Spank X Rainier - Stem Top Cap

What Our Gearhead® Experts Are Saying:

"I didn’t know I needed a beer-inspired top cap until I saw this thing. It's a subtle flex that nods to cold post-ride brews while keeping my cockpit clean and dialed."

Sometimes it’s the smallest details that spark the biggest smiles. The Spank x Rainier Top Cap is a CNC-machined tribute to good rides and cold beers, designed in collaboration with Rainier to bring that iconic bottle cap energy to our cockpit. Whether it’s your trail rig, gravel bike, or daily commuter, this little gem makes every ride feel a little more celebratory.

Crafted from durable alloy and built to fit any standard 1.125-inch steerer tube, it’s the perfect functional upgrade that doesn’t take itself too seriously. We grab one for every build, and a few extras to gift to ride buddies who get the vibe.
