Blowout at 46.25mph

December 6, 2008 · 8 Comments

What a great day for a ride, it was nearly 70 degrees and for the first time in awhile there wasn't an obnoxious amount of wind. Just a great day for a spin. I had to take Zeb to his skating lesson, which he passed Snowplow 2. Next was the leaves, I got those mowed and mulched. Finally around 3pm I was able to hit the road.

I got everything ready, turned on the Garmin Forerunner and as it turns on it starts freaking out about low batteries. I turn it off, take it inside and plug it in. I don't need it, the PowerTap keeps track of everything but the route. Finally I shoved off and the first few pedal strokes I hear a weird clicking noise. I unclip a few feet from my driveway, narrow the noise down and find a staple sticking out of the rear tire that was rubbing when the tire rotated. I pulled it out, luckily it didn't seem to puncture the tube. Off again, heading down Anderson Mill to Limecreek for a down and back to Volente Beach.

Heading down the 3 Sisters I get into an aero tuck, I'm flying down the road. My goal is to not touch the brakes at all on the decent. At the peak of my speed near the bottom of the sisters it happens. There is an unmistakable sound of metal clanking, however it sounded oddly familiar, but in the heat of the moment I couldn't place the sound. In my peripheral vision I see something, a spoke flying off perhaps. In a matter of seconds the air in my front tire was out and I was rolling on the rim.

If you know the sisters, you know at the base of the hill there is a sharp turn to the right. There was no way I could make the turn on the rim, I quickly glanced ahead to see if I was about to be struck by a car coming the opposite way or if I needed to pull the emergency shoot (i.e. take my chances with road rash and hope I didn't roll into oncoming traffic). Good for me there was no cars coming, so I kept it straight and came to a stop in the dirt.

I checked to see if I had a spoke sticking out of my leg, negative. I then looked over the wheel, no broken spokes. I set out to change the tube, a fellow biker rolled by, asked if I needed anything. I thanked him and said I had it covered. With the new tube in place I pulled out the CO2, twisted on the quick inflator head, but no air was coming out. Gave it a couple shakes, twisted it, but no air. Untwisted it and low and behold it was empty. SHUCKS!

About this time the thoughtful rider came bombing down the hill, he didn't slow. Can't blame him as I had just told him a few minutes prior that I was fine. So there I stood with no air I was about to succumb to defeat and call the wife to come get me. I call and get "the machine", everybody is outside! The good samaritan comes back, I flag him down, he gladly offers to let me use his frame pump.

I get it pumped up, it feels firm. Good Samaritan says he has a PSI gauge. He digs in his bag and pulls it out, he slaps it on and says I only have 60 psi. Darn that's not enough. I go back to pumping, man my arm is getting tired and then it happens... The valve busts off and shoooosh, out goes the air.

Once again I have to phone home, again the machine. I start walking up the Sisters, it's only 3.78 miles from the bottom to my house. I get to the Fisher Hollow Rd and prop the bike up against the mailboxes and walk down a bit to see if I can find what I ran over. On the side of the road I find the culprit.

Tape Measure

A broken tape measure. The yellow metal tape was broken into 2 or 3 sections. I think this is the section I more than likely ran over and it explains what I saw in my peripheral vision. It also explains the familiarity to the noise I heard. Finally I get ahold of Jennifer and the SAG wagon is on the way.

It was a great day for a ride, but it wasn't in the cards for me. Hopefully tomorrow will be a better day for a ride.

    The scariest thing to me was that it happened to your front tire. That can really lead to serious problems. It's a little easier to control the bike on a rear tire blowout. I would not want to have to make a split-second decision to shoot across an oncoming traffic lane. Glad you're all right.

    First, I'm glad you didn't get hurt flatting at that speed. Second, your story of failing to get the new tube inflated reminds me of one of my mornings. Hope your next ride is better.

    My heart rate went from 90 to 128 in the 11 seconds from the blow out till I came to a stop.

    Mike, happy to read that you stayed upright! This is always in the back of my mind when I go down the Sisters. I recall seeing a video on YouTube that should give your readers some context of what the hill is like:

    @Randy Thanks for the youtube video link. When he calls out 47 mph thats about where I blew out. I have a really bad youtube video from an overcast day of going down and back up the Sisters: http://www.youtube.com/watch?v=VX4-uVZ4pAc The other video is better in quality and shot on a nicer day

    Great post. Tumbleweed Hill, 360 down to the lake, etc., I'm always thinking "what if i have a flat?" It's amazing to read what went through your mind in a matter of seconds, and that you were able to make a rational decision!

    Wow! I'm just getting caught up on your blog and see this! Glad you are in one piece after that! I also don't know how I missed you, but I now have you linked up on my blog.

    Holy crap! Glad everything worked out - a front tire blowout on that descent could have been... well, interesting.

    One day last year I had 3 flats in the same ride. I carry one tube and one CO2 :)
