If this is the case, just give the top of the steerer tube a tap with a rubber mallet:Īs you remove the fork, you’ll see there are several parts to the headset, both above and below the frame’s head tube. Sometimes it does it’s job a bit too well and the fork gets stuck in the frame. Part of the headset is a circular wedge, or compression ring, that fits snugly around the top of the steerer tube. Simply loosen the two bolts that clamp it to the fork, and slide it up and off:Īt this point, the fork will be free to slide down and out of the frame. In order to get at the headset bearings, you’ll need to remove the stem completely. When tightened, it pushes the stem down against the headset to compress the bearings: This bolt threads into a star nut which is wedged inside the steerer tube. It’s simpler, easier to install and maintain, and doesn’t require anything more than an allen key to take apart. This is a more recent design and has become very popular on modern road and mountain bikes. The stem clamps directly around the steerer tube and is simply pushed down against the headset bearings to provide compression. The top of the headset is a large lock nut which threads onto the fork, and when tightened, sets the compression on the bearings. A threaded headset, surprisingly, uses a fork with a threaded steerer tube. There are essentially two types of bicycle headsets threaded, and threadless. Now it’s time to take a look at the headset, the set of bearings that allow the front fork to rotate freely in the frame. I pulled the crankset, removed the bottom bracket and old brakes, and gave the frame a thorough cleaning. Last time, I stripped most of the old parts that had been beat up from 2 years of all weather commuting. I’m working on overhauling my commuter bike, a Montague Boston, and making it truly custom with all new components. For me, I want to know every part of my bike inside and out, know what makes it go, and know how to take it apart and put it back together. Sure, you can have a bike shop do maintenance for you, and if it’s a big job requiring specialty tools, this might be a good idea. If you’re anything like me, working on your bike is half the fun of owning it.
