yes it is I have one. and i love it. yes it is I have one. and i love it.
yes, 28/9 gearing is very popular with riders. it provides a little more resistance than the even more popular 25/9. theres nothing wrong with that gearing at all.
if you are looking for a 25t sprocket then you need a 9t rear driver other wise it going to feel like you a pedaling forever and not going anywhere there are websites or just look online for proper bmx gearing ratio's also you may need spacers for your cranks
25t means that there is 25 of the little spikey teeth on the outside of the sprocket :]
If the driver/freewheel isn't too badly worn you can keep using it even if you replace the sprocket.
yes it has a 26t sprocket
Yes, and 3 piece cranks.
(2t + 1)(3t + 11)
oh my god, that was the exact homework i had few days ago, but you have to have a calculator to do this. just plug in the numbers in the but ton Y=, one column you put-16t squared plus 25t plus 6 then the next column you put 0. the graph should form a parabola.
Yes Pretty much all 3 piece cranks should fit any sprocket you buy for them.
25T 9T rear driver ive got one orders for x-max its coming in about 70 days :|
i wouldn't say its big but a 22sprocket is the smallest you can get from gtrider
6t2+25+11 = (3t+11)(2t+1) when factored Use the quadratic equation formula.
