How Bad is My Rear Sprocket?

[LXnastynotch93]

Should I replace it now, or can I stand to ride on it for a while? It looks like a Vortex aluminum sprocket.

[Kurlon]

I'd replace it, looks like lots of side wear on those teeth?

[smokinjoe]

I always look at these threads with some apprehension. I kinda expect it to be a joke.

Yes, replace that sprocket with one made out of something harder than stale bread. If you are doing a couple sprint races alum is ok but on the street they disappear very fast.

You wont regret a good steel sprocket for durability or safety.

[carsick]

Think about doing it right the first time with a f&r sprocket and chain set, all steel. Costs more but lasts much longer, no more worries.

[nhbubba]

That sprocket does not look worn to me. The 'wear' on the sides looks like grease to me.

[OreoGaborio]

Meh, it's fine till it looks like a southern meth head hooker w/ four teeth.

[nt650hawk]

i've seen worse. you still ahve a few more miles to go.

You would not be correct. What you are mistaking for grease is the chocolate that thing is made out of. That thing is not long for this world.

That one gave me a good laugh.

I know it doesn't look horrible, but knowing Vortex and how its aluminum it's probably going to get bad pretty quickly. Looks like I'll have to order up a kit. I'm leaning towards a full DID kit or a Regina kit.

[jasnmar]

I know nothing about how fast these wear.

Looking at yours, I'd order a complete kit and set it in the garage. Run what you have, for now, keeping and eye. Be ready to swap every thing when needed (which may be soon).

[Jim]

i'd still ride on it.
pick up another sprocket from S&C next time you're at the track

[scubasteveRR]

after looking at the close ups and seeing how much metal is shaved off those teeth, I'd be checking it after ever 25-50 miles of riding.

and I'd change them soon than later, having your chain come off at even 30 MPH could be catastrophic

[nhbubba]

It isn't worn until it looks like this.

[carsick]

I'm imagining the CL ad now, "has a slipper clutch".

[LXnastynotch93]

The dark stuff on the sprocket teeth is just chain lube.

I ordered a Regina kit this morning. Better to be safe than have the chain let go, or a tooth snap.

Go Steel or go home!!!!!

[breakdirt916]

if you have to ask, the answer is no

[Uncle Snake]

I've had great luck with Supersprox.

[LXnastynotch93]

I've had great luck with Supersprox.

If I had the extra dough I would have gone with Supersprox.

Steel

[Danz19899]

ya that thing is getting kinda sketchy. definitely go steel i've been riding next to someone when an aluminum sprocket decided to come apart . . . pretty sketchy

[stoinkythepig]

I am not seeing the wear other people seem to see. Looks like it's in great shape to me. Are the teeth worn on the sides or is that just grime that looks like wear (as I suspect)? Can you lift a link off the very back of it?

It's just grease on the theeth. I can't lift a link off the back it's actually pretty stiff.

I think you have thousands of miles of use left on it. I'm not a fan of aluminum sprockets, but there's no reason to change it until you wear it out. I ran one for 20,000 miles once.
