Wow thanks for the great responses. The overhead is a must as I fly on smaller 737s and airbus aircraft.

I also just have the tri scenario because when on layovers I usually have the ability to train at least 3 of the 3 tri events so I figured why not lol.

Ive already been toying with the idea of titanium parts idea I just wasn’t sure if anyone here has heard of other ways to make it more road/racer-ish. And I wasn’t sure that the kinetic 11 speed hub would require a fatter triangle. This may obviously effect the fitting in the over head been.

Anyways please keep all the helpful tips coming. Also just as an FYI, I already own a brompton and use it for putting around on layovers, but as you can imagine the upright ride of the M6R combined with the -12 gearing does not exactly give me a great training bike for a little more serious rides.

Thank you all! I appreciate your input
