I started commuting a year ago, daily about 10 - 15 miles total. I use a folder for commuting because I need to take a train in between or one leg of the journey. Never ridden a road bike before so never done any proper fitting. In the one year commuting I never felt really comfortable. I have done some research and adjusted saddle height, saddle fore/aft etc but gradually I realised the problem is with my legs. I have a slightly longer left leg and my left knee tends to move outward in the up stroke. There maybe other problems or maybe the consequences of something not correct. I am at the point to either cure this or quit commuting by cycling. I see bike fitters are mostly for rodies. So wondering can they help me? Has anyone done that on a folder here?
