i can build a PC from a pile of spare parts, but i can't send a fax. seriously, i can never figure those things out

bike repair is best learned through trial and error, and asking alot of questions online and at the LBS. having patience is the most important part. luckily there are tons of youtube videos of guys fixing bikes. I watch them before trying something new. OK, actually i try it first. fail. then watch the videos to see where i went wrong
