Sprockets And Chains

[acton mike]

mu 2016 T100 with 45,000 KM on it has worn out chain and hooked teeth on the sprockets; all of these components are the originals. I have a new chain and new sprockets.
In looking at the replacement sprockets, it appears that they will fit on either way.
So, in what might be the dumbest question ever posed, could I not just turn the original sprockets around so that the new chain would be running on surfaces of the sprockets that are not hooked.

I have the new chain (which I will install) and sprockets and the sprockets were not all that expensive and this is not a case of wanting to pinch pennies but i am genuinely curious. to learn if I can turn the sprockets around. If I can then I will and save the new sprockets for when it is time again to replace the chain and sprockets due to wear

Bad idea.

Bad idea.

I appreciate that it might be a bad idea but I would like to know why it is a bad idea

The worn sprockets may damage the new chain.

not a place to cheep out!!

I get it guys; not a place to cheap out and that it might damage the chain.
I already have new sprockets and chain and the money is not an issue.
I would just like to know if someone can tell me how the chain might be damaged; i like to know the whys and hows of things

Because when you decelerate, the wear takes place on the other side of the tooth. So there is a degree of wear on the other side of the sprocket. So if you turn the sprockets, now when you decelerate, your new chain will be running in the hooked tooth. Good way to destroy a new chain.

The 'hooked' sprocket is worn as well as bent. Reversing won't make the chain fit any better.

I wouldn't mind betting that back in the day when bikes were the cheap staple transport of working people, owners would get the last few miles out of chains and sprockets in any way that they could when money was tight. However, where you could get away with it on a an ancient low powered machine from the 1940s and 50s of fifteen or twenty horsepower or much less, you don't want to be going down that route with a modern bike with modern performance. New chain & sprockets......job done.

thank you

The new chain fits into the new sprockets with no gap. Chains stretch to a small degree over the course of it's life span and the rollers wear which causes the elongated gap between the sprocket teeth. Wear from dirt and debris on the chain contribute to the demise of a chain and sprockets. That's why good chain cleaning and lubing will increase the life span of these components greatly.
If you use a new chain on worn sprockets the stretch will happen sooner and then you have a worn out new chain that fit's your worn out sprockets.

When i was a kid i turned the sprocket around on my bicycle and it worked for a long time but the chain finally broke. It was a low HP machine.

Though this is two months later, in case anybody reads this, the most important reason to have chains and sprockets in fine working order is that it looks good for the bike. One does not want to go about having their Triumph looking shabby. No.

Hooked worn sprockets have a high chance of breaking teeth when reversed , causing damage to new chain & possibly other sinister effects.

Reading about 'stretching' the life of chains led me to work out something I found on an old bike I bought 10 years ago. I purchased an old Matchless single and bought a new drive chain. I noticed the old chain had a cranked link. I couldn't think why when the sprockets were all standard and the new chain was the correct number of link according to specifications with no cranked link. I now realise the most likely reason was as the chain wore a previous owner had cut out a link or two and then needed the cranked link (half a link) to make it fit.

thanks to y'all (is that the correct spelling?) for your input on the chain and sprockets. New chain and sprockets installed and all we need now is warm decent weather and we will set to work wearing out the new sprockets and chain
