Even though they would no doubt be small, what advantages are there with a 12mm TA over a 15mm TA, which would have inspired them to create 12mm TA in the first place?
12mm axles and therefore hubs can be made smaller and lighter than 15mm hubs...in cases where the end-caps are not swappable to the larger size. Which some hubs just have swappable caps....many many more do not.
