Replacement bottom bracket

[Iluv2cycle]

Servicing bike canlt seem to find replacement BB UN72 bottom bracket. Is there an alternative I can use

 

[Cycleops]

Can't understand that. UN72 BBs are more common than baked beans in Tesco, even the smallest LBS should have one and online they are ubiquitous.

UN72 haven't been made for donkey's. UN55 is the best Shimano square taper BB now but has a solid axle. Tange Seiki make a lighter one with a hollow axle.
