Went from a 70mm Thomson MTN Elite stem....pretty much best thing on the market to this 50mm just to make the little bike feel more like the DH rig. Totally did the trick. Actual stem weight with greased face-plate bolts is 147grams...totally comparable to any high-end AM/Trail stem including a 50mm Thomson. THe 50mm definitely looks better than the 65mm, and I don't think I'll ever ride anything longer than a 60mm ever again. At Chainlove $26 price you CAN NOT go wrong. This is an $80 stem and is timeless. Also, perfectly matches my Sunline V1 OS 745mm bars. Perfect width for trail bikes...anything narrower and you're probably slower than me.
