The flowers are coming out and we had some rain so it will be a good year for them.

I know I’m desperate went I will ride 22+ miles just to meet a friend for a few minutes, going there in the traffic and riding back in the pitch dark.
Even worse is getting home and seeing your top speed was 53 mph cause you didn’t see how fast you were going… ’cause my Garmin dims after 15 sec.

I having to dress to ride in big temperature swings. When I left home it was 57° F (14° C) and was 39° F (4° C) by the time I got home.

Some days it is just not obvious what caused my flat. I usually look round the area, run my fingers over the area, put in a spare tube and get going again.
If I get a 2nd flat in the same area of the tube as before I will do a really close exam and don’t give up until I figure it out. This time I had an almost invisible, very tiny, metal whisker sticking up inside the tire. It was invisible on the inside and outside. I could feel it with my index finger when the tire was flexed even when I could not see it.
I was able to get it out with a pair of tweezers and a magnifying glass. This the tiniest thing I have ever pulled out of my tires.

An easy to see Austin night road hazard for a change. I managed to miss it…..

Being the rocket scientist I am I don’t need to get slammed more than one time bicycling before I change things.
OK. I hit a piece of road debris going way too fast in no/low light conditions. I missed seeing a small piece of misshaped wood with my headlamp.
I started riding at night on the Barton Creek Green Belt. I have more night riding hours than anyone else I know -years on my mountain bike, years on my road bike.
I would never ride my MTB with a single light, I always had 2 lights. A frame light and a helmet light. One always pointed the direction the bike was headed, one pointed where I was looking.
I could always see what my bike was headed for even if I was not looking that direction – out of my peripheral view.
I got lazy road bicycling and into cutting down weight and stuff. A some point I stopped remembering to take my frame light out on my night rides. To protect myself fully again I am getting back to my roots – 2 lights
How did I hit a piece of wood? I was going 30+ mph. Only wearing a helmet light if I looked away from my path for even an instant I would miss small objects or road surface features.
My new rig:
I have replaced my NiteRider HID helmet light and my NiteRider Halon frame light with updated NiteRider lights. I stuck with NiteRider as I abused them quite a bit over the past 10 years and they held together well.
They are working out great.
The NiteRider Pro 750 is on my helmet and light enough I do notice it. The 600 is next to my helmet.
I run the 600 in flash when I’m in city traffic, where the roads are well lighted or in the daytime. So far it has kept more than a few cars from pulling out in front of me. The flash mode in low to no light conditions will make all the reflective signs on the road strobe with an effect that is very noticeable. People behind me might miss my red strobe tail light, but they certainly notice the entire road flashing back at them. It is a pretty cool effect.

Tour Das Hugel time of year.
I won’t be doing it in 2011. I probably could but I’m not healed from my broken clavicle and it might not be too smart.
Here is the route.
Yes, it is fun. A jungle rules, you are on your own, un-organized ride along a shared route.
Check it out on their web site. Tour Das Hugel.

It does look like I am getting some calcification, so that is nice – that means I am healing.
The radiologist thinks there is no fusion visible since my last X-rays a few months ago. On well, I won’t tell him I’m riding 80 miles a week with light climbing and I am slowly adding more climbing and distance.
Here are the X-rays.
The bones look like a mess…
Along there is no pain and my shoulder is stable I’m starting PT.

New helmet time. My old one goes in the trash. I had lots of miles on it and I am sad to say good bye.
Where do I look first? The Bicycle Helmet Safety Institute to see what is new in the bicycle helmet world. This site has more bike helmet info that anyone ever would want to know.
A few things they believe and comment on for 2011 helmets:
- All the helmets have about the same protection regardless of price.
- Slip-plane helmet with a second shell or liner that can slide over the inner shell should reduce rotational injuries
- Buckles and side pieces–badly need improvement. Most of slip loose too easily
- Rubber or fabric surfaces on helmets potentially increase the sliding resistance of a helmet when it hits the pavement, increasing rotational injuries.
- Rounded, smooth helmet exterior with no major snag points in back that will slide rather than “stick” when they hit a surface will reduce rotational injuries.
Their helmet bottom line: A helmet that meets standards, fits well and is rounded and not pointy is all you need.
My 2 cents:
The more expensive helmets are lighter. A lighter helmet makes a big difference to me when I am riding 10+ hrs a day. 50-100 gms is significant for my neck/back.
Would a heavier helmet be more prone to whiplash? I don’t know.
The current style of road helmets is aerodynamic “looking” with all that pointy stuff of the back, if you fall on the back of the helmet is guaranteed to cause a rotational force on the head and neck. I am thinking the reduction in drag that will not warrant the loss in safety.
Of course there is absolutely no data on cyclists injuries, that I can find, that shows injuries based on specific impact points. This may be a non-issue if it is rare that people fall on the back of the helmet. I always seem to be landing on the side of my helmet.
The higher priced helmets have more vents. I love lots of venting on my helmet. Why? My highest recorded temperature last year was 118° F. (48° C) The high in Austin today will be 104° F (40° C) with the road surface temperatures being much warmer. I need as much cooling as I can get.

You guys know I spent 5 years recovering from a TBI (traumatic brain injury) after being sideswiped by a road raging motorist in a truck. As a result I know more about recovery from a closed head injury than most MDs. I am pretty determined not to get another one.
This crash resulted in no brain injury and from my brain map done post accident, I did not even get a “brain slosh”.
My main point of impact was my right quad – it was the energy dissipation point. It looks like I should of had a slosh, but I did not. There was no rational force on the helmet, it was a flat hit and slide, no neck whiplash or soreness. I got really lucky as other parts of my body were the shock absorber.
I tagged my crash location on this post for anyone interested.
My helmet is now gone. Once they are “used” they no longer protect your head.
Cracking of foam inside helmet:
Helmets are disposable. Mine absorbed enough energy that I my brain was not hurt. It did the most important thing a helmet can do absorb impact and sliiiiiiiidddddddeeee on the road surface. More on that later.
Now I have to find a new one.
