Ok... I'm still stuck in the past I guess. I remember when everything was a 9mmx110 QR, then the heavens parted and we got the 20mmx110mm forks. At that point it was all easy enough. You either had a QR or a Through Axle... And I've had the 20mm TA ever since. I could swap wheels between ANY of my bikes as needed. Then stupid 15mm came along. It wasn't until the advent of Boost that I even realized that a 15mm TA was 100mm and then the BOOST was 110. Wow, what an advancement... to go from that skinny 100 back up to the 110.... THAT WE ALREADY HAD WITH THE 20mm!! Now to the present. I was looking through Jenson closeouts and I saw a sweet x-Fusion Metric on sale for 60% off. And it is a 20mm!! Score!!! Oh wait. It is a 20mm x 100mm?!?!?! When the @$$%^& did this axle size spawn from hell?
