Bottom bracket replacement noob

[DragonNate]

All sorts- from Amazon and Rose Bikes, whatever worked out cheaper and easier to get hold of. The crankset from Rose was a stroke of good timing.... £13 , shop about if you're not interested in the high level group sets- Tourney/Altus/Alivio. Here's a shopping list:

122mm

Thanks, I've looked on amazon and the options are 68 x 122.5mm is this right or did they miss the point out of it (6.8 x 122.5mm) the others are 6.8 x 12.7 cm/11.8 cm. I appreciate your time.

If it is 122mm wide then just get the 68 x 122.5mm English thread UN55, currently £9.99 at CRC

I say UN55 and not UN54 because the 55 has a metal adjustable cup whereas the 54 only has a plastic one
