max seat post aft adjustment not enough

My seat aft adjustment is at max and I feel like I could use about 0.5-1cm more. Before going out and getting a new offset seat post I was wondering if there was any other adjustment I could make to try and get my seat to feel further back? Its not a reach issue but more to do with my body position while pedaling. Any ideas?

Only thing I can think of is a different seat with longer rails. Roger

Are you going by marks on the seat rails, or by sliding the seat back till the rails bend?

Setback seatpost is the answer.

If you are having pain from your current riding position and need to go back further, that's fine. But if you are not having pain, then trying to put yourself in compliance with KOP's or any other standard fit seems misguided.

I don't know you and I've never seen your bicycle so take this for what it's worth.

My general philosophy is that if your bike can't be adjusted to fit you without having to resort to something goofy, something's seriously wrong. What makes you think that your bike is the right size?

Whether the OP need something "goofy" or not depends on the seatpost he has now. If it a common 15 to 20 mm setback post then, yes, his fit requirements are unusual. If it's a zero setback post then buying a normal setback post is all he needs.

What makes you think the current seat post isn't goofy?


And what size bikes have radically different set back? Some brands use the same seat tube angle for all size frames.

It's always good to hear that I have been seriously wrong for decades. The position the results in long term comfort for me has me riding seatposts with a ton of setback on three bikes, seats slammed on the other two and stems of 175 and 140mm on my two stock bikes and 140, 130 and 120 on my customs.

All the bikes that have fine rides for me have very steep seatposts so I can get the rear wheel far enough forward for confident weight balance on mountain descents and turns. To get my seat where it needs to be with those steep seattubes, I need the big offset. Now, on my fix gears, I rotate my entire position forward so bvars go forward and down, seat forward and up so stems get longer and setback needs decrease. Currently only my Peter Mooney has stock both stem and seatpost. (Stem is a Pearle 13, 140mm. Seat is slammed. Fix gear with deep, long reach pista bars.) My good bike has the "normal" 120 stem but a custom setpost of about 40mm setback. Frame is custom, designed to keep the stem to 120 with the position of my other bikes.

So, to Retro Grouch, human bodies vary a lot. For many of us, finding that stock bike that really fits with stock parts can be a very tough challenge. (My racing bike did. It was an extreme criterium geometry frame. Perfect fit when I was young enough and strong enough to ride low enough to be aero with my arms bent 90 degrees for hours at a time. It had no use as a post racing bike for me. I have never seen since seen a non-custom frame with that fitthat would serve as a good bike for my post-racing days riding.)

OP, seriously consider a seatpost of more setback. (If you can find it, you might want ot try the SR MKE post, made years ago when the mountain bikers were playing with post you could push you seat back a mile on for radical downhills. I have one on a bike, shimmed a lot to bring it up to the 27.2mm seattube. With that post, you can play with setback realy easily.)
