This 100mm stem weighs only 99g, saving up to 61g over an OEM stem. These are junk. Fit and finish issues all over, poorly machined, the steerer clamp seems to be overbored, and the bottom of the clamp isn’t flat, applying unequal force on the headset. There’s no particular reason to buy this stem, especially not at full price. Kalloy UNO stems are better quality, and a well established brand. The only reason to buy this stem is because sometimes you can win an auction for one with Ti bolts for the price of Ti bolts.
Price: $27 [High Cost]
✘ Not Recommended
Poorly made, get an UNO ASA-105, 7050, or “7” stem instead.
