Just to add my 2c..
On my fitter's recommendation, thought I test a budget stem just to try out the fit.. this is the old graphics..
At the shop, I picked up two stems both marked "110mm", but even just eyeing it, I could clearly see difference in length, so I asked for a metal rule, and sure enough one was just a hair under 110mm and the other close to 120mm, so the longer one must've been miss labelled.. Not trying to put this brand/product down, but just a word of caution...
To my surprise, the weight came out lighter than I expected, 106g for a 110mm..
And with some simple 3T Ti bolts came to exactly 100g, not bad!!
