Hey everyone,
I joined the forum because I have a little problem, or a big one we'll see.
I'm trying to find a seat post with quite a bit of setback, Ideally I would like to get to about a 70 degree seat post angle.

I have limited range of motion in my right knee, it only bends to about 90 degrees so sitting farther behind the bottom bracket allows me to make a comfortable pedal rotation.
I currently ride an old Schwinn (1974 continental) with a layback bmx seat post that gives me what would be a 70 degree seat post angle, anything more than that and I end up having to slide back in the seat to pedal.

I want to upgrade to a newer lighter road bike, but given where I am coming from I'm not worried about the weight of the seat post.

Any suggestion is welcome, I just don't really know whats out there.

Thanks

I ran into the same problem. The only ones I could find were an arm, leg and and eye tooth. I wasn't willing to spend $200+ to get a seat post to maybe get a $400 bike where I could ride it. Yet I wanted to keep the bike, so I made one.

I took a $20 aluminum seat post from Performance Bike, and a neighbor had a pipe bender and bent it back as much as 4 inches. Course when you make one change, there usually is a need for another. This one was no exception.

When I put the seat on it I had a saddle no guy would ride. I had to grind down the metal inside the slot to allow the saddle to pivot to a rideable position.

With the pedal rotation sorted out, I tried to ride the bike then the handlebars were in the wrong position. I rotated them up and I have a bike I can ride now. Took some time and wasn't a project for someone that isn't handy. You also need to use common sense. What I did worked for me but if I had to go back much further Id weld some bracing on to be sure.

If you decide to do it, be careful and think everything through before you start. I wouldn't do this with the post that came with the bike. That way you can always go back. In my case I couldn't. The original seatpost was carbon fiber

does anyone know anything about the look ergopost 4, I've seen a wide range of offset specs, does anyone know how far it actually can go back?

yeah but the really offer almost no set back 16mm is the most i've seen on any of theirs, i'm looking for 40mm or greater.

that is about the most set back i've found with out going to a steel beach cruiser, braced lay back post (an absolute last resort). I've seen some people quote the look ergopost 4 as having 60mm which seems outrageous but I'd pay a pretty penny for that.

Looked into a Hase Trike once but they are so much more expensive, and I think I would feel a good deal safer on the roads on the standard upright, since I commute on city streets.
