Helo all,
I have a 5-year-old bike with a Truvativ Firex crankset. The left arm has been a bit loose for too long now and needs replacing. It's square tapered and the crank arm 'square' is almost a circle due to a lot of riding.
I've searched all over the internet for one, and the only two options i have are
Truvativ Firex Crank Arm, in either GXP or ISIS.
I've researched the meaning of these but still can't quite figure out wether or not either on will fit onto my square tapered fixing. Are GXP and ISIS alternatives to a square tapered? Is my square-tapered truvativ firex crank set out of date (thus, will I need to replace my whold BB, etc)?
I would be eternaly gratful to anyone who can make sense of this for me.
cheers
p.s.- in short I'm looking for a left crank arm to directly replace my old one, and it's doing my nut trying to find one, please help
