Don't get paraffin on brake pads. I only clean the drive train with paraffin, rinse with water and dry in the sun.

He has done some stuff for me, really good at paint work. Especially reproducing damaged logos on areas of frame. He paints on the logos, does not use decals.

I go into the shop often to fetch stuff I want, I work close-by. Prices are very good, if they don't have something you want, will keep you updated as to when it will arrive, then reserve one for you.

https://www.kreitler.com/wattage-information/ Check out this link, some wattage measurements for different diameter rollers. The Tacx are 3.93 inches in the middle, so you can work out a table for your weight and tire pressure based on this. I have done this for myself and it appears pretty close.

I had this problem with Shealth and Discovery App. Called Discovery call center this morning, the call center said they could see my two workouts in their back end, but it was not reflecting in the points awarded, they did something manual on their side and now my points the last two days reflect on the app. The technician that assisted the call center agent told her there weren't any problems on their side and I should call again and speak about the settings on my Samsung Shealth app if the problem continued. Of course I mentioned that if Discovery can see the missing data in their back end systems, the problem is probably not on my phone.

I made a batch of this wax, it works ok. Like a wet lube. Used it on the mtb, rode through water, it stays on quite well, does pick up a little dirt. Once poured into the small bottle the mixture goes solid, like a very soft wax. If you leave it in a glass of hot water it melts and you can apply it. May want to do this outside as the xylene smells slightly. I used 150 grams candle wax, 200 ml paraffin oil and poured the molten mixture into 6 x 100 ml bottles, each with 35 ml of xylene in, so probably used a little less wax than the recipe suggested.

Try liquid paraffin from Dischem. I am going to try the recipe. I have tried candlewax on its own with mixed results.

Rapide.co.za sell them.

I would worry about spoke tension on a carbon wheel if you skipped a few holes. Uneven tensions would make some spokes break sooner, also too tight and a spoke could pull through the rim when you are riding. Not a catastrophe, but expensive to repair. You can buy Novatex hubs on Aliexpress for less than R1000, repairing the carbon rim is going to cost a lot more than that. Rather don't chance it.

I have heard of the pig testicles stuff. It's called testis compositum. I think it is a homeopathic placebo treatment.

I am a big fan of Hatherly, hope he wins. He would only be allowed to wear the jersey in ebike races, so not too often unfortunately.

I see Kulharvy is riding ebikes world champs tomorrow at Mont-Sainte-Anne. Guess I would also ride an ebike if it was sponsored bike.

Agreed, would never take off XT to put SRAM, just plain wrong. Best surprise ever was when I found out my wife's 11 speed NX derailleur could be swopped for an SLX 11 speed derailleur while still using the SRAM shifter, I said to myself "which genius from Shimano designed this?" NX derailleur did not last a year with no oval chain ring. Spring was so loose it was rubbish.

I am sure the clutch would need servicing anyway after a while, no matter what you use. The mud and dirt from riding is probably a lot more damaging that an oval movement. I am not too worried about my clutch, just learnt from this thread that you can service it, which I will do.

Another reason to use a round chainring. I really like Shimano clutch after battling with a few very muddy rides and getting chain suck.

Long term would be a year, I guess. I haven't really noticed any problems with my setup after 18 months. Just that the clutch is very stiff. Has always been like that. Gear changes are more difficult with the clutch on.

In the youtube video the Shimano clutch derailleur is a bit stiffer than the SRAM, which could be why it is affected more by the oval movement. The extra stiffness may be an advantage or disadvantage, it's why I like Shimano. I use oval and round chainrings, I don't think the chainring shape makes much difference. At the moment I am using oval because it's what I have.

Check this video out. My derailleur moves slightly like the XT in the video. The guy in the video reckons this causes problems with the clutch derailleur in the long term. Guess it is possible to service the Shimano clutch derailleur and this should be done after a year or two.

Doesn't matter where you measure the chainring, if you take from one side to exactly opposite the other side there is the same number of teeth. The chain only contacts about half the teeth in the chainring at any one time. I have a 34 oval chainring and just checked now, the derailleur (SLX 10 speed clutch) does not move much when you pedal.

What derailleur is it? I don't think the oval makes much difference to the derailleur. The total amount of chain in contact with the oval chain ring remains constant as the chain ring is pedalled. So the derailleur should not feel much difference between round and oval.

I like Shimano because the mineral oil has a higher boiling point than brake fluid, mineral oil also doesn't absorb water so you don't have to bleed them as often. I don't think XT is worth the price over SLX, SLX is very good anyway.

They are fake, the real ones have internal nipples on the spokes.

They look original. Do they have one round spoke opposite the valve on each wheel. Look very similar to my older Ultra Boras. A fake won't age very well especially the braking surfaces. Also they would be heavier than originals.

Seems like they busy on Takealot.com, lots of very good deals there for Sidi.
