    The Medium SB-66 has an 18" seat tube, the Reverb 125mm at full insertion is exposed by 7.25" the the bottom of the rails on your seat. That would put you at 25.25" for the total of the seat tube of the sb-66 and a reverb 125mm. Basically the length of your seat tube and post to the rails must measure 25.25" on your current bike for you to use the 125mm Reverb. Hope this helps.

    Thanks for the numbers Think i will be better of with the 100mm as my frame the now is 16.5" so i added 1.5" plus the 7.25" and it is slightly higher than what i run max when climbing.You can always rise the 100mm post a bit more but not the 125mm plus i only seem to run about 80mm between decending and climbing height thanks.

    I am 5'9" on a medium sb-66. I have a 380mm Reverb with 125mm drop. Works great and I use the full drop when jumping.

    I would say at least 125mm, unless you have really short legs I suppose. I have been riding a 150mm adj. post for past year (KS Supernatural) and still had to raise it some manually for the longer climbs about 1/2". Right now I am back to standard post and much happier for it, cause can put it right where I want it up and down (>6" differential ideal for me on 18" frame) and ride in mostly terrain that has longish climbs to mostly all down. I couldn't imagine why anyone would want a <125mm post, especially on a bike like this. But, I am a little jaded on adj seatposts since my KS failed again (6 times in past 7 months) that I am sticking with standard for now and lost almost a lb off the bike. My build is 31.8lbs now with some hard hitting parts (minus the shock) that feel like I can pretty much ride it anywhere! Sorry for the rant, go 125mm if you can.
    Ride On!

    Good inputs!.
    I currently run 3" GD on my 575 since that is the max I could fit in. I did'nt buy it but rather got it used from a friend and thought 3" was not good enough but it is great. I am sure 4 or 5 will be even better.
    So I am 5'10" and will get the 125 per your inputs.

    Yeah at 5'10" on the SB, think the 125mm would be best. I am 5'10" (no shoes), 5'11 tops with shoes, ride a medium and have to use a 150mm at least (think a 160 would be perfect for me), but then again I don't like adj. seatpost anymore or for this moment at least .

    Happy riding!
    Ride On!
