Flat Monday

 It was my second flat.

Having already repaired one puncture, this morning I had the benefit of experience, and some excellent patches. I didn't want to give up or postpone my weekday morning ride though.

A simple alternative was obvious. I rode Susan's Brompton.

It's fascinating.

The bikes are absolutely identical other than my bike has:

  • a saddlebag holding
    • a Gerber multi tool
    • a high pressure air gauge
    • a little emergency cash
    • a rag, and
    • a packable back sack
  • a water bottle holder bag
  • a telescopic seat post
  • a RAM X-type cell phone holder
  • a loud bell, and
  • a Brompton tool kit
Individually none of those items are heavy (to be honest the seat post and the Gerber tool are not feather-light). Combined they clearly add weight to my bike. Susan's bike felt... leaner.

Her bike also feels very different. The angle of the brake levers is a little different, and even at maximum extension, the saddle is lower. I understand the saddle height test to be whether, with your bum in the saddle and your left heel on the pedal, you leg is straight. At maximum extension on Susan's bike my leg was not quite straight.

I opted for my short ~7 km ride.

Oddly, I have been having some discomfort I can only describe as tendon pain in my right leg. With the saddle in a lower position, I felt no discomfort. I suspect I have been riding with my saddle a touch too high. I plan to experiment a little in the coming days and weeks to see if lowering the saddle a little might eliminate that discomfort. 

When I got home I had breakfast and tackled the flat.

This time I didn't remove the wheel. I pumped up the tire, found the puncture site, deflated, extracted about six inches of the inner tube at the puncture site, scuffed up and cleaned the inner tube at the puncture site, applied the patch, tucked in the tube, pried the tire back on, pumped it up, and voilĂ  my Brommie is as good as new.

I've had flats on both the scoot and the K75S, both at 45 Commercial Rd, a metal recycling place, bits of steel on the road. Pushing the BMW back to the workshop from Home Depot wasn't a lot of fun.
