I have 3 bikes and they are all singlespeed. My main commuter is a KHS fixed gear, with full fenders, front and rear racks. My other ride is a Surly 1x1 which I also run as a fixed gear with 700cc wheels, my Surly is my most favorite bike, it's my do it all bike, if I only had to have one bike this would be it. I have few other wheelsets for my surly, all 700cc and SS, this bike also has full fenders and a medium sized ,#139 wald basket on the front. And then I have an old RM Vertex (2006). This is the bike that stared it all. When I first started commuting in Sept,2007 this is the bike that I used. I made a lot of changes to it. Got rid of suspension fork and installed a rigid fork, got rid of all the stickers and painted the frame flat black, converted to SS, added full fenders and front/rear racks and drop bars. My RM doesn't see as much use as before, but I still use it for winter trail riding,
I keep it as my emergency back up bike, it's all banged up, scratched, ugly.. but very functional.. Damn ! , I need to buy a camera and start taking pics.
