Speaking of the bike, I modified another thing on the Raleigh Twenty since my accident. I cut the end off some pedals, one of which already had the end broken off. This made them about 3/4" shorter than the folding pedals that were on the bike. This will make them less likely to come in contact with the slanted face of the levee, should I ever try that again. I tried the bike out by hand a couple of times while on my ride to check the clearance. Right now, it looks like if the uphill pedal is at the bottom of the stroke, it might just barely touch if the bike frame is perfectly upright. If I try this out while riding, I plan to walk it down the face, then ride it at the bottom of the face and maybe try climbing back up.
So now the changes I've made are
- Put fatter (50x406) tires on the wheels to lift the bike frame about 0.3".
- Replace the rear fixed gear wheel with a coaster brake wheel which 1) allows me to coast and 2) gives me a rear brake.
- Reduce the width of the pedals by about 3/4" which should help hitting the pedal on the sloped surface of the levee.
- Change the wheels to 451 rims. I think this would cost between $100 and $150. This would only raise the frame at most about 0.7" since the tires will get thinner. So not yet.
- Change to a 140 mm crankset. I currently have a 165 mm crankset. I've used the 140 before on another bike. The effect of it is that it is harder to pedal and really, the bike needs to be geared down and then pedaled faster. That's possible but not desirable.
I also have to give credit to my wife. She doesn't discourage me at all from going back out there and frankly confronting my fears. She just asks for my expected time to get back home. And fortunately, she's somewhat trained by ultrarunning where I would underestimate my return time from workouts by hours.
Finally, I'm pretty happy with how my body responded to the crash, if not how my legs respond to pavement. I felt like I was in a mental fog for about a week which is a lot better than what others report after a concussion. At least a couple of things actually improved. Sudoku seemed like a little different game and now it looks like I have improved at it. Also, I got rid of the bad habit of chewing my nails. I think my beat up finger was the first thing that stopped me biting my nails, but now my dental hygienist told me that I have a crack in my tooth, so I've put a definite stop to that.
