http://en.wikipedia.org/wiki/Vernier_scale Wikipedia says Vernier is the correct term. God can't argue with Wiki...

Sorry Verniers. I have a set and use them regularly. Just making the point they always seem to crop up in manufacturing phots. If anyone ever did a photo shoot of my framebuilding, I'd like to eb shown looking serious and measuring something with my calipers!

I love the way all manufacturing style articles always have to have a photo of a micrometer. This article was different from the norm though in that it wasn't being held by some 'engineering' looking bloke in a knowing way measuring something that doesn't need to be measured...

In my experience most mountain bikers are engineers or tradesmen. Very few Doctors or Lawyers!

I'm hoping to sell these frames eventually, so "damn the weight" is not a reasonable argument! Previous generations have been fairly hammered, raced regularly and taken to the Alps, with only minor bending using low spec Columbus Gara tubing. I'm fairly confident in the solution so far, but only testing will tell for sure. I'm an aerospace stress engineer by trade, so know what I'm looking for.

Downtube is plain guage 0.9mm 38mm 4130. If you look at some other photos, I have a doubler under the shock mount. I have bent them slightly on other builds, but with less quality tubing and no doubler. Apparentyl I can get some Reynolds tubing in the same size, but higher spec steel from their motorcross range. I'm going to use this for my next build. But agreed, it is a weak point of the design, and having to spec a large plain guage tube does add a bit of weight. But Im strengthen it up with each new build...

Which tube do you think is going to bend?
