I think I have some valid input for this thread. I'm a Steamroller owner and use fenders. I recommend Honjo's. I've used others and the Honjo's are the classiest and most stable. No noise. I'm currently running 32c tires. It all fits. I've had my left knee completely reconstructed twice. You stop counting arthroscopics after awhile because it's like going to the dentist - sure it sucks but you're back to normal soon enough. On that note, I strongly suggest any athletic person needing knee surgery to search out a sports surgeon. If you have a good college football team nearby go there and find out who does them. These men and women return strength and stability to areas for a living. It's all they do. Let them do their job. You can ride with clipless pedals but need to be a little careful. Pain is bad. You'll need to make micro adjustments to the cleats. You'll get there. Just be willing to stop, adjust, ride, stop, adjust, ride for a few rides. I always start new cleats a little loose and let my body tell me where the cleats should set. Not all loosy-goosy but not ratcheted down. I use Shimano's because you can adjust the tension on each pedal. I run the left a half turn lighter. Everyone is a little different. Again, play with it until it works for you. Oh yea, I'm old, too.
