I am thinking of using a system where I can use front wheels that are 700c - making parts etc interchangeable. I am thinking I will HAVE to go for 2 wheels as I will be carrying a decent amount (incl sleeping bag and blanket for staying at friend's places) - Is it possible to slant the wheels so the tops are pointing inwards a little bit for improved cornering ability? I will be putting some nice tyres on them, the same as on the bike so that it all looks good, and I know that they will last longer than the ones on the bike.

Can someone describe how you atatch front wheels to the sides?

I have yet to decide on mounting with seat post vs QR axle mount (seat stays are not an option as I have minimal clearance with my size 47 shoes)

And any comments on gearing?
