Since you say you had to replace the square taper cartridge bottom bracket on your old bike after one year, I'll venture to say that you'll probably have better luck with the Octalink bb. I've certainly not had to replace an Octalink bb within a year, and that's using the bike it was on in all sorts of challenging conditons (mud, water, etc).

I gotta say, though, I think you're overthinking this. It should be a good bb. Have fun with the bike.
