Quick headset question...

[rainbowarehouse]

Hi,

I've recently ordered this frame:

and these forks:

I was originally going to use the headset from my old bike, but upon closer inspeaction, I can see that parts have been dented in places around the edge from bangs and general carelessness.

After a quick look I found this and was wondering if it would be compatible and suitable?

Going to go for the black one which is on sale at £22 down from £50. There are others that I'm sure would do and are a little cheaper, but I thought seeing as I have no special requirements, I should take advantage of the sale price.

Thanks for looking,
Toby

Imho the best is to ask crc, especially if you are to buy the components from them.

According to this, that bike was supplied with an 1 1/8" integrated VP 41 AC E. But if I were you I would not rely fully on such info., since spec could easily vary by time and location etc.

You might also want to see this.

I'm appalled that most road bikes now use integrated headsets and that most owners seem unaware of the deficiencies of this system.

Then again, at the rate these bikes are used and discarded by younger riders, it may be that they do know but don't really care.

You're going to need a zero stack 1 1/8 semi integrated headset.

Hmmm. Would this do?

I found Cane Creek have a headset finding tool on their website that tells you what kind of headset you need, based on what frame and forks you specify. It said I needed the kind you mentioend, a zero stack, semi-integrated 1 1/8th inch. The problem is, when I look through the various headsets available, I find that they aren't consistently labelled with what type they are. Or at least if they are, they use phrases and abreviations different to those I know of.

Cheers,

Looking at the blurb for 2006 Sub 10's it appears they use a semi-integrated headset

With this type of headset there are bearing cups which have to fit snuggly into the top and bottom of the headtube.

So the all important thing is the internal diameter of the headtube and then getting a headset that fits it.

The only problem is that some idiots then proceed to quote OD or outside diameter as though all tubes have the same width! I have bought headsets based on OD which did not fit and would suggest that you either go to the LBS or try and get a headset that matches the internal diameter.

Is the internal diameter the 1 1/8th number? The headset from Ritchey I linked to is 1 1/8th. Thing is, on Chain Reaction Cycles, the headset is listed with different options when buying as just "Black 1.1/8""then "Black 1.1/8" - 1.5"" and also "Black 1.1/8" OD 46mm".

I'm confused as to why the outside diameter would ever be relevant, seeing as the cups go on the inside??

Thanks for your input,
Toby

The 1 1/8th is the diameter of the steerer (ie the tube on top of the forks).

You do need a 1 1/8th headset.

I have absolutely no idea why they quote the OD - as I say you are better off measuring the internal diameter and then getting a headset that states that it will fit that ID.

The size chart for on the Scott frame page says the headset is "44 SI" which presumably must mean 44mm semi-integrated?

If this is the case I think i've found a headset that ticks all the boxes:

http://www.chainreac...x?ModelID=51070

Relevant specs are:

Features:
• Internal headset
• Deep Alloy cups fit into 50mm OD headtube. ID: 44mm, OD: 50mm.
• Very low profile, designed primarily for ATBs.
• Patented alignment tip for increased durability and performance.
• TH brand 36 degree micro angular contact bearings, 7075 aluminium crown race and aluminium top cap.
• For replacement bearings use part no.160-6475 x 2.
• Colour Black
• Size 11/8"

Can I just confirm that the terms "Internal" and "semi-integrated" are interchangeable and both refer to the same type of headset?

Thanks again,
Toby

The outside diameter of a headset refers to the inside diameter of the head tube. Most common seems to be 44mm but we had a Trek through the workshop t'other day which needed a 41.5mm external diameter zero stack heads set so assume nothing.
