M2
P20 - That is a lovely Stumpy, if thats what emocos is like I wouldnt be painting it.
M2 - Heres what I have found so far.
I stand corrected as the geometry is the same for both S works and Stumpy in M2 configuration.
S works and Stumpies of the M2 variety with the handmade in the USA sticker, which I am sure was all, came out of the same factory in Portland Il, Anodising Inc I think it was. The differences are the S works was thinner walled tubing and the paint was better and was generally tweaked a bit better before it left. This would probably be tighter tolerances and alignment. The thinner walled tubing even with the later gusseting made it a lighter frame. It was towards the end of the nineties that Stumpies made of metal matrix, not sure whether it was the end of M2 or the start of M4, moved from the states to taiwan. S works continued to be made in the states.
I have also found over the years that todays S works design will be a Stumpjumper in a year or two's time. The frame may be slightly beefed with thicker walled tubing but will look the same.
2009 Stumpies are the same. The top two models are carbon and have the same flowing top tube as the S works whereas the two M5 (metal) versions still have the older style. These will probably be the same next year. The Stumpies have a thicker weave carbon similar to a S works of two years ago.
A general rule I have found is that the S works is the XC racer and is harsh on an all day ride whereas the Stumpy is a great all day ride that you can also race.
Hope that all makes some sense as it is past my bed time, but needed to correct my earlier post.
Emoco, is the frame above in P20's post the same?
