Does my sprocket need changing?
so... ive got my back wheel off to get my puncture repaired....
jus cleaning everything up and i notice my sprocket is quite worn. im not sure how worn sprockets get before they need replacing.... is there any rule? i jus thought whilst my wheel is off.... i should do it. heres a pic (click to enlarge)... any comments appreciated. thanks http://memimage.cardomain.net/member...7_30_thumb.jpg |
That certainly looks well on it's way.
How many miles have they done? You probably shouldn't replace just the sprocket. If you're going to do any you should do both sprockets and the chain at the same time. |

Years ago we used to just turn the sprockets around so the tips bent back again. Although I would not recommend this (Just some of the stories about broken chains) :shock: |
Definately replace it. Some of the teeth aren't so bad, some are way hooked. It's practically dead. And the chain will be worn to match.

Just as a note the front sprocket will be three times more worn than the rear.
Rule of thumb, if you can see the wear on the rear the whole lot needs changing. Don't try saving a few bob on sprockets or chain only, it's just not worth it. Cheers Mark. |
okay.
cheers guys! that wasnt a good pic.... i think it is worse than the pic shows :shock: so, im convinved that safety is key here........ but a chain kit??? thats gonna be best part of £100 yeah??? plus a de-linker i guess??? anybody got any cost efficient ways of doing this??? i.e... a nice link to a cheap (but GOOD!) chain kit.... and a chain tool??? :wink: how about this????- http://www.mandp.co.uk/productInfo.aspx?catRef=548446 seems cheap? cheers guys. :D (£££££££££££££££££££££££££££££££££££ :( ) |
You could always get a 47 tooth sprocket for the rear (stay standard 15 on the front,) for some added acceleration & fun :twisted:

Now I'm well aware that the general rule of thumb is to change c/s all together. But, although the sprockets are starting to look worn, my chain hasnt needed adjusting in thousands of miles. So, do I really need to change it?

So with VAT and delivery that works out about £73 for an unknown chain and sprocket kit. Personally I would use vyxxn if you need to buy online as for an extra £2 you get a triple SSS chain and JT Sprockets |
