    Any help

    I bought a 2016 roubaix with di2. It came with the cg-r seatpost which has to much setback for my liking. Can I just reverse the post to make it work? It has a 100mm stem I and would have to get a 80mm stem to make it work for me if I leave the post in the original way which I don't want to do. Thanks for any help.

    No you can't reverse the post. And you don't adjust seat post setback for reach. Setback is for your balance point on the bike and handling. You change the stem length for reach.
    You can't fix stupid.

    Thanks for the reply. Specialized finally got back to me also and confirmed your statement. Yes it a reach issue (really lower back ) so I'll shorten the stem. I'm just a 60 y/o recreational rider riding for fitness so I don't care what it looks like. Comfort riding is my priority and really love the bike otherwise. I've always used 0 setback post's was the reason I thought setback was the issue.

    My Roubaix came with a 110mm stem. It was much too long. I use a 75mm 17 degree up angle stem to get the reach where I like it.


    I did switch my CG-R seat post for a Cannondale Save seat post in a 15 mm offset. The CG-R, at 25mm setback, put me too far back. My balance on the bike is much better being 10mm forward.

    With that little offset and such a short stem, may I suggest that you perhaps purchased a bike one size too big?

    The 56 was a little too small. I'm actually in between sizes, and also prefer the taller front end of the 58.

    As for the seat post, the bike feels more balanced with the 15mm offset vs the 25mm offset. Also, never change the seat post offset for reach. That's where the stem and handlebar changes come it.
