I ride a GT GTR series 4 with a square taper bottom bracket. I'm looking to upgrade to a external BB. I've called GT and they are saying my BB shell is a BB86, but everything I see about BB86 show press fit, and when I look closely at my BB I can see threads. I'm just looking for some advise on making this conversion somi don't waste time and money ordering incorrect parts.
