"He who marches out of step hears another drum." ~ Ken Kesey
I'd ask for replacements or a refund. 12.5nm is awfully low. I wonder, though, how many people who use statics measure the tension, and how often a company that sells new frames get complaints similar to yours? My guess is seldom. Tension meters seem to be pretty low on most folks must-have list, unless they're using retensionables, because they're expensive. I bought a used one early on because I thought I was going to make my own frames and moved to retensionabes right after.
you know what I'm going to say about this...
Here is another question for the rest of ya. If the 305's need ot be in an area of 20 at min and 22-25 on average, then the 200's need to be at a higher tension right? They are thicker and stronger. Thus able to hold higher tensions. and the 155's? They are at 21? Shouldn't they be up much higher like...i donno, maybe 30-35n?
