Hello,

I've just got a Cannondale Synapse Carbon Disc Ultegra (catchy name) and have been on one ride.

I've just noticed a small hole above the bottom bracket in the frame, is this supposed to be there?

If so what is it for?

    Not sure if the image worked so here's a link http://imgur.com/IP2gmpd

    Yes, I've seen that before. It's for the front derailleur wire for electronic shifting I think.
    I'm left handed, if that matters.

    Hmmm. I have di2 and that seems to be connected behind the seat tube.

    Maybe this is for mechanical cables?

    I'm just a bit worried because I didn't notice it until after 1 ride.

    I nearly said that! Took a guess at which side it was - it's for mechanical then. They have both but one is obviously redundant.

    If that was my bike I'd fit a blanking grommet or tape over it.

    Yeah I was thinking of looking for something.

    There's two unused holes at the front too...I was just confused by this one as it isn't quite as neat as the others and I hadn't noticed it, I was worried something had happened.

    My first carbon frame and first elecronic groupset...its awesome but I'm a bit nervous about something going wrong with it at the moment.

    If you bought it form an LBS you could ask them if they have something suitable, I'd be worried about water ingress into that part of the frame/BB area.

    Cool, I'll give them a shout.

    Looks like online there are specific Cannondale plugs for these holes so fingers-crossed they have a few.
