Anyone know what the difference is? I’m looking for a first bmx and im not sure why some have bigger size sprockets.
Bigger sprockets usually come on cheaper bikes, or really old bikes. Functionally, smaller sprockets have more clearance for grinding and dropping in to quarters, they’re also harder to get your pants stuck in. Really small ones, though, (25-9 and 22-8) aren’t as smooth, and put a lot more stress on the chain, which is why racers still use big sprockets.
Pretty much all full sized stock BMX bikes have about the same gear ratio (2.75:1), regardless of the size of the sprocket, since they put a smaller rear sprocket (or driver/freewheel/cog). The standard gearing for stock bikes used to be 44-16 (2.75:1 gear ratio) but it’s been going down 33-12 (2.75:1), 25-9(2.777:1) etc.
BTW, the gear ratio calculated by dividing the number of teeth on the sprocket by the number of teeth on the driver.
For example 44/16 = 11/4 = 2 3/4 = 2.75

Seven Lakes performing their award winning show, Blue Voices.Ok, im looking for a freestyle BMX bike that is on the lighter side, but still has a little weight to it. I am on a budget, so it cant be over $330. I plan to ride this at the skatepark so it has to have good cranks. what would the best brand be?
you might want to cut it at 350$.. look i highly recomend you look at Kink bikes. They are a very good company with good quality products that would fit ur needs. All their bikes have three piece cranks, i wouldnt just worry bout cranks and weight, also look at frame size. depending on how tall and heavy you are 5’11 would be ok with a 2.75 frame, sometimes even bigger. KINK will have the best deal and quality. USE danscomp.com for all your bmx stuff reliable and good prices
