Alright everyone, I have a 2005 Hardrock Sport and after making some observations and plenty of searching on here, I think I need to do something about my bottom bracket. Its been making noise for a while now and it is getting worse. I don't really know much about buying/installing a bb so I wasnt sure if what I found on pricepoint would fit properly. They are showing a Shimano XT UN73 for only $19.98 and from what i read from Specialized and the product info for the new bb, it looks correct. They are both 'square taper' and 68x113mm. If anyone knows if this will work correctly or if you have any suggestions, I'd really appreciate it. Thanks in advance for any and all responses!!
