    build a ss frame with american size bb shell?

    and thus use the much larger bb (used in bmx) such as a Profile Racing set up or something? Anyone done this? Just thinking out loud.

    Would you get a much stronger set up?

    Did you have problems with square-taper cranks? I never have so I'm sticking with that.

    I have a few shells from when I built some 26"

    [wheeled BMX bikes, Profile cranks are cool and the larger bearings for the AmBB makes toughness for sure(and weight) Maybe overkill for singletracking

    I trash the euro BB bearing in a year or less (I have always been hard on BBs for some reason. 2-3 a year). The BMX BB bearings are much bigger and cheaper to replace. The Profile Evolution BB is pretty cool, too.

    The trouble with common sense is it is no longer common

    I was looking at the Evolution when I thought about it. The BMX bearings are huge! I run Euro Profiles now and I've already crapped a bearing within a month (although it was my first install so I'm not blaming anyone) I'm taking it apart this weekend. I firmly believe SS is way harder on BB's. I'm totally not a weight weenie and don't mind the weight. At this point, I'll stick with my Euro Profile for a while and see how it holds up.

    You may wanna check out a Texas Fireman's Cruzer. They are a little shop in Austin, Texas. Frames are made in Cali. Address is http://www.firemansbikes.com/. Kinda heavy but bomb proof with an American style BB. Not to expensive either I might add.
