SS woes continue

Met up with Robbie for a early morning spin. With riding lights it was a dark dusty ride up Beverly Canyon reminding me I want a brighter light. Robbie was having some popping issues with his drivetrain and feeling winded on the ride. His crank loosened just 10 minutes in. He tightened it and we pedaled on only for it to come loose again, this time his crank felt stiff, there was a major friction somewhere and that explained how hard he was pushing, poor guy. He decided to hang back and work on it so I went forward and felt terribe for him.
