I want to replace the mounting bolts on my Avid BB7's with Ti, where is a good place to get ti bolts?

Try Tastynuts.com they ship worldwide and have a huge sellection of titanium and aluminium bolts, nuts, washers in many colours.

I have ordered from them several times and they are very good to deal with.

They are in Canada...fast service and shipping was about 1 week to MA.
Great prices and selection...and they do blue or gold ti if you want it for a small upcharge.

You can email them about the mounting bolts.

Hi im new to this Ti bolt thing...

What is the difference between Ti bolts and regular ones? what would the weight savings be? if any

Thanks
Jimmy

a Titanium bolt vs a Steel bolt of equal size and length is approximately 33% lighter.

And aluminum bolts....

a Titanium bolt vs a Steel bolt of equal size and length is approximately 33% lighter.

are 1/3rd the weight of steel. Then again, you don't want to use them anywhere critical with a lot of stress like stems or brake calipers.

Also, alu bolts are way cheaper than Ti.

Alum vs Ti

a Titanium bolt vs a Steel bolt of equal size and length is approximately 33% lighter.

Naturally then, what is the difference between Aluminum and Ti?

 

[ddakin]

Aluminum isn't much heavier than Ti, but doesn't have nearly the same strength. Alu is a really bad idea anywhere requiring strong bolts (i.e. stems).

Comparison of specific gravity of metals (alloys will vary a bit). The specific gravity of a material is defined as the ratio of its density to the density of some standard material, such as water at a specified temperature, for example, 60°F (15°C), or (for gases) air at standard conditions of temperature and pressure. Specific gravity is a convenient concept because it is usually easier to measure than density, and its value is the same in all systems of units.

Aluminium 2.6 - 2.8

Magnesium 1.738

Steel 7.8

Titanium 4.5

So for objects of the same size and shape made of these materials, that's how the weights would compare.

back to basics

So while we are reviewing the basics on this one, how about a rundown of the bolts that would be reasonably safe to replace with aluminum.

...Which then raises the question for me about the extent to which stock components (e.g. XTR's) come with alum bolts already (and why/why not)...

components w/alloy bolts

thanks, that takes care of the first question really well... the others?

A magnet will identify those mystery bolts on your XTR.

Al bolts - dérailleur clamp bolts, brake lever clamp bolts, shifter pod/lever bolts, headset bolts and chainring bolts
Ti bolts - everything else
