I might have to give up...

I am seriously lopsided on the bike and there are some noises my B67 makes that just aren't going away. I'm guessing that I'm putting a big twist into the saddle frame with every pedal stroke. (even the sit-bone dents are uneven)

Wrote to Bill at Wallingford, and he sent me an email back right away. Sounds like I've done all the right things, but with my riding style I might just need a different kind of seat frame. One that won't give as much under my lopsided butt.

So I'm looking at B17S and B72. Anyone able to compare either of those to a B67?

My measurements put me just able to maybe fit on a B17S (outside edges of the dents I put on the B67 is 145mm, paper trick puts me at 170-180mm, turtle trick is 155mm). That one doesn't need a seat sandwich and doesn't have any springs. It's 177mm wide, but only 245mm long.

The B72 has the same dimensions as the B67, but has double rails and less-flexible springs. I dunno if I wanna mess with any springs at all. Dunno if I wanna mess with a seat sandwich, either.
