Crust Bikes Lighting Bolt

The Lightning bolt is a dedicated low trail randonneur frame. Unlike the rest of our frames this one is designed with pavement in mind. Max tire clearance is 650b X 48c. Compatible with both 1X, 2X or even triple chainring set up. Main tubes are pretty thin   walled, which I noticed a bunch of people wanted the Romanceur to be, so here it is.  Will it plane I hear you ask? It flexes in such a harmonic resonance, you will think you are surfing Kelly slaters wave pool riding a Mick Mackie flex tail fish, doing the smoothest high lines this side of Derek Hynd at J.Bay, it just planes that good! What am I talking about I hear you ask? Contact Jan Heine to find out, be sure  to mention Kelly Slaters wave pool, I mean come on people! How is no one else trying to make a bike ride like a surfboard on an artificial wave?
