RCY RIDE REPORT
Los Pinetos Ride
Sunday
03-16-08
 
It was a chilly morning at the south end of San Fernando Road as 6 of us prepared for the long 7 1/2 mile fireroad climb up to L.A. County Fire Station #9.  Joe, DavidR, DaveW, Matthew, GaryM, and me--all bundled up we began to pedal up the fireroad trying to generate enough heat to battle the temperature that was in the 40's.  But about 2 1/2 miles up the climb DavidR's rear tire "exploded".  We discovered that not only did the tube blow out the sidewall of his Panaracer tire near the valve stem, but the valve cap was virtually melted onto the stem.  While a group effort was made to boot his tire and replace the tube, we also had a mystery to solve as to why this suddenly happened.  In fact, I was going to post a contest to solve this dilemma with a grand prize being FREE cream added to your next coffee.  But as the ride progressed we finally figured out the answer to the puzzle and so the FREE cream is off the table.
 
Using tools and materials in Matthew's 100 pound carry-everything backpack, Gary, David, Dave and Matthew work on the tire.
 
Up, up, and up we climbed, finally arriving at the L.A. County fire station where Matthew's thermometer read 40°.

Wanting to get off the cold mountain top, we began our descent.  But as expected, it was even colder as we descended.  Fingers and toes frozen, we quickly reached the entrance to the Los Pinetos Trail.  The trail had a few ruts and loose spots but as always it was a fun singletrack.  And it warmed up nicely as we lost elevation.  At the bottom the temperature was in the sixties!

We then took what I think is called the Placerita Canyon Trail.  Previously off limits to bicycles, the signage seemed to indicated that the trail is now multi-use and open to bicycles.  It wound its way along a creek, crossing several times, finally bringing us out to Placerita Canyon Road.  From there it was a few miles of pavement back to our cars for a total of around 18 or 19 miles of riding.
 
Matthew, David, Dave, and I continued the tradition of eating after this ride at the alway tasty and homey Saugus Cafe.  Good conversation and food rounded out a fine day of riding.
 
Oh, and for those who are interested in the cause of David's tire explosion, here is what we determined.  David had hung his bike on the trunk rack of his BMW sedan in a different manner than he usually does.  The rear tire (with valve stem at the bottom) was too close to the dual exhaust pipe and so heated up.  The sidewall was weakened which eventually caused the blowout and the valve cap was also melted onto the stem by the exhaust heat.  Problem solved.  So let this be a cautionary tale whenever you mount your bike on a rear rack.
 
Have a great week!
