sprockets

Your front sproket is a 13 tooth. You can get a 14 tooth for more top end speed or a 12 for more low end acceleration.
Dont fall into the trap of just replacing the front sprocket only!
It is a great idea to replace the chain and both sprockets.
If you only replace the front sprocket the old chain could tear it to bits in only a few rides.
The old chain will stretch to accommodate the new front and then not match the rear one. and the process will continue until the chain can stretch no more, then $$$$$ maybe a broken case.
Using a chain which has been stretched more than the above maximum allowance causes the chain to ride up the teeth of the sprocket. This causes damage to the tips of the chainwheels teeth, as the force transmitted by the chain is transmitted entirely through the top of the tooth, rather than the whole tooth. This results in severe wearing of the chainwheel. (Not my words, taken from a screed from "Renthal".)
I have seen it too many times.
Rule of thumb is to never mix and match old chains with new sprockets, and vice versa.
The new chain should have 30mm - 40mm of free play with you sitting on the bike.
You will never be able to correctly adjust an old chain on new sprockets, because as it rotates it will climb the ramps on the sprockets resulting in a never ending tight/loose situation.
