My wife has a GT nomad sport 2007 and I need to replace the bottom bracket. Could anyone recommend a replacement as I am getting pretty confused?

The only information I can find is that it needs a "Shimano Cartridge".

I'm used to the hollowtech II type of BB.

Thanks

    Square taper, 122mm axle, UN23 or UN55 to budget would be my suggestion, or a Neco if you are looking to save weight at a sensible price.

    Thanks that really helps. I went for the UN55 which seemed cheap at chainreaction:
