Yes it does

Yes, there is galvanic potential but like I said, it doesn't seem to be an issue elsewhere on the bike. Upper end Campag and Shimano components are full of Ti bolts and grub screws and I don't ever find the seized. Hence my speculation and looking for other reasons. Maybe AC is just playing it safe, who knows? And, since it is only speculation, I just took the MPa for the most common Ti alloy, the one with Aluminium and Vanadium. I wish warnings would come with reason, so that we know how we can ignore them.

You're right. Thanks. I always say that Ti is approximately half as strong as steel and twice as strong as aluminium, but that leaves me open to the definition of strength. I got the 79300 from a spec sheet I have here for a brand of hi-tensile bolts.

Edit: Sorry Stretch, I read can, not can't. I will clean my spectacles now.

Why make life so complicated? This Kalabash oke is really stupid.

I don't think the issue is corrosion. Ti is successfully used as bolts in many other bicycle parts without any issues at all. I think it has to do with Ti's weak shear strength, compared to steel. Disc bolts are constantly subjected to shear forces and Titanium (depending on the specific alloy) has a shear modulus of 41400 MPa whereas steel is 793000 Mpa. Steel is thus twenty times stronger.

DOT Fluid is not oil and oil is not DOT fluid. Don't get the two confused. The OP said oil. Further, we know he's talking oil 'cause he was complaining about the price. DOT fluid is dirt cheap - about R20 for 500ml. Mineral oil is ten times that.

Poor advice.

I might incriminate myself here but I take photos of all sorts of weird cross-sections, failed rims etc etc. I use them in my courses to show people. Unless you've cross-sectioned a nipple, people don't understand the concept of thread engagement and blank bore. It is bloody difficult to cross-section a nipple. I did that with a tiny cut-off wheel on my Dremel.

No, not in a way that matters. Within nipple brands, a 12mm and 16mm nipple will have exactly the same thread engagement, meaning that a longer nipple should never be used as a substitute for a too-short spoke. The extra length comes from the extra piece of non-threaded bore at the entrance point of the nipple. This is just to give you better reach for tool grip with very thick rims. The standard is 12mm but every now and then we have to use a longer nipple as the application requires.

It doesn't matter. The thread engagement is still the same. The weight weenies will prefer the shorter ones but often, depending on the type of rim, we have to use long ones so that they protrude far enough out the rim for a spanner to grip. Long nipples are also prone to breaking off when tensioning the wheel. But for your purposes, it doesn't matter. It is called ANT - Asymmetric Nipple Technology

I also use alcohol when I clean brakes. Sometimes I even put some on the brakes.

I have a large frame in stock.

Aaag no! Not again

How could I forget the sourdough bread? I've never had the chocolate, nor even heard of it. And to think I used to go to SF often. @OP - you can hire an el-cheapo bike and go over the bridge. On the other side of the bay is Marin County - famous for....Marin bikes. Edit: If you are that way inclined, it is also a good place to look for boyfriends.

Ja, it is not the plastic bush we're concerned with, but the soft black rubber seal that seats against that plastic bush. Ostensibly, if there are chlorine or other rubber-swelling compounds in the oil, it swells the seal and makes it sticky. Typically Q-20 would do that. However, once that is taken care of, I can't see what Mavic in on about. I have quite a few dozen customers with those wheels are they seem to suffer no ill effect from synthetic or mineral oil. Oil away, I say.

Take an extra suitcase and get: 1) Lots of coffee beans. The place is full of roasteries. 2) Craft beer. Look for Red Hook EBS. 3) A monster tattoo. 4) A collection of bicycle bells. The shops there have great ones. I'll even take a few off you. I'm after replacing my old flating eyeball bell. 5) Some funky jeans 6) Lots of Peace-sign T-shirts. 7) A bus trip to Yellowstone National Park where you can see people climbing up El-capitan. Take binocs. 8) Pearl Izumi bicycle clothing.

Most oils work in there. And if it doesn't, simply wash off and try something else.

Linseed oil is just another form of threadlock - organic threadlock if you want. The linseed oil has to be boiled so that it becomes varnish. Nevertheless, threadlock is not the solution. Tension is. On an Aksium wheel it is pretty easy to ensure there is no residual twist in the spokes since they are bladed and twist can be seen. Aksiums are pretty reliable, so once it is done properly, you won't have anymore problems. On any wheel with less than 32 spokes and a heavy rider, there is a risk of spokes coming loose and sufficient tension is required, often beyond what the manufacturer specs.

You need lots of spoke tension in those wheels. Spokes come loose from lack of tension and residual spoke twist. Find a good wheelbuilder.

Read your post again and edit the unreadable bits. R1500-00 is a fair price if tyres were included. Tubeless conversions are one thing that we hate here in our workshop. You could spend 3 minutes or three hours getting it right. The choice of suitable valves are limited. Further, they retail for R100-00 and more, each! Stan's tape is one of the few weapons we have for the job and it is an imperfect technology. The tape is hard, has to be stretched and is fond of lifting. It is a bitch of a job and I'm afraid someone has to pay for it. Probably the customer.

Naah, not tautology. The words have two different meanings. I interpret it as "insulting attack" and in the context of the sentence, that's what he (Andrew I think) meant. It may be pretentious but the tone on The Hub is usually so below average that raising the IQ every now and then is not a bad thing.

Typical Cape Town. Yours is stolen.

I fully agree. The absolute number is irrelevant, as long as you have a consistent reading and you'll get that from a few of these systems. It is like a bathroom scale - the number is irrelevant but the deviation from the norm is what you want to know.
