I have an older Pino that I been thinking of changing to a 2X9 or 2X10. I know that I will have to replace the crank and bottom bracket, but I need to have the freewheel for my daughter. So here is where I am confused. In the Hase price list they list the Elita Crank and then a Hase chainring with integrated freewheel. Can I get the Hase chainring and use any other crank or do I also need to get the Elita crank.



Also, has anyone switch to 2X9 or 2X10?



Thanks
