the other side is 24mm inside diameter
What replacement bearings do I need ? and where from please - Im struggling
cheers
Do the bearings have a code on the seal on them? If so let me know.
Sounds like you have a GXP crankset. http://wheelsmfg.com/complete-crankset-bb-adapter-guide gives an idea of the many different BBs.
What year is the bike? From google http://www.thebikelist.co.uk/fuji/altamira-cx-1-5-2014 for that model year it was BB86
22/24mm is a GXP bottom bracket, Truvaiv originally.
Yep definitely GXP, BB86 by your shell measurement.
Your options are basically replace with same or one of the conversions such as the Hope PF41 although if you're keeping the existing GXP crank, many of the conversions make less sense.
Alignment is critical to pressfit BBs as most have plastic shells so will happily go in wonky if you try, leading to creaks and short life, as compared to say, an alloy headset cup that will pull itself into true if its slightly out of line on insertion. While whacking s PF in is mechanically simple due to the necessary alignment it's one of the few jobs I'd seriously consider asking my experienced LBS to do for me.
+1 BB86 GXP
Basic Sram ones aren't very good. Better ones exist, like Wheels Mfg. None are that good though, as GXP isn't a good design, particularly in pressfit BBs.
