Brain-teaser of the day

Bike tutorial for dummies:how to fit new cleats?

The scene is:

1.New pedals
2.New shoes
3.New cleats
4. Bolt cleats firmly to shoe and clip into pedal to check position and adjust if necessary.
5.Tighten bolts (5-6 n.m)
Nothing can go wrong, can it?
After step 4 I needed to loosen bolts to adjust cleat position.
BUT, when I took off shoe to loosen bolts and adjust cleat, what did I find?
I had stood on a stray ball-bearing on the floor, which had nested very snugly in the head of the hex bolt.


Brain-teaser of the day - how do you remove the bearing/bolt?








The shimano instruction leaflet said nothing about being careful not to step on a ball-bearing before you tighten the bolt.

With luck like that, it's time to dash out and buy a lottery ticket...

Vic has suggested a 10 minute bath in liquid nitrogen to use the different coefficients of expansion of the two metals - ball-bearing and bolt. Unfortunately, he has not come up with a better solution to repair the fragments of shoe than copydex!

You could turn it over in a vice and drill a very narrow hole from the other end!
