This stem has my trust and is nice and stiff, just the way your mom likes it. If you’re in the fence between this one and a carbon Zipp, get this instead and spend that money on their carbon bars.

This Zipp stem hits the sweet spot for me in terms of quality, price, and sleek looks. Love the shape and torx bolts a nice touch too. Arrived fast and in good condition.
