Sharon got her first flat of 2012 and first flat in well over 12 months. Not bad at all. She’s running Grand Bois Cypres 700 x 30mm tires. These are fast, supple and comfortable tires with no flat protection. The benefit is she gets the maximum benefit from her pedaling effort and a comfortable ride. So far the Grand Bois are getting less flats than her previous tires that had some designed in puncture protection.
Trouble with getting so few flats is Sharon doesn’t get much practice fixing them. So she tackled the repair in my office so I could provide some advice. She only used tools she carries with her on her bike to ensure field repairs would be possible.
Sharon located the hole in her tube and used that information to narrow down the search for the culprit in her tire. We found some glass that had cut her tire. It didn’t quite go through the casing. We discussed the pros and cons of using this tire vs. replacing it. She had a spare Grand Bois sitting around just for such a circumstance. She decided that since it was a front tire she wouldn’t take any chances and she’d replace it. She kept the old tire and will use it as a rear tire if needed at some point with a patch on the inside. Likely this tire won’t ever see action again as we’ll buy a spare from the Fairfield Bicycle Shop.
It sucks to lose an expensive tire that’s nearly new, but given how little maintenance Sharon’s Surly Cross Check takes to keep working well as her commuter rig this is no big deal.
