Stem Captain Clock Stem Cap — 36mm Black

The stem cap you did not know you needed until you see it on a bike and immediately want one. A precision quartz clock built into a CNC machined 6061-T6 aluminium stem cap — replacing the stock plastic cap that came with your bike and doing absolutely nothing, with a functional instrument that tells you the time from the cockpit without reaching for your phone.

Clean, purposeful, and genuinely useful for commuters who want to know the time without breaking their riding position. The kind of detail that makes a well-built bike feel considered rather than assembled.

CNC Machined 6061-T6 Aluminium
The same aluminium alloy used in aerospace and performance bicycle components — CNC machined to precise tolerances for a clean, flush fit on any standard 1-1/8" steerer tube. The black base and chrome bezel finish is sharp against both silver and black cockpit setups.

Precise Quartz Movement
A proper quartz clock movement — not a novelty, not an approximation. Accurate, reliable, and running on a standard off-the-shelf battery that you can replace at any pharmacy without sourcing a proprietary cell.

Sealed Weatherproof Construction
Vancouver does not do dry. The StemCAPtain is sealed against water intrusion and mounts with an included rubber gasket that keeps moisture out of the clock mechanism. Rides in the rain without concern.

Installs in 60 Seconds
Unscrew your existing stem cap. Screw this one on. Set the time. Done. Fits any standard 1-1/8" threaded steerer tube.
