Bicycle Mechanics - head set

What parts does headset consist off? do you have to buy a separate head lock for it?

race crown, bottom bearing, bottom cup to be pressed into bottom of headtube, cup for top of headtube, bearing, cap that covers assembly, and a top cap that attaches to star fangled nut if threadless... sorry i don't know the terminology but those are the pieces from headsets i've worked with (threaded, icbm threadless).

As always, Sheldon Brown knows all and tells all.

And if that is not enough information, click here (http://www.parktool.com/repair_help/howfix_headtypes.shtml) to see what Park Tool says on the subject.

Edited for spelling.

What's a headlock?I know the WWF drill,but not for hS.

A headset will come with all the parts you need, basically the stuff that tFunk listed. Like Pokey, I am not sure what a headlock is. Your LBS can help you.

A headlock is a fantastic part that only costs about £10 from your LBS.
It is a long threaded rod that goes down your headtube and has a nut at the bottom (nicely shaped to fit into the underneath of your fork) and a top-cap, that goes on top of your stem. You hold the bottom nut, whilst tightening the top part with a size 5 allen key. This clamps it all together very tightly. These things are the most secure way of holding all your headset and stem etc together.

use the 'select a manufacturer' part, and choose 'Planet-X'

The headlock should be about £10

:D

Pokey, ya gotta remember these guys are apparently speaking BMX. I can envision that some of the forces involved could conceivably pop a star-fangled nut right out. If I were doing BMX I would probably feel better with something like this Headlock.

Now, to answer the original question in light of this new info. The Headlock sounds like an accessory. It would not be included with a headset UNLESS the same company offers a special headset, in which case they might include it. You just have to ask whoever you are purchasing from.

Well, I ride mtb (dirt, street, messing about) and I bought one because they are so much better than a star nut.

I think the headlock was intended for bmx, however they can be used on any 1 1/8 bike.

You should consider one yourself, the amount of difference it makes, and they last far longer too. :D




btw can a 9speed rear deralleur be fully used on a 8 speed cassette, and shifter?

Azonic makes something that sounds like the headlock, it may actualy be the headlock refered to here.

There are loads of companys that do them. I thought that most bikers used them too!

They are all good, I have an Amoeba. Be sure not to overtighten it though as you will bend the nut on the underneath giving you a bad contact with the underside of the fork. ;)

Stem clamp to the steerer is the holding power in threadless.They are in the QBP catalogue.....What happended to the BMX section?

Doh! Of course, you are right, Pokey, and I knew that. I'm reminded of a little sign my father used to have:

Be sure brain is in gear before putting mouth in motion!
