Hardening your rear cassette increase life expectancy??

[orsum]

My wax is made from Carnauba wax, Bees wax and Montan wax it has thinning agent’s carrier oils and some other stuff that I will keep to myself. I only use pure wax.

 

Others (Google for the name) add to what I make buy adding ingredients that are not necessary like fillers plus some use a bit of titanium dioxide for colour, a bit of oil to give it a nice smell and the one and only special hidden ingredient they add worth R19K.

 

Guys back to the cassette I will be able to find out what they are made from myself by testing etc but it takes time and money.

 

If somebody has the info all I am ask is for it to be shared.

 

Unfortunately I can see that this subject is causing negative issues which is not what I am about.

 

I was recently told that I had developed type 2 diabetes and had a 20.9 blood sugar level as well as suffering from hyper tension, high blood pressure 195 over 95, extra high cholesterol and I was 46 kg over weight and that unless I change my ways I will be dead in six month.

 

Since that day I lost 26kg, dropped my blood pressure to 125/80, cholesterol back in normal range and my blood sugar is hovering around the 6.3 mark. I also stopped drinking Captain Morgan actually I stopped all drinking.

 

The doctor also thought I was mad when I said I am going to start MTB riding at 59, I turned 59 in August this year. In order to achieve this I started training on an indoor bike until I found the right bike for me, I found it just last week and I will start riding it in the next three weeks.

 

So can I make a longer lasting cassette by making it harder I don’t know. Unless I try I will never know what I am capable of.

 

So if anybody can point me in the right direction and help me find what they are made from then great.

 

If I fall flat on my face then I get up and ride onto the next challenge

 

Sorry for going off track rant over.

Didn't mean to belittle anyone. Unfortunately I do not know from what background you come and thus made a honest mistake.

No probs woz just funni that we kan hide our edookashon on the hub and appear kwite fik sometymes....apparently :-)

 

Anyway JB has appeared and given some great advice so everyone's sorted.

[orsum]

Good Morning,

 

JB mentioned case hardening. I think what you are pointing towards is the base material being mild steel!!

 

I will be speaking to a friend I have dealt with for several years fom Craftgears to see if he can help.

 

Lets see were he takes me.

Just some info regarding possible steels used for the manufacture of Cassettes.

Bohler Steel who deal in specialist tool steels (Alloyed Steels) for the press tool and Injection moulding industry, have an assortment of steel which I think is likely to be used for gears on bicycles.

K340 (Good wear resistance and moderate toughness)

K490 (Good wear resistance and good toughness)

There are others, but these 2 seem to fit the requirements.

 

Just getting back to using an existing cassette and re-hardening that. You will more than likely end up warping the individual blades in the hardening and annealing process. Its pretty unlikely that the blades will come out 100% flat and round.

But why speculate if you're not sure?

Someone is asking for a definitive and you are giving your opinion?

Why not just tell the guy to google it rather than look like some wannabe metallurgist?

Even sarcasm seems to be misunderstood nowadays. I should not have held such a straight face.

 

Awesome, what I should have said is "forget it." There is such a term as "mature technology". Without dismissing any progress whatsoever, this usually means that the technology has been around for many, many years (in this case, the bicycle chain and sprocket was invented by the bicycle industry for the bicycle industry, more than 100 years ago) and many players have thought long and hard about the issues.

 

Mature technology isn't the end of the road. Some disrupter will come along and move it onto a new and rapid growing path. Think CRT TV screens and now light, flat-screen TVs. Think about the leap in developments in cellphones with the advent of smartphones etc etc.

 

I suspect the disrupter for the chain and sprocket will come from belt drive and internally-geared hubs. The growth of mountain biking is a big driver that will force a solution through. The problem of course being not cassette longevity so much but maintenance of the externally-oiled, open cassette.

 

Back to hardening. Cassettes are not produced by a single dominant player in the market that holds us ransom with inferior products. What's available is the best technology that you and I can afford. Joe Low summed this situation up very well.

 

However, I do have some advice for you. Follow the LCHF Version 2.0 thread to improve your health and supplement the advice there by riding your existing cassettes. The LCHF movement is now in the early adopter phase and I think it is cutting edge. Much more will be seen about that in due course.

 

Also, there is some good chain and cassette maintenance advice on here as well, this will help you get the most out of your imperfect but current drivetrain.

I am not some wannabe metallurgist, I am a tool maker who uses these kind of steels every day.

I simply offered some possible options.

I also did not Google the information, I have a fair knowledge of steels and was simply offering it. Use it, dont use it, Your choice.

[Johan Bornman]

If anyone thinks today's sprockets are soft, just try drilling through one.

[Falco]

Maybe put some of that 20k wax on the cassette.

 

If it's good enough to protect an Audi, it should do a fine job on the cassette as well

[goya-goya]

@orsum take whatever anyone says here with a heap-full of salt!

 

I say "go for it" - also... take with a heap-full of salt!

 

Don't let this haunt you.

 

Do your due diligence... Spend some money... invest some time... and yipeeeee! you would have had some fun and you would feel like a pioneer

 

At worst: you would wasted some time, gained some experience, lost a few bucks.

 

!!!GO LANCE GO!!! :clap:

 

sigh... how I miss the old days

Just ignore the grumpy sod

[orsum]

I have been on Google even at my ripe old age I can still find it !!!

 

Wax on the cassette I like that, dry lubrication mmmmmmm don’t think I would do that. But to stop rust !!! That’s another thread.

 

Guys I agree that it may not be one of my best ideas and that the gears will most likely bend.

 

JB you make some great point thanks for the LCHF

 

So I will have a chat to my friend this week but it looks like I may have to just drop hardening my cassettes for now

Just had a very nice chat to a very good friend he is coming to see me today.

 

I will be buying a new cassette for a trial.

 

Details will follow when I have them.

I wouldnt go the hardening route, the cassettes these days are *&^* hard by engineering standards. My only feasable solution would be coatings.

 

Look at a titanium coating or a cobalt coating. Value for money and bang for the buck.

 

a simple comparison is a drill, a normall HSS drill, will drill 3 holes in a 304 SS, a nickel plated drill 18 holes, a ti coat 55 holes, cobalt coat 70 holes. translated that into kms. you will have a significant improvement in cassette life.
