Just for the sake of being ridiculous......it's pretty pan flat out by my work. I'm interested in trying out a fixed gear. Does HED or someone make an 11spd/fixed hub kind of part you can swap in and out? So you can own a single wheel for TT and for track? Or is this a fool's errand?
I see kits online, but it looks like the college student hipster kind of crap more so than what I'm really after.
