Headset Sealed AC Bearing (45/45 Deg)

The Tripeak Headset Sealed AC Bearing (45/45 Deg) is a precision cartridge bearing designed specifically for headset applications. With India's monsoon humidity, dusty roads from Delhi to Chennai, and punishing heat above 35°C, headset bearings take a beating — this sealed unit is built to resist contamination and maintain smooth steering feel through every condition.

Use Cases

Daily training. Reliable construction for repeat use.

Race day. Lightweight, stiff design for power transfer and aerodynamics.

Fit adjustment. Right stem length critical for comfortable bike fit.

Our Take

Headset bearing quality directly shapes how your bike steers, especially on broken tarmac around Pune, the winding descents near Lonavala, or the gritty roads approaching Ooty. The 45/45-degree contact angle in this Tripeak unit distributes load efficiently across the bearing race, resisting the lateral forces that accelerate wear. At Rs. 795, it is one of the most cost-effective ways to restore precise, responsive steering to a bike that has gone vague or notchy at the bars.

Sizing for Indian Riders

Headset bearings are sized by outer diameter, inner diameter, and width — not S/M/L. Before ordering, remove your existing bearing and note these three measurements, or check your headset manufacturer's spec sheet. Tripeak bearings follow standard industry dimensions, but stacked tolerances vary. If you are unsure, contact Cobbled Climbs with your headset brand and model and our team will confirm the correct fit.

Compatibility Notes

This bearing uses a 45/45-degree contact angle, compatible with most integrated and semi-integrated headset standards that share this geometry. Verify your headset cup's bearing seat diameter before ordering — 1-1/8-inch, 1.5-inch, and tapered standards all differ. Use a bearing press for installation; never hammer bearings into place. Compatible with steel and carbon steerer tubes. Genuine Tripeak product, dispatched from Mumbai.

Pairs Well With

For a complete headset service, consider pairing this bearing with quality bearing grease or anti-seize compound, a bearing press and extraction tool set, headset spacers, and a top cap and stem bolt kit. Keeping a spare bearing on hand is especially worthwhile ahead of the monsoon season.
