    Extending shorter dropper post vs longer drop and slammed?

    Hey,

    I was curious about something regarding dropper posts in general. I'm 5'8" with a 31" inseam. I have a 2016 Santa Cruz 5010 (medium) which came with a 150mm Reverb. When it was time to switch posts I purchased a 150mm post in another brand (One Up).

    I haven't had any issues with it but recently had a pro bike fit done and was told I was losing power on climbs and top speed because I had my post too low. Now I've got the post up 30mm from being slammed and it's been working great and the fit is noticeably better actually.

    I'm curious if I should be looking to buy a 170mm or 180mm post now though that I can slam again to get the same overall height when fully extended.

    Is there really any difference between a 150mm post extended from the frame 30mm vs a 180mm post which would be slammed? (other than the seat being 30mm higher when slammed).

    Thanks!

    A longer post may not fit your frame. You may want to check that first.

    I would say it depends. My 175mm post is 30mm from slammed on my enduro bike. The only time I notice it is if I am trying to suck the bike up to get it higher in the air. I have an XC bike coming with a 150mm so that will be interesting. If I have to buy another one for the big it will be 200mm though.

    I suspect frame insertion will be an issue, too.

    I ride medium frames, too, and find that frame insertion is the bigger limiting factor than anything else with dropper fit. Both of my bikes could fit longer droppers if I could insert the posts deeper. I have to run less drop because of that reason.
