Hi all, I was just wondering how important is it to sit as much above the bottom bracket as possible as advised by all the various experts? I have a Kona which has a long top tube meaning that the seat is some way back from the bottom bracket. This is now exasperated by the fitting of a thudbuster, which has a rearward action as it compresses the parallelogram. To get a fit I’m used to I have pushed the seat as far forward as possible. If anything the frame is slightly smaller than my other bikes. Any advice would be gratefully received.

It's one of these things that will vary with the overall geometry of the bike, yourself, and how you ride. It /is/ worth experimenting with the saddle position, moving it forwards and back as well as up and down, and experiment a little with tilt too. When I've done this it's readily apparent to me what works best.

Try it against the old setup and see which feels best in practice. Worth rather more than theory IMHO.

Not all of them.

It's as much to do with the down tube (or distance from BB to back end of top tube if you don't have a normal down tube) and the angles.

Maybe you're fine as you are (probably so if comfortable), or else the bike (and maybe all your bikes) are too large for you.

Which experts are they? AFAIK having the saddle farther back can be more comfortable for climbing in the saddle OTOH track riders generally have the saddle much farther forward. I think you can place it where we feel it's most comfortable.
