Well made and good looking stem
Well made stem- love the black bolts. There’s one thing that could be improved: the print for the torque value is really tiny- a tad larger wouldn’t compromise the esthetics, but would go a long way helping aging forgetful cyclists 😉

Great quality and smooth order process
I’m very satisfied with both the quality of the 42 mm stem and the entire order process. The stem feels solid, well-made, and performs exactly as expected. Delivery was quick and hassle-free. Highly recommended!
