The Chainring can be run on the inside or the outside on the right crank arm, which ever suits your set up the best. We suggest using a YST Sealed Bearing bottom bracket with these cranks for the best adjustment option, you can find these in the bottom bracket section of our store. We have no problems extending that time, but we need to know so that we can stop the unpaid case being automatically opened. You ordered the wrong style.

We're a bunch of 40ish year old BMX enthusiasts & collectors most probably much like yourself, some of us have been building and riding BMX's since back in the early 80's. A couple of years ago with the Old School BMX hobby growing at a rapid rate we noticed there was a distinct lack of replacement parts on the market for Old School BMX's and what was available was way over priced, we decided to start BMX Works to source original and reproduction old school parts so you could all finish of those builds in style without sending you broke.
