Again that would mean that either the Waterford drawing is incorrect or they weren't made as precisely as we would like to believe. I think when you are dealing with hand-made components the latter is more likely, but only Waterford knows for sure in this case. The drawing referenced the HTA/STA off both the TT and dropouts (and both are the same) so one is correct while the other is not. It sure would be interesting to hear Waterford's take on this. Maybe the spec. was revised between the drawing and actual production? Maybe they just had a fork and/or headset that worked closely enough without matching the drawing exactly and didn't think people would be trying to measure things so precisely in the future?
