You've probably heard about that velodrome in Detroit that was revived by a group called The Mower Gang. Or, maybe you haven't. Either way, some enterprising fellows are holding a race for geared road bikes, fixies, mountain bikes, powered scooters and mopeds at Dorais Velodrome and using the proceeds to restoring the place by putting 50% of the profits into upkeep and giving the other 50% to Detroit Parks and Recreation.
Presenting, The Thunderdrome!
The classes and concept are awesome, including a Le Mans-style start for everyone. And no, you and your NJS-spec Gan Well will not be rubbing handlebars with some fire-breathing 50cc scooter. There are different classes for all the aforementioned bikes above. If you are anywhere nearby this event on the 16th, please go check it out. C2D will pay handsomely for coverage of this event in riches of unrelated used bike parts.
PS - more pics and a vid after the jump.
