I totally agree and I don't know why everyone is upset about this. Why aren't all of these people complaining about quick releases too since it's different than 20mm.You have to step back and look at this without your DH goggles on. I reckon the % of XC riders who also ride DH is a lot less than the % of DH'ers who also ride XC. I think as aggressive riding types who have used this "technology" for 10-odd years now, we are conditioned to it. For someone who is a traditional Euro/XC type, 20mm is borderline blasphemy.
All of my riding is on the heavy AM and up side so it has no impact on me. Just as I won't have another bike with a QR, I won't have one with the 15mm.
Think about it though. If you bought a marathon-type bike today it would be with a QR. That is different than a 20mm so why would it be a big deal if QR goes to 15?
Oh yeah, it's because the MAN is out to get us and take our money.
