So, last weekend, dexterq20 and I and a group of friends went to Northstar for some riding, well, dexter didn't ride, he had an ingrown toe nail. The riding was great, I was hitting boondocks drops (6' rock drop) and haulin ass down the double black's. It was great until my chain guide came loose. I didn't know what happened, so I took it into the shop and asked them what was wrong. the people in the shop didn't know what the hell to dohttp://www.ridemonkey.com/forums/newthread.php?do=newthread&f=2, it too them 45 mins to fix it. They thought I was screwed and needed a spacer inbetween the guide and my bb. I got fed up with their stupidity and suggested that they just take out the crank arm a little further and tighten the guide that way..and of course it worked. less than 1 min outside the shop, my chain came off. so, i take it back in to have the crank off. that took another 20 minutes because they couldn't figure out how. gha! The riding was amazing, though. Weather was mid 70's-80's and übersunny. if you're in cali, ride northstar. there is also a bunch of new northshore stuff in lower karpiel. one cool one starts at a tree, goes up right next to it, and goes down curling around the tree, it's pretty rad. moral of the story, the nortstar bike shop sucks.
