The bottom bracket on my Mongoose Thunderball is creaking really badly, and needs to be changed. I've never done this before, and decided to take it to the LBS. The LBS guy gave me a quote for a replacement BB which was in my opinion, a bit expensive. I have decided to look around and buy a replacement by myself (probably on ebay...I've already seen a few which are a good amount cheaper than what I was quoted by the LBS guy). I'm looking at a Truvativ Gigapipe DH BB. My question is if anyone knew the bottom bracket geometry for the Mongoose Thunderball 2005? Is it a 113 or 118mm BB?
