Just got a Specialized Langester Pro, that came with some American Classic 420 Aero wheels.
I'm having an issue securing the rear wheel. It has a bolt that an 8mm hex wrench is supposed to fit... However my Park Tool basic hex set does not fit this properly. A guy running my local track advised me to go to a hardware store and find threaded 15mm bolts to replace the 8mm hex/bolts that came with the bike.
Last time at the track I thought I got it tightened down properly with my park tool hex. However today, after riding about 10 minutes of laps, I took a break to adjust my seat and got back on my bike... 50m down on the track and my rear wheel came loose.
I went into the track's shop and discovered a pedro's 8mm wrench, that fit like a glove. Hopefully next time I go to practice my wheel won't come loose.
In short, my question is should I try and get a 15mm bolt, or just tinker with the 8mm?
This sounds a bit obscure and pictures may be in order... next time I go to the track I'll take some.
