Chains and Sprockets

Greetings

Any recommendations for purveyors around Sydney for the above? The ER5
is getting somewhat "clicky-clacky" on the take off after a round trip
to Bris-Vegas last month. In fact the chain is more like the spag I made
for dinner the other day.

I'm not fully across the difference with o-ring, x-ring etc so am happy
to accept pointers to good web sites that have good info.

Has anyone an opinion on Esjot (german) sprockets?

According to one site the front is a 17, the rear 42 and they
recommended DID 520 (L106) as the chain.

Happy to order via mail or the inter-thingy if it saves my hard-earned.

The front sprocket does 2-3 times as much work as the rear and wears out
that much faster. A worn sprocket wears out the chain faster than a new
sprocket. When I am replacing chain and sprockets I buy two fronts and
1 rear sprocket and then after say 20k replace the front sprocket.
Should make the chain last longer and get more useful life out of the
rear sprocket as well.

Although not recommended, I'm with Nev on the use of a second front
sprocket where warranted.
A waste if your chain is about cactus. DID, EK, and RK are all
recognised as quality chains.
There are some others less common - google could help there. The X-
ring is the later technology.
It should give longer life but will likely cost more. How long and how
many kms are you after?
If long term isn't an issue go for the cheaper O-ring. Again, plenty
of info about on google.
Re sprockets - depends whats available for the machine and at what
cost; the harder
the metal, the longer the life.
If you intend to do the swap yourself, investigate how to fit a rivet
joining link. If that
troubles you, choose a chain with a clip type joiner making sure that
you put it on the
correct way. If the used chain is connected by a rivet type joiner,
then that can be removed by
grinding the pin ends off the plates with a small angle grinder and
then prising the outer plate
off with a screwdriver if you don't have the correct tool. Some front
sprockets have a rubber
cushioning plate stuck either side. This acts as a sound deadener.
Unlikely to get one of those
unless you buy a more expensive OEM. Don't fret about it, others are
ok.
