That’s right, upgrade with aluminum

The stem’s trusty two-bolt steerer clamp and four-bolt handlebar clamp are built to handle the toughest rides and utilize a simple design to save weight. The Nine Alloy stem features a bead-blast black finish for added durability and it’s available in four different color options and sizes.

  • Familiarity: I've used it several times

Correct length, angle, and light weight for the bike build I did this winter. And the matching green trim available in the niner stem and seatpost sealed the deal. Going with 4 stars here because you can get similar specs on a Thomson stem yet Thomson has a couple decades of bombproof reputation behind them. Kudos to niner for offering multiple trim colors though?makes subtle ?customization? of bike builds possible.
