if i replace the rear sprocket with an aluminum one, do i have to change the chain at the same time?
It usually is a good idea to swap for a new chain, especially if there's lots of hours / miles on the chain.
But seriously, DON'T GET AN ALUMINUM SPROCKET. Alloy body and steel teeth, yea, but aluminum just isn't made for what a sprocket does, even the harder alloys, like 2024 and 7075. I've made race car parts for years, and I've worked with aluminum alloys extensively. Aluminum and metal/metal contact parts just don't generally go well together.
If you do, make sure that your alignment is as close to perfection as Jesus himself would do it, and keep your chain very well oiled.
stock rear sprocket on my bike is alu
yea i've never had a problem with them.
Should do it all at the same time
You guys with alloy sprockets: two questions.
1) do you keep your chain very well oiled?
2) are the sprocket teeth aluminum, or is it 2-piece (with a steel tooth ring and aluminum center)?
1) not really
2) teeth are alu
1: yup. every 5th ride or so?
2. all alum.
so how many miles does the chain have on it? and if your going up teeth on the sprocket you will almost def need to well it would be a good idea at least
Replace them all at once: chain and front and rear sprocket.
