Personalized, Engraved Bike Chainrings

Speaking of fixed-gear bikes, one of the most fun (and expensive) parts of riding one is customization. That can be as simple as keeping your alleycat road-race spoke-cards in the wheels, or as expensive as buying imported vintage Japanese frames.

Session Sprockets was founded by MIT mechanical engineering student, and the chainrings are milled and engraved in-house. You can choose from two sized rings, standard (130 mm BCD, 48 tooth) or track (144 mm BCD, 49 tooth) for $100 and $110 respectively.
