What kind of riding are you doing?
The worst kind street park and dirt. all three never had an issue I even did tire slides with them. they still held up. I weigh 230 too. My mk2 intence however blew up mid air and my maxxis dth tore open one day on a tire slide.

I always hear mixed reviews about mk2's, more bad than good. I usually stick to dirt, occasionally
a little street and park. But a case hard, really hard on dirt a lot.

Can someone explain cranks to me? I know all about MTB cranks but havent a clue with BMX cranks, what osrt of bb do you need? how do they fit together? what are there advantages?

Also, if you use an MTB crank with an 18T cog at the back, what would you suggest is a good chainring size for general pissing around (not jumps but not trials Razz )

BMX cranks are either 2 or 3 pieces. 2 crank arms and a spindle, or the non drive side crank arm and the spindle are one. They use a euro BB like one of these

http://www.chainreactioncycles.com/Models.aspx?ModelID=60289

They fit through a bottom bracket which has a hole through it the size of the spindle and bearings do their thing. The advantages to BMX cranks is they're f*cking tough and they look clean. Also easily serviced.

My advice would be to buy a smaller rear cog because you would need a 40t front sprocket for a reasonable ratio with an 18t rear.

34-15, 32-14, 30-13 are all reasonable ratios.
Could i take apart a cassette and use one of the cogs from that?


i tried, if your chain line is even the slightest bit off your chain hops of under load...


go to your lbs and buy a cog, its like 5$
