1 and 1/8 is standard size, most forks come with a 1 and 1/8 steerer tube.

You can also get 1.5's (and small variations around that number), they are bigger. Some forks are now coming with 1.5 steerer tubes as they are stronger. If you pick up a frame with a 1.5, you can get reducer cups to make the frame accept a 1 and 1/8 steerer tube.

That's what I meant. Cane Creek makes reducer headsets too, I've got one of them. Some frames come with really funny headtube sizes and your forced to buy really custom headsets. One of my bikes had a 1.6 or 1.7 headtube with only 9mm deep slottings to fit the headset in.

The 1.5 head tube is not necessarily stronger. The frame tubes need to be larger to get the same weld, so a frame with a 1 1/8" head tube could hold together better than the same frame with a 1.5" head tube.

I was in reference to the steertube/fork being stronger.. not the headtube. But fair enough.

Your calling everything a headtube, its kind of confusing.......the fork has a steer tube, the frame has a headtube. Sorry I couldn't make out your sentence.

i think u need to learn the proper terminology

u can:

put a fork with a 1 1/8" steerer tube on a bike with a 1 1/8" head tube or a bike with a 1.5" head tube (u will need a headset reducer though)

u can't:

put a fork with a 1.5" steerer tube on a bike with a 1 1/8' head tube

u can't:

change the head tube of a bike...

u can:

only put a 1 1/8" reducer headset into a 1.5" head tube
