Hello my name is Francisco and I am a ciclist from México, I've got a Vilano Shadow road Bike that i've been riding for 6 months. 3 weeks ago I got a Bike fit done at a Specialized dealer. They raised my saddle height from 680mm to 730mm and I changed my 100mm stem forma a 80mm since the reach was toó long after raising the saddle and it hurt my shoulders. My drop from saddle to handlebar went from 2mm to 6cm. Overall the fit was great, I spin the pedals more fluidly, muy cadence went up and muy overall confort improved. But after 2hrs + riding I get pain un my lower back no matter if riding con the tops, hoods or drops. It is so un confortable I need to get off the Bike for 1 or 2 minutes and walk a little. The guy that did the fit said that i hace good back flexibility. I weight 100kg and ride about 120-200km a week. What should I do? Continúe hoping it gets better? Do core exercises?
