Spank X Rainier - Split 35 Stem

What Our Gearhead® Experts Are Saying:

"This collab nails it for riders who want their components to perform and tell a story. The Split 35 is already bomber and light, but the Rainier touches make it one of the most unique stems I’ve ever run."

Forged in the PNW’s misty forests and shaped by two iconic names—Spank Industries and Rainier Beer—the limited edition Spank x Rainier Split 35 Stem isn’t just a cockpit upgrade; it’s a celebration of trail culture. Designed for all-mountain, enduro, freeride, and E-MTB applications, it combines high-performance geometry with custom aesthetics that pay tribute to Rainier’s rich Northwest legacy.

Precision-milled from 6-series alloy using Spank’s 3D forging and CNC-optimized processes, the Split 35 offers a light yet stiff structure that holds its line under aggressive trail inputs. Its chamfered bar clamp interface reduces stress risers and extends handlebar life—critical for carbon setups—and the ultra-short stack height supports low-slung, modern front-end builds. Zero-degree rise and a 35mm clamp diameter maintain responsiveness and keep cockpit tuning seamless.

The stem features laser-etched tuning guides to help you perfect upsweep and backsweep for your riding style. It also ships with both titanium gold and chromoly black bolt kits, letting you dial the vibe to match your frame or component color scheme. Whether you’re shredding Bellingham brown pow or cracking a post-ride cold one, this stem speaks to the rider who lives for fast descents and local pride.
