That's what you have to say when you're mounting (or dismounting) 700c tires on Ambrosio 19 rims.
I've done this a few times before, and it's not pretty.
In fact, just this evening, I became so fed up with it (snapping two tire irons and destroying the bead on two tires) that I decided to spend some money on a substitute rim, and naturally, the first thing I wanted to know was the ERD.
Lo and behold, the Ambrosio 19 is listed on Spokecalc as a 27" rim !
- Not surprisingly: 700c tires mount as if it was a 27" rim.
- But an Ambrosio 19 is a 700c rim. -Isn't it?
- Velobase lists it as a 700c Rim - but then again, I would expect a 700c rim to have an ERD of about 612, not 620!
I have had two bikes with Ambrosio 19's, and BOTH came with 700c tires.
Wot the hey?
There is nothing on the rim itself saying one way or the other - 700c or 27".
Which is it?
27" or 700c?
Despicable or Loathsome?
