Bottom Bracket & Headset Service: The Bearings You Can't See

Ask what makes a "full" full service different from a routine tune-up, and the honest answer is two parts most riders never think about: the bottom bracket and the headset. They're both sealed, both easy to ignore, and both eventually responsible for that vague "something feels off" complaint.

What They Actually Are

In plain terms: the bottom bracket is the bearing your pedal cranks spin on, tucked inside the frame where the pedals meet the bike. The headset is the bearing your handlebars and fork steer through, at the top of the head tube. Neither is visible from the outside, and neither gets touched by a wipe-down or a quick brake adjustment.

Why They Wear Out

Both are sealed bearings, but "sealed" doesn't mean "sealed forever." Singapore's humidity and rain work their way past the seals over time, washing out grease and letting in moisture. Ride through rain regularly, or leave the bike stored outdoors, and both components dry out and start picking up play or grit faster than the same bike would in a drier climate.

Signs Your Bottom Bracket Needs Attention

• A creak or click under hard pedalling that doesn't go away with chain lube
• A faint side-to-side wiggle in the crank arms when you rock them by hand
• A grinding feeling through the pedals that wasn't there before

Signs Your Headset Needs Attention

• The handlebars feel notchy or slightly resistant turning at low speed or when walking the bike
• A knock you can feel through the front end under hard braking
• The steering feels vague or slow to respond compared to before

Either set of symptoms on its own is worth a look. Both together usually means it's been a while since either was opened up.

Why These Two Get Left So Long

Opening a bottom bracket or headset properly means the bike goes on a stand, specific tools come out, and the bearings get pulled, inspected, cleaned and re-greased or replaced. It takes a couple of hours and the right tools — which is why most quick services skip it, not because it can't be done where your bike is. We bring the stand and the tools to you and do it at your address.

This is exactly the gap our onsite or workshop guide covers in more detail.

What A Proper Service Involves

• Bottom bracket: removed, cleaned, inspected for wear or corrosion, re-greased or replaced if worn, then torqued back to spec
• Headset: bearings removed, cleaned, inspected, re-greased, and the whole assembly re-adjusted so steering is smooth with zero play

Both are included in our Gold Package ($198), alongside the full drivetrain service and greasing covered in the Premium tier. See the full breakdown on our Packages page.

How Often Do These Need Servicing?

For most riders in Singapore, once every 12 months is the outside limit rather than the target — sooner if you commute daily, ride trails regularly, ride through rain often, or store the bike outdoors. Our servicing frequency guide breaks this down further by rider type.
