There really is a lot more going on with racks than it would seem. A lot to keep in mind when designing and building them. How are you going to mount them? Are the mounts going to interfere with the function of any of the components like brakes and their cables, quick release skewers, fenders, etc. Can you mount them in such a way that if disaster does strike, the owner can walk into any bike shop and buy a rack off the wall that will fit? Can you keep the weight low and within the wheelbase, and on the the steering axis, over the contact patch, so you're not fighting the weight, so the bike will steer light? Oh yea, can you make them look nice too?
Decided to go with a very straight forward frame design and racks that follow the lines of the bike. Tried to go traditional, but not boring.
I had a really good time making this bike, thinking about all the good times that will be had aboard it. There is something pretty amazing about a touring bike.
