You've seen in the videos how some of the Japanese dudes are already rocking BMX bars in their track bikes, right?
However, putting a standard old school BMX stem (which IMHO generally look pretty cool) in a road bike frame/ threaded fork shouldn't work as they are different size standards, and same goes for BMX bars and road stems, but now there appears to be a BMX-styled stem in normal road/track bike size. Apparently. It looks kinda neat. I want one.
