Hiya fellas
Anyone ever heard of an External Bottom Bracket?
I've been told that's what my bike has and that it needs replacing.
Is this a separate bottom bracket type to cup & cone or sealed cartridge or is it simply another way of saying one of those two?
Cheers very kindly
Si

Spindle = Axle - the bit that the crank attaches to.
Spline.= Serrations on the spindle - the crank may / should have matching "teeth" that clamps on the splines.

There are slight variations depending on the type of manufacture.

I reckon I'm going to replace my bottom bracket in the very near future.
I watched some youtube videos about replacement of external bottom brackets, in particular, Truvativ Giga X Pipe like mine and the cranks. It seems like probably the most simple BB set up I've seen so far. All you need to is loosen the cranks with an 8mm allen key, remove them, unscrew the BB cups with a BB tool, take it all out, clean, grease etc & put the new stuff on with a torque wrench. Simple really!
I have a question though, there isn't a great deal of choice when it comes to external BB replacements. I'll probably stick with SRAM, so my choices are either a standard GXP cup set, a Team cup set, or the ceramic version which is about £100 more than both of them! Is it worth going for the ceramic set? How much of a difference will it make?
Cheers
Si
