Each Olsen Frame can be changed by you the customer.  The "base geometry" design is a culmination of all the years designing 29inch wheel geometry.  With tried and tested long-travel 29er geometry.  With a LONG Reach of upto 465mm, ideal for running SLACK angles and LONG forks. We have shortened the Chainstay to 430mm to create sharper handling. This suits both 29 & 27.5+ wheels and tyres. This frameset comes with a replaceable derailleur hanger and a stainless steel adjustable T47 bottom bracket.  It is uncluttered with all cables run internally and only 1 bottle cage.  The rear brake runs externally along the underside of the top tube and down the rear seat stay.  1 bottle cage ensures the downtube is undrilled, holding its impact strength.
