The Fit Bike Co Aitken 1 2011 BMX Bike is an entry level Mike Aitken Signature bike from Fit. While keeping the cost down to meet the entry-level price range Fit have made sure that their 1 series bikes are kitted out with integrated headtubes, sealed Mid BB's and fully sealed 9t cassette hubs making these bikes fully compatible with after-market products to allow easy upgrade in the future as your riding progresses. This Aitken 1 bike is set up to be as close to Mike Aitken's own bike as possible and benefits from 7.75" cr-mo bars, full 4130 forks, Tubular 3-peice cranks and Odyssey plastic pedals.
