    Does the Mojo HD frame have a drain hole?

    Been riding my 2012 HD for 6 months now and it just dawned on me that every time I wash it I could be introducing small amounts of water into the frame. Anyone know if the frame has a drain hole anywhere? I couldn't find one but hey it could be hidden.

    Huge 31.6 hole when turned upside down. But that's it.
    Those who know, ride a Mojo AND a Mojo HD.

    Hey now there's an idea. I wonder if Ibis can make a transparent frame so I can watch my goldfish while I ride.

    Haha, a while back someone posted here that they pulled their post and turned over the bike after a long winter and instantly shaved about 12 oz of (fluid) weight...

    After washing or wet riding, always remove the seatpost and flip the bike for some minutes. I've found some very rusty headsets bearings because this issue, either HD's or SL's.

    On a more serious note, this is very good advice.

    Carbon bits and frames, gives galvanic corrosion galore, once water is introduced to the formula.

    Steel and aluminum, will see a lot of corrosion, if they are wet and around carbon.
    Titanium and stainless steel, is not an issue.
    Anodized aluminum is mostly ok, as long as the anodizing is not broken through.

    Back when I made my first set of carbon cranks, I thought galvanic corrosion would not be an issue in reality, for at least a decade.
    After 8 years, I was proven sooo wrong, as the aluminum inserts simply fell out.
    For bearings, I would think less than a season, perhaps even a couple of months, will be enough to kill them, if in a wet carbon frame.

    From what I remember the Bottom Bracket is actually isolated from the seat tube. so the water that poors out doesn't actually hit the BB area.

    May want to confirm this with Ibis.

    My mojo c doesn't have a drain hole as well I guess that is apparent to all ibis frames. I always remove the seat post and flip it after every wash.
