please help me to get the word out about a serous flaw on many china floating brake disc ive tried several brands and they all have super thin cheap steel washers that can rust out in no time , when they must have stainless ! And many of these are being used on hight powerd ebikes , so they are allredy under sized for the speed potentially of the bikes.😢
Why does it spin the wrong way? It clearly is a hope calliper. The point of small and big pistons is that you hit the small first and then the big piston for better heat transfer.
What does this video mean? I don't get it. Does it happend on real bike. If the rider weight 100kg and speed 80kmh above maybe it will be like this IMO.
@@jedunboxing4127 well, the conclusion is wrong. The energy dissipated is the same I assume, but with the floating rotor you have more mass to heat up (the al alloy spider is really conductive) so the rotor heats up less (you can see the outermost diameter, being further from the spider, is glowing more than inside) the pads are dissipating the same amount of energy as before, but with the rotor being not as hot, you wouldn't be as likely to cook your caliper or glaze the pads over, as you would with the solid rotor, this test isn't realistic at all though, since there is so little time, any brake would suffice really, the issue arises with high speed and/ or heavy weight repeated braking, like on a steep mountain descent, but then you have much more airflow than here too, and nobody is using their front brake only. Personally I haven't seen a glowing rotor ever, 300+ degrees (brown oxide layer) sure, but for it to glow you need like 2x times that. I have witnessed heavy braking from 60 km/h by heavy riders and have done so myself also (but I am lightweight)so the opportunity was there, if it were to happen irl.
Fun fact : This video is gonna be on your recommendation
yes
You did it!
Yes but in 2021
I actually looked for it on my own
bruh just today i googled their disc rotors and now its in my recommended already
I didn’t but it still showed up
Great CZcams recommendation!!
Amazing
i was here before the video gone viral
yes
Nah ini baru galfer original
Just read a news about your new 2.0 mm Disc Wave rotors on pinkbike .

After 5 years youtube alogritm decide to show me this...
Depois de descer a serra de bike esbarrar no disco ao colocar a magrela no suporte.... Só vai dar uma queimadura de terceiro grau.😫

What's happening dude?
wait till the music buzzes your ears.

It's about to push the brakes parts to the limit and find his "ceiling"
😳
I love the ear rape music
so floating disc will cook your brake pads and burn it more and non floating disc ,the disc it self will cook together with the brake pads?
How the hell did you come to this conclusion? 🤣
by watching this video..🤣

Sooooo how fast was it? I mean thats kind of what you want to know if you watch it right?
We test the bicycle products between max. speed 70-80km/h
@@galfer_brakes Thanks for the answer
@@galfer_brakes That’s a little excessive isn’t it?
@@Drago0900 there needs to be some kind of safety factor somewhere. Why not make sure the brakes work at Tour de France downhill speeds? :P
@@TinglingTaco well said
see you in another 5 years
what the name of calliper?
Hope V4
thank you@@galfer_brakes
Sadis
rip ears
Well that was some awful music
So nasty audio! Better not to include!
