Perhaps only a few of you can appreciate this anecdote, but some time back I sprung for a $50 Stronglight Crank Puller on eBay.
Per ounce, it had to be the most expensive thing I've ever purchased in my life, with the (possible?) exception of my wife's (diamond?) engagement ring.
Anyway, I merilly pulled several Stronglight cranks with it, and it worked!
Then one day while testing my new $10 digital calipers, I measured it, and much to my dismay, I discovered that it was a 23.0 TA Crank Puller, NOT a 23.15 Stronglight puller, and it was just dumb luck that I did not damage those cranks!
- I don't even HAVE a TA crank. Bummer.
Then recently, I saw an eBay listing for a generic,"portable" crank puller, that the seller had found "in the bottom of the box" - for $3.00.
I thought to myself - "Could this be a 23.15 Stronglight crank puller for $3.00"?
Well, it came in the mail today, and guess what?
IT IS A $3.00 STRONGLIGHT CRANK PULLER!
PS- My $10 digital calipers only read to one decimal.
