Hello All,

I have a Miyata 718a and was wondering if someone could tell me something about it. There's one detail I'm very puzzled over. On the underside of the downtube there is a single "water bottle" like braze-on - but there's only one hole so obviously it's not for a water bottle cage.

The bike has braze-ons for a rack which is exactly what I was looking for. My ideal bike would've been a steel lugged touring one, but . . . . This Miyata is aluminum (alumnitech). Any thoughts on how this bike might handle a load? Thanks.
