oh I LOVE LOVE LOVE Spinergy. the company is full of really nice people. they just informed me that they are making rims with disc hubs. so I'm saving up for a set of rims from them. those RevX rims are by far the fastest/lightest I've ever ridden.
of course the 64 tooth Veulta chain ring gives this bike over 160 gear inches. it's just sick fast.
