Spank X Rainier - Stem Top Cap

What Our Gearhead® Experts Are Saying:

"This top cap is one of those small parts that ends up getting more compliments than your drivetrain. The CNC finish is clean, the Rainier design is spot-on, and the fit is perfect. It’s a solid upgrade that adds a fun, personal touch to any bike I build."

The Spank x Rainier Top Cap is a finely machined homage to a classic ride tradition: cold beers after dusty miles. Machined from high-quality alloy, this top cap is built to precise tolerances and designed to fit standard 1.125-inch steerer tubes, making it an easy fit for virtually any modern cockpit. The anodized finish and CNC detail elevate what could be a throwaway part into a sharp, functional detail that finishes off a build with bottlecap-inspired personality.

Perfect for riders who obsess over every component or those just looking to add a little flair to their front end, the Spank x Rainier Top Cap is a fun, quality-driven upgrade that ties the whole build together.
