Can't find the guide for gear/shifter cables @ Park's repair blog, garage sale GT.

Learned some things today on a test ride with our two bicycles.

1) The bicycle pump I purchased from that retired professional cyclist absolutely sucks.
2) The rear LED blinkers are inconsistent in quality - the one I mounted on my wife's bicycle tightened just fine, but the one on mine will not tighten much because of a defect.

Also, I installed the bicycle wall mount upside-down. Haha!

I am having trouble finding 27" tubes. I would like to get 27" Prestas. And what is the width? 27xWhat?
