Hey guys,

Im new to this biking forum but Ive been on many forums before so I used to search button a few times trying to find answers to my question. I also learned a lot of other information that I did not know about.

One of the things I learned is that my murray road bike is a (pos)? I did not know that when I bought it as a complete for 40 dollars. Im kinda bummed now since I fee like I was ripped off. Oh well. Lesson learned!

My intentions of getting the murray road bike was to convert it to a fix-gear. I got some new wheels and a 17t fixed cog with lockring. I got everything installed on the bike and then realized something was odd about the crank.

My crank is a 1pc crank with 2 sets of gears. I dont mind that it has 2 gears but I realized that my crank has this weird play when I try to slow down. I try to apply pressure to slow down and it seems like the crank moves a tad back before I feel the tension in my legs. I tried to replicate it many times and I was successful. I noticed the chain does not move forward or backward like the crank pedals do. I was told to try and tighten the bolt on the outside of the crank, but that didnt do anything.

Do you guys have any suggestions?

I was also looking to replacing my 1pc crank with a 3pc. I read that I might be needing a conversion kit that has fittings for a modern day bottom bracket. Can you guys point me in the right direction to learn about this?

Thanks!
