I swore I had one....then I looked down to see it blow away on my ride today...so I chase it down and try to insert it back into my spokes. It fell right back out. Now, being the brainiac that I am, I noticed two absurdly loose spokes...should I just tighten these myself or does tension and all that matter so much I should take it in to the LBS? My bike feels naked without my card from William Karsten on it.....
