The second row is used for after you have put the pin back into the chain and the link is still a bit stiff. rather than bending the chain like you did, you would put it into the forbidden slot t and turn the handle very very slightly so open up the link very slightly. Very good video, bike mechanics is very therapeutic to do and watch 🙏
The second row is to loosen a tight link! you know when you said "When its stiff, you bend it" @ 5:34 . the action of the tool using that part is that the "prongs" push just one side of the link (from the inside out). It uses half the pressure due to only one end of the pin is being pushed into the link. With BMX or just Bikes in general you are perfectly fine with loosening a stiff chain by "tweaking it with your bend method". If there is a safety standard then you need to use the tool and must be within specs.
I've figured out the extra ribs on the chain breaker, don't know how to explain it. flip over the chain after joining and slight pressure on the pin does Phu's last step without bending the chain
Phu I want you to explain in your next video the GT fold down fork and frame stands and also the pegs, in the '80s the bicycle store owner I live close to said that he doesn't carry pegs because they would bend your axles and strip your threads, is this true or is it superstition? Same with the GT Fork stands do they also bend your forks ? 🤔, now I got another question but please explain this one first
When I used to ride a Subrosa Sono when I weighed 260. I used to break the chains often just from the weight. I’m older and I now weigh 320 and I’m 5’11. I’m looking to get a new bike. Right now I’m looking at some of the Stolen brand bikes made out of chromoly. With double walled tires of course. Im not sure a 20” bmx bike could take my weight.
chain will eventually wear out and break just like all parts. usually they are replaced before they get to that point since theyre cheap and easy to replace
That's my thought as well, wouldn't it be easier and safer to push the chain pin back in using a big flat surface(a vice) rather than take the risk by using the highly precise chain breaker?
