AZSSMUK Roller Chain Breaker Detacher Tool for Size #25#35#41#40#50#60 415H,428H, 520,530 Motorcycle Bicycle Go Kart Chains Replacement

Specialty tools are typically expensive, for the price I was worried. Broke 2 50 roller chains and 2 30 roller chains with ease. The pin didnt break or mushroom like people reviewed. They must not know what they are doing. It does include an extra pin also. Worth the money and will get the job done.

I have a manco dingo go kart and I needed to replace the chain. This worked great and Im pretty sure i can use it many more times

It works. Half decent chain breaker. The tips are soft but thankfully it comes with an extra. I would buy it again. I just think its great. I popped two links on some older 420 chain and mushroomed out the whole tip if of the breaker. I managed to file it down and there is a spare it was just kind of disappointing.

I am using it to break #35 but the pin doesnt go all the way because it is too thick. I can only push the pin about 3/4 of the way and then I have to just hammer it the rest of the way. Maybe this would work better for smaller chains but I cant recommend it for #35.

It couldn’t be any more simple than this, used it on a couple links on a 520 dirtbike chain, no problem so far, we’ll see how long it lasts.

The center pin loses its tip and flattens out easily. Alignment sometimes a hassle

If you are lucky.

I used this to break the chain on the lift system of a vintage camper my wife owns. It worked well but I have only used it once so I cant rate the durability.

Worked great for shortening chain on atv.
