Titanium Bolts question.

Hey,
I'm trying to shed some more weight off my xc bike and I have a few questions about Titanium bolts. First and foremost, are they really worth it? Secondly, I cannot seem to find the ones I am looking for, so I am wondering if they even exist? What I would like is 6 or 12 Ti bolts to replace the standard ones used to mount the rotor to the hub/s on my avid's. Also, if they don't come in a set of 6 what individual ones will I need? Thanks for any help on this!

Don't do it. If you end up with cheap Ti bolts on your brakes, you're asking for trouble. And the weight savings is hardly worth the expense. Crank bolts are a bigger savings, at a lower price. Skewers, bars, seat, and seatpost are the other places to save.

Why are you trying to shed weight? Are you a racer? Or do you simply want a lighter bike because that is the "cool" thing?

Just run three bolts per rotor, that's all you need. And there's no additional cost.

Personally I have left my rotor bolts alone, that is just me though. Some run three ti bolts and three aluminum bolts in their's. Anyway, here is what I did.

Aluminum bolts:
front derailleur clamp, front derailleur cable pinch bolt
rear derailleur pinch bolt
shifter clamp bolts
brake lever clamp bolts
bottle cage bolts
top cap bolt (tighten with steel bolt then replace)
Chainring bolts

The only titanium bolt I went with was the seatpost clamp bolt.

Here is the weight differences between them, not including the chainring bolts.

I have that same scale. As far as hardware goes, depending on the age of your components, you can probably get a Ti pivot bolt for your rear derailleur. A good thing to have, and saves weight too. But Lowcel is right - you won't save much weight.

PM me if you're interested in the spare lightweight bits I've got floating around here.

They also make an aluminum breakaway bolt for the rear derailleur that is pretty nice and light.

Boy I would love to pay lots of money to save another 20 grams off my bike. Just take a dump before you ride, free weight savings. Have you replaced any braze on bolts you aren't using with plastic ones yet?

Actually I have plastic bolts for my bottle cage bolts (no bottle cage).

As for the dump I do that as well. On top of that I try to watch what I eat a little more closely leading up to a race.

As for the money, some people don't mind spending extra money on things they enjoy. You don't have to like it or understand it.

On a final note, you may want to check your math, it was actually 31 grams.

I don't see any reason to impose your personal budgetary constraints on anyone else, especially since the OP didn't mention cost being an issue.

I pull the braze on bolts and seal the holes with a dab of RTV sealant. I'm not sure of the weight savings vs. plastic bolts though.

If you are willing to piss away good money on useless stuff then sure. Saving 30 grams WILL NOT make you a better rider period My 33lb "x-country" bike takes me past most of the riders in my area, you know why?

Yup, we can all only dream of being half the man he is, or at least half the man he "thinks" he is. One of these days us mere mortals may be worthy of being on the same forum as him, and all of his "vast" knowledge.

I agree completely, however 30 grams here, 50 grams there, 25 grams over there eventually adds up.

They exist... here

Not too much weight savings with the rotor bolts though. When I replaced every bolt on my bike with a Ti or aluminum bolt, the total savings was about 60-70 grams.

PS. I really don't understand the hate to the people who talk about weights. I'd appreciate if someone could explain why.

Most people don't understand that it becomes a hobby within it's self. I know that a light bike will make me faster, not necessarily enough to make up positions in a race however sometimes there is only a difference of a few seconds so who knows. I do realize that saving a few pounds, never the less ounces on a bike will not take someone from being a mid-pack racer to a podium finisher. I think that some people believe having a light bike will work miracles, it just doesn't happen.

With that said, most of the time I'm trying to save weight on the bike it is because to me it is fun to have a light, reliable bike. It is a challenge.

Little bits count in large amounts. I apply that to many things in life.

I am not a weight-weenie but I do not get annoyed by what other people enjoy. I'm sure there are many that would question why anyone would spend so much on a bike when any old Huffy Wal-Mart bike would do.

Some people have money....some do not. Why impose your bitter attitude to those who have some to spend on the things they love?

The cold reality is that, in an XC race, a guy who would otherwise be the exact same speed as you WILL beat you by lightening his bike, every time.

I realise that two guys having exactly the same time in a race is unlikely, but why make things more difficult anyways?

But is it worth it? If you are obsessed enough with weight saving, them you have to go the distance: Get a speadsheet, put in the weights for everything, the costs for everything, and the math with speak for itself.

That said, I haven't done any bolt-changing since the 90s.. mostly I just screen for mysteriously heavy parts and try to replace them. There are always a few boat-anchor parts on my bikes that need swapping before I ever start counting things to the gram.

Ever lost a two hour race by less than five seconds? I have, it sucks!!!

However, in that case it wasn't a little weight that got me, it was not having the kick at the end that the other racer did. He wanted it more than I did that day, he earned it.

Wow, thanks for all the responses guys, I appreciate it. I think, for now at least, I'll just do the 3 bolt thing for the rotor. Some unexpected problems arised last night that I need to deal with now {couple spokes popped out due to stripped nipples** so I have to cover that first. I will probably end up doing a complete spoke/nipple overhaul. I want to swap out my straight spokes for some double-butted {hey, that saves me like 70 grams per wheel**.

You could use titanium spokes!!!!!

Ah, but should your bike have been lighter, you could've had just the right amount of kick to take the finish. You would've saved energy for the whole race and you may have been enough ahead that his kick at the end wouldn't be enough to take it.

Just think of all the energy you save going up hill on a light bike v. a heavy one.

Of course, everything would've been different though so no way of knowing what would've happen.

Some of us just have extra cash to piss away on bike and other things. I spent over $10k on a camera, not just as a tool for my business, but because I enjoyed owning and using such a precision tool. Others may want to spend money on a big screen TV, which is a waste, in my opinion. I just don't see why people need to be so critical of how others spend their discretionary income. We built a titanium tandem, but I still put food on the table, and a roof over our heads. Get over it.
