Why do I have two bolts under my down tube?

I have finally got my new bike (2012 Trek 6500 disc) and loving it, even though my legs arent yet!!

Looking over the bike I have two bolts, just like bottle mounting bolts and same spacing, but under the down tube. Theyre not for a mud guard because they are at the bottom bracket end - anyone know what they are for?

    Bottle Mount for frames with a small main triangle or an extra bottle for touring.

    Not sure I'd like a bottle there myself but some people do it. I've seen quite a few women's and kid's bikes with a bottle there and found this pic too...

    I reckon the bottle cages down there are more often used to house batteries for lighting systems.
  • that must be it - There is no way I could reach that bottle! lol

    I wouldn;t drink from any bottle that's been in direct spray from the front wheel either. After a wet ride, most of my bike is relatively clean, but the downtube is caked in cack.
  • ill second that! im not putting a full fender on just to make use of a bottle under the frame! lol

    Just a random place to put a second bottle cage mount, which was expected before Camelbaks were invented, and frames became bizarre shapes.
    Before then there was normally one on the seatube and one on he downtube.

    And that Surly has three because, well... Surly make weird bikes.
  • They're for mounting other accesories that use the same spacing as bottle mounts such as pumps.

    The 2012 Treks have three as well!

    You can just see one of the bolts below the downtube here (the other is behind the chainring):

  • Yeah it is a bottle mount - ive fitted my pump to it for now as when I had it attached with the bottle cage you couldnt get at the velcro to remove it! But I've ordered a Fox Lowe Pro hydration pack so pumps going in there once that arrives :D

    Tbh I would have preferred proper crud catcher mounts than a third bottle cage mount!

    Well, at least the cage mounts are useful for attatching things like batteries or pumps.
    Crudcatcher mounts are distinctly less so.
  • I wouldn;t drink from any bottle that's been in direct spray from the front wheel either. After a wet ride, most of my bike is relatively clean, but the downtube is caked in cack.

    That is why for Mountain Biking I only use bottles with nipple guards. Prefer not to be slurping on some mud....

  • You can get bottles that hold tools and fit in there. Handy.

    my genesis core had 2 bolts on the underside but were quite high up the frame.when i put my crudcatcher on it was perfect height as the rounded end of the catcher ran flush with the
    downtube and headtube

    I'm not sure. But whatever one is, hainman is definitely one of them.
