbs and more for descents. If you are currently sliding rearward on the seat (and the seat is level), then moving it forward should help. The reason why you are sliding rearward is because your weight is well behind the pedals, and your power stroke is pushing you that way. If you could get more on top of the pedals this effect would be less. |

If you could get more on top of the pedals this effect would be less. I agree. Look at the geometry. On a level road you want your weight balanced over your pedal stroke. On a climb you want your weight balanced over your pedal stroke, but now the bicycle is tilted relative to flat ground and you must move your weight forward with respect to the bicycle compared to level ground. If you climb a lot you want to cheat the saddle forward relative to its ideal flat ground position. -- Michael Press |
