I'm thinking of getting some titanium bolts for my bike. No real reason other than I think it would be cool.

What are your thoughts on switching out? I would likely just leave them plain metal, none of that rainbow nonsense. I've been able to source some bolts to replace the front disc, gas cap bolts, front faring bolts and the engine cover bolts as well. Anything I should consider when replacing the front disc bolts (i'm looking at grade 5 titanium)?

Ti is softer and would allow as much preload. I recommend locktight on fasteners that have a higer torque applies that you don't want falling out.

Is it boring in Canada :naughty:

Do a forum search on user name Perfect. He replaced just about every fastener on his F3 with coloured Ti. He did a lot of research as to what grade was needed where. Somewhere he posted a list of all the fasteners he switched out complete with those that had to be cut down.
You’ll find photos of his master work like this one;

It's important to make sure that when you replace high tensile strength bolts with Ti, that you go over rather than similar in strength. Do a bit of reading http://faqload.com/faqs/bicycle-components/bolt-tuning-replacing-heavy-steel-bolts-with-titanium-aluminum-and-carbon-fiber and make sure you get it right.
We've recently had a rule change in the racing regulations, banning Ti bolts and cap screws in brake callipers and disc, simply because the guys where buying cheap Chinese knock-offs and endangering everybody around them.

I'm not saying you shouldn't use Ti, just saying you should familiarise yourself with what you're planning on doing, for your own safety .

Good point Donsy. Another thing that should be considered is “galvanic corrosion” caused by dissimilar metals. May not be an issue with hard plated Ti fasteners that see very little inclement weather. However, harsh cleaners used over time can act as an electrolyte.

Dons is absolutely correct. You need to make sure the bolts you are replacing are as strong or stronger than ones replacing it. NEVER trust the manufacturer on some BS "Aircraft grade" or "high strength" because you need specific measurable values, which are seldom ever reported.

You can see on this page they give you a specific strength
minimum tensile strength of 50,000 psi, a Class 2A thread fit, and a minimum Rockwell hardness of B80. All meet ASME B18.3.

[del]This site has no strength allowable posted and only a bullsh!t marketing gimic to make you think it's a good product[/del]
'Race-Spec'
If you're buying fasteners, buy from a good supplier like the first one.

Thanks for the links and info.

Lots of great info from everyone on here. Definitely why I posted on this forum. Looking at the prices and understanding what goes into it I understand that you're paying for what you get but I'll probably fore-go the titanium bolts on the critical bits for now as it was just a mini project for me over the winter months.

timpants,

Your statement above is very very wrong.

For your information Probolt are one of the top suppliers of fasteners to a large number of UK BSB race teams and are renowned for only supplying top quality material.

I personally know the owners of Probolt and have dealt with them for all my fastener needs for many years, the stuff supplied is superb, I track my MV's and will not skimp on shoddy kit.

If you have any questions on quality and integrity in their supply chain I suggest you e-mail them and they can provide you and others with documented evidence of the very high standards of the fasteners they supply.

Hasn't Randrew spent a fair fortune on Ti fasteners?? Pretty sure he has purchased from ProBolt, too.

It costs an awful lot to reduce a little bit of weight......

Hi Ed,
Yep Randrew, and a good few other of us have purchased from Probolt, my F4 750 has around £1,500 of Ti bits from them on it and the fasteners are superb stuff.

Did I save a huge amount of weight, nope, but it sure as hell makes me feel good.:)

Oh, I found the link to their spec sheet at the bottom of the page. Their values are a tad low but for johnQpublic they are fine. I stand corrected.
