I'm building up a cross bike to race, commute, and explore poorly paved and dirt roads on. I've got a great deal on a used frame and brakes, my shop will hook me up with a good deal on a fork and, I have an ultegra group to put on it. The crank is a standard 130mm bcd. So my question is, are there any cool solutions for a 'cross rig with a standard crank? I'm picturing a 44 tooth small ring with a bash guard or something. What's the smallest big ring you can put on a 130 bcd?
