Hey everyone, i used to ride bmx but ive recently just bought an onza comp 09 model.. it rides ok on the control side of things but it kills my shoulders to get up walls or benches, like the geometry is all wrong for my size as im 5ft11? I tried adjusting the bars which made it abit better but not great.. is there any tall mo'fos out there that know of a good bar and stem set up for a tall guy on a 20"? And would making it longer with curved forks help make it feel and ride better too? any info welcome.. thanks in advance, Rob.
