Philly’s bestest bike shop Bicycle Revolutions is offering a package deal on a legit fixed / bmx drivetrain. They’re offering 165mm Demolition cranks with a Demolition euro BB and the Volume Krull 130bcd splined spider for $225. Not bad at all! Not sure if they’ll do web-orders, but if you’re in Philly, swing by and check out the shop.
