Starting to come together bit by bit.
I have a feeling the grips will be too far from the saddle for comfort with this setup. Maybe I'll switch out the handlebar as soon as I get a pair of brake levers that can mount to a straight section of bar. I have a porteur style bar (Pelago Parisienne) waiting for this, that I bought to have a second option. (I'll get rid of that ugly RD cage, don't worry!)
