EISH WRONG STEERER TUBE FOR MY BIKE.

[LOSMEICHERIE]

Eish i just bought a shock from cape i never knew steerer tubes are not the same, only to find out the steerer tube is too big for the frame and does not fit on my bike because i was frustrated i went to LBS i was forcing to put a shock on my bike...im in love with the shok its my first air shok im planing to get a frame for this shok the problem is how do i know if the frame is going to fit on the 40 mm steerer tube?

Steerer tubes are straight or tapered?

Which one have you bought?

What does your frame use?

How long is the steerer tube on the fork and how long is your head tune on the frame?

[DownhillingKing]

Steerer tubes come in 1.1/8" and 1.5"

[LOSMEICHERIE]

I bought tapared.

My frame uses straight steerer i only found out after i took it out trying to fit my new fork.

The head tube is 155 mm i hope i messured it right. my bike is large .

There are 3 types of mtb steerers

 

Straight 1 1/8"

Straight 1.5"

And what you bought... Tapered 1.5" to 1 1/8"

 

tapered is fast becoming the most popular standard. In fact, finding new Fox forks in 1 1/8th straight steerer is quite tricky. 1.5" straight is the hardest of all to find parts for.

 

Good news is that you will be able to fit your new fork, just by changing your headset (in fact only just the lower half of it).

 

Now comes the million zim dollar question... What is the internal head tube diameter of your frame. 39mm, 44mm, 49.6mm or 55mm?

Its a maze of sizes and standards out there for bike parts, and one normally learns the hard, expensive way.

 

I think what patches is saying is that you can get an adapter for the lower part of the headset / frame, but the diameter of the frame must be big enough to accommodate the tapered lower half (?) Seem to remember Big Ben has been through this dilemma and got a suitable adapter.

Yup that is what i was implying. If your frame has a 49.6mm or 55mm diameter (internal) head tube, then the lower cup will be easy to find. Most bikes shops should have in stock.

 

However, if you're running a 44mm, then you'll need to do what ben did and get a headset where the lower bearing sits outboard in order to accommodate 1.5". These are harder to find. I know nuke proof made one (available from crc).

We learn everyday.First time i heard about a straight 1.5"

[patches]

Yup straight 1.5 was utilized before tapered. it was mostly used on bigger travel forks.

 

I have a fox 36 talas 160mm that is 1.5". What a pain finding a nice stem and now a headset for my new intense frame

 

 

here's the above mentioned fork on my cannondale. That Easton stem costs a small fortune :|

Looks great though.

All Cannondale mtb's are 1.5" as far as I know - that is what sets us apart

Not if the Lefty is fork of choice.

No, being able to only afford half a fork sets you apart!!!!

Less is more!

I was just telling Patches the other day about a 140mm Fox Vanilla which I got from CRC which mistakenly arrived with a 1.5" straight steerer. I didn't send it back and swore I would find a frame to fit. Still looking...
