i have a 25 tooth sprocket and i want to go faster but im not sure if to get an 8 tooth driver or a 10 tooth driver

10t for more acceleration. 8t for more top speed. and buying a sprocket would probably be cheaper. 23t for more acceleration and 28t for more top speed

I'm on the vital legit list!

Get a 28t sprocket. It'll be harder to pedal at first but you can go faster over time. Good for high speed riding or if you want to be able to pedal at a higher speed to go faster.

28t sprockets put more strain on the chain though so lube that shit up with Castrol chain lube and keep a slight eye on it. If you really wanted to , you can upgrade to 10/30 ratio. That's pretty fast though haha.

I wouldn't run anything above 28t sprocket if you have a 9t driver , just a heads up. Too much chain stress.

28T, when compared to 25T, puts less stress on the chain. Not only do you have a bigger sprocket, which reduces wear, but the angle your chain makes when wrapping around the driver is smaller. That's assuming you use the same amount of force when pedaling though.

Also, 30/10 is slower than 28/9...

I thought that 28-10 was the same as 25-9?

Bigger sprocket and same size driver puts less stress on the chain.

30-9 is the way to go

If youre determined to get a new hub/driver, 8t. 25/8 is virtually the same as 28/9 however there is much more tension on the chain due to the smaller driver. These gearings make it harder to pedal, easier to accelerate, raise top speed, SLIGHTLY boost engagement, and make backpedaling fakies somewhat slower and more relaxed.

I personally ran 25/8 for a long while and it was by far my favorite, though you must be careful which chains you use because the 8t WILL shred them! I had bad experiences with Shadow/Cult Halflinks and 710/410/510 full links. I ran my 410H on it for over a year and never busted a link so IMO thats the best chain to run on that gearing.

Best way to determine your gear ratio is to divide your sprocket tooth by your driver tooth.

2.8ish is the most common. This includes..
22/8
25/9
28/10
31/11

3.1ish is what a good fraction of riders prefer due to quicker acceleration and higher top speed. Examples for this would be..
25/8
28/9
31/10
34/11

Occasionally some riders go pretty crazy with their gearing and jump up to 3.3ish which has a crazy amount of advantage im acceleration and top speed but is also crazy hard to pedal. These would be..
27/8
30/9
33/10
36/11

Some riders prefer really LOW gear ratios, usually around 2.5. This has really really low acceleration rate and top speed but its SUUPEER easy to pedal which is nice if you ride long distances in a very steep, hilly area. Common gears for this are...
22/9
25/10
28/11
31/12

Just keep in mind, higher gear ratio and lower driver tooth both add a ton of extra tension onto the chain. I would recommend NOT running anything below a 10t or higher than a 3.1 without a heavy duty chain (KMC 410H, 510HX, Odyssey Bluebird, Keychain, Wipperman 1g8, 1r8, Fly Tractor, etc.)
