I thought of your accident when specing my tire size and went with 32mm tires. Very happy about that choice. That size tire grips the ground better than smaller tires and is more forgiving of riding and road problems. My rims could take much smaller tires but I view them as having less of an overall safety effect for the rider. You would have to research where to get such special spokes. Of course start at Shimano first. I just posted the fasted time in years on my Nishiki using platform pedals. I changed out from the SPD's. I going to try for a 15mph real world average speed for rides in the 10-15 mile distance. I'm holding at 14.5mph now so that is a leap but I think doable. I'm looking into more aerodynamically superior clothing and helmet also. The biggest aerodynamic drag on upright bicycles is the rider. California's governor has now mandated that 65+ yr old people have to stay at home. I believe I can keep on bicycling because I always ride alone or with my wife. They don't have any age police out there yet so I'm continuing to ride. Good thoughts, Good health.
