So, my bike is an old Nishiki Century, converted to fixed... But Im having trouble keeping the chain tight, any pointers? Im cranking the nuts down pretty tight but it doesnt seem to be workin all that great.

Would it be worth it to put track dropouts on my bike? Ive found them around for not to much but what does it take to actually get them on? a jig? or just some careful measuring?

Last but not least, I might be moving to Phoenix here in the next few months, anyone ride there? Im not familiar with the city at all. how are the LBS and such?

thanks!
