Does anyone have a good source for cheap quality sprockets and chain rings for track?
I'm running 48 x 16 at the moment which is giving me great accelleration particularly from a standing start - but I'm running out of top end which is resulting in my bouncing a fair bit when I hit top speed. I want to go taller but in small increments.
I have 144 BCD chanring.
Happy for recommendations as its only my 2nd track season and there is no seasoned "Trackie's" in our club to give advice.

Haha 48x16 is tiny thats a small warm up gear. The best thing to do is get yourself a 15 and 14t cog. 48x14 is a good race gear, 92in. which is the norm for most.
This should cost you $50, 25 a cog to start with. If you doing sprinting then youll need to purchase some chainring which start adding up at between 50 & 200 a ring. Enduros normally run same gear all day ever day.
Warm up on 48x16, race on 48x14. Ul see a huge difference

Don't buy upgrades, ride up grades

just keep your eye on ebay there are plenty of 144 chainrings that come up
48 16 is so small! its pretty epic that you raced a whole season on that gear
you probably want to race on a 90 or 92, thats what most people will be using
here is a gear chart to work out what chainrings and cogs you need

...it's not a small gear if you're a junior rider (just incase you are)..... there are gear restrictions for juniors - your club should be able to help you out!

Hi Jack1071,
What type/distance of events are you competing in,
maybe I can help. Do you have other cogs, or chainwheels.
As the others have stated, here, the 47x14 is a great 90.6
(what I regularly used) and the 50x15 for the 90 dead.
But for you now, I would think this way,
Your 48x15 would give you a good stepping stone (86.4)
and would only mean getting a 15x cog, which will come
in handy later. I would leave getting into 92 till a fair bit later,
and there is always the interim 91.8 (51x15)
With a bit more info, about the type of rider you are, your weight and
your strengths, I could go into more details.
Hope that helps,
Cheers,
BrentonO
