Description

The Aurum TH MR042S headset bearing is a precision 1-1/8" cartridge bearing designed for riders who demand smooth, consistent steering through every turn. With a 45×45-degree contact angle, this H1-spec unit is built to handle the lateral and axial loads that Indian road conditions — from Pune's potholed descents to Delhi's long tarmac stretches — constantly throw at your front end.

Our Take

India's roads are unforgiving to cheap headset bearings. The Aurum TH MR042S uses a 45×45-degree contact angle that distributes load efficiently, which matters when you're grinding over broken surfaces around Hyderabad or absorbing repeated shocks on the Western Ghats. For riders who check their cockpit play only when steering goes vague, this bearing is a quiet, affordable upgrade that simply keeps the front end honest and precise. Solid value at Rs. 1,000.

Sizing for Indian Riders

This bearing is specified for 1-1/8" steerer tubes, the most common standard on road and endurance frames sold across India. Before ordering, confirm your headset cup inner diameter matches the MR042S outer race dimensions. Riders on older steel or aluminium frames common in Chennai or Kolkata should cross-reference their existing bearing part number to ensure a direct drop-in fit.

Compatibility Notes

The TH MR042S is a 45×45-degree angular contact cartridge bearing for 1-1/8" headset systems. It is compatible with integrated and semi-integrated headset cups using the H1 bearing specification. Not suitable for tapered steerer forks. Clean and re-grease the cup seat during installation to prevent moisture ingress, especially during the monsoon season.

Pairs Well With

Complete your front-end overhaul with a quality headset press tool, bearing grease or anti-seize compound, stem and spacer kit, and fork star-fangled nut. Keeping these items together means one service session covers your entire cockpit, saving time on future maintenance.

Details

The Aurum TH MR042S is a cartridge headset bearing with a 1-1/8" bore specification and a 45×45-degree angular contact angle, conforming to H1 bearing standards. Designed for integrated and semi-integrated headset systems, the angular contact geometry manages both radial and axial loads simultaneously, making it well suited to road cycling applications where steering precision is critical. The cartridge construction allows straightforward removal and replacement without specialist tools beyond a standard bearing press. Compatible with the most widely used headset cup formats found on modern road frames.

Fitting

This bearing is designed for frames and forks with a 1-1/8" (28.6mm) steerer tube diameter, which covers the vast majority of road and endurance bikes sold in India today. Before purchasing, verify the inner diameter of your existing headset cup and cross-check the outer race diameter of the MR042S against your frame's headset seat. If you are unsure of your specification, bring your existing bearing or headset model number to any Cobbled Climbs service partner for confirmation.
