Formula is brake fluid, so probably Shimano won't work (mineral oil). Try Avid which is also brake fluid, if the size is the same.

The pinch bolts is only two bolts, they are not touching the chain ring at all. Once the pinch bolts are tightened the allan bolt has served it's purpose. 1.5nm of torque is very low. On the Shimano design you tighten a plastic piece (like your allan bolt) by hand, not supposed to be tight, it doesn't come out. The pinch bolts being tight does contribute to holding the allan bolt tight.

Thanks as BAgearA said, the pinch bolts hold the crank on, the centre bolt is to ensure everything is flush before you tighten pinch bolts. This is the Shimano design, take a look at some videos with Shimano crank problems. There may be some damage now to the crank splines, I have never had good luck fixing the problem once the Shimano crank falls off a few times.

What crankset is this? The torque indicated is very low, it's not this bolt that is holding the crank on. If the crank is being held on by this type of bolt the torque is 40 plus N.m.

I bought a few prescription sunglasses on Aliexpress. They work great. Cost was less than R400 each. I prefer the yellow tint ones. Not sunglasses really, but look sporty.

Lots of information about what happened on this old thread.

I have Deore one, 10 speed. You can have it for R200. This is the one. https://bike.shimano.com/en-EU/product/component/deore-m6000/SL-M6000-R.html

I have done it once last year in about November. It was fine. Wide yellow lines. My son rides it often and lives in Somerset West. I probably wouldn't ride in peak traffic.

For a fast race you need a road bike. I used to battle with 50/11 on one bike, also 53/12 on another in normal races just keeping up. I think you did pretty well to do 42 km in an hour.

Email Protune Solutions in Hilton. See what they say.

Lol. I still have it. Brand new, I'll sell it to you. I think I paid R100 on aliexpress.

Find an engineering shop that sells stainless steel bolts. They look much better.

It's fine. They all come out like this. Clean it and put back. Don't use too much grease.

I used the whatsapp number, they replied in a few hours with a new seeding.

Send an email to these guys https://www.protunebike.co.za . They are in Hilton, KZN. I believe that they may be able to replace single stanchions.

Most of the field are palookas, you'll be fine. Only advice is make sure you bike is in top condition, take a few spares. Nothing sucks like bike trouble when you trying to enjoy your day out.

This is it, I used them on the RC2000 frame, I am sure it is the same thing.

I have two, I'll sell you one. PM me.

I had a mate lengthen a steel steerer tube for me once, did a great job. I am not so sure about Aliminium. I have seen a carbon steerer tube lengthen (one that broke afterwards, unfortunately but no injuries). The Cervelo forks have carbon steerer, with aliminium sleeve, so I suppose if you lengthened your carbon fork steerer and put an aliminium sleeve inside for reinforcement, it would be very strong.

I have an aluminium / steel extender which I bought from Aliexpress and never used (as you describe). It looks pretty solid, but would not use it on an MTB or road bike meant for proper riding. Some things you don't mess with. Not worth the risk. Edit: I bought it to use on a bike that was going to be set up on an indoor trainer.

My son broke his 8000 Ultegra crank a few years back, once it started splitting, did not look very solid inside. It was replaced, no issues.

Aliexpress don't issue invoices either. I print the page with the price etc on it and attach that. This has worked for SA customs.

I used to have many problems with grips, tried the Lizzard Transfix grips, they have the gel pad design. They are pretty cheap too, but hard to find. If you come across them, buy a few sets. I bought 8 sets the last time, gave a few to my mates, but still have some left.
