Sram - omnium track crankset
So I'm new here and found this forum through some research on things in the past few weeks. So I come from the BMX world and decided to leap into track bikes as well. I decided to go with a State Bike CO complete bike. It was in my price range even thought it may not have the greatest parts. Anyway to the question... I wanted to buy the SRAM - OMNIUM TRACK CRANKSET and wanted to know if the bottom bracket it comes with will fit my frame. On the state bike co website it says the bb is 68x103mm. Does this mean anything? It came with sealed cranks but they suck and I'm a pretty big guy and want something stiff. The Omniums seem to do the trick after all the reviews I read about it. Can anyone help me with this? I plan to call up State Bike Co in the morning and ask them about it but I wanted everyones take on it here. Thanks and all help will be greatly appreciated.
