    125 or 150 dropper post

    Looking at the ks Lev dropper post. How do you tell which work better for the ibis SL.

    Depends on how much seat post you have showing now.

    Measure from seat post clamp to seat rail and
    if >207mm, then 150mm or 125mm or 100mm;
    if >182mm, then 125mm or 100mm
    if <182mm, then 100mm

    Reference lengths are: drop length B (150mm,125mm,or 100mm) + post head I (22mm) + collar F (35mm)

    ***You may also need to add G (24mm) depending on which orientation you put the cable since it could interfere with the seat post clamp (others here may be able to confirm/deny this)

    Thanks. There's too many of these to know which one to use. Are these some of the better dropper posts?

    The externally routed KS Lev is one of the best, in my opinion. The rule with dropper posts is use the biggest drop you can fit, determined as described in the post above.

    KS posts are the best in my experience.

    As for 125 vs 150, I went from 125 to 150 and regret it. The 150 is too much of a drop.
    When I ordered my Ripley I made sure to get the 125. More is not always better in my experience.

    That said, see if you can demo different posts and lengths. Ride a friend's bike, do bike demos with adjustable posts...

    To each his own. I went to 150 a few years ago. Have since tried a few bikes with 125 or 100, and really don't like them as much. If there was a 175 option, I'd get that, as I have room on my bike.

    I concur with Kaj, I like to have the maximum amount of travel I can get out of a post. I am running a 150mm Lev and my new fave is the Yep Components with 155mm. When I go back to 125mm it feels like the saddle gets in the way. Bikes - Ripley and HDR

    I'm in dilema what to buy Lev or Lev Integra?
    From seat post clamp to seat rail I have 210mm so 150mm will be the best option?
    Any suggestions?
