Haha, I blew the derailleur off of it on the TLD monthly ride last weekend. The team rider who fixed it so I could ride it home said the same thing. It's single speed at the moment... and the 9mm QR axle flexes too much for me to stand up pedal, chain just pops off, lmao. I am already jonesin' for a mtb ride and it has only been a few days!! Gonna have to settle for dirt jumping the BMX for a while probably....
