I think I have finally figured out a problem, it's the saddle. The problem is that I put too much weight on my arms, and it's bothering my one wrist, if the saddle were back another cm or so, it would be perfect, except the saddle seems to be as far back as it can go already. Okay, so I'll just tilt it back a couple of mm, except there doesn't seem to be a tilt setting. I'll take another look at it, in better light, and see, but it looks like the piece at the top of the seat post is a solid piece.
Anyone else have this problem, and figure a solution?
