Singlespeed & Fixed Gear "I still feel that variable gears are only for people over forty-five. Isn't it better to triumph by the strength of your muscles than by the artifice of a derailer? We are getting soft...As for me, give me a fixed gear!"-- Henri Desgrange (31 January 1865 - 16 August 1940)

Do I NEED the plastic spindle guard for my sugino 75 bb??

Do I need it? I figure as long as I make sure I regularly service it there should be no problem... what do you think?

Not needed, but makes the bike look complete.

It keeps the bearings on the races and doesn't let them fall in to the center of the bb shell. I think?

it will keep any crap falling into the bearings from inside the frame it kinda provides a sealed environment for your BB

you could leave it out but it would ultimately be foolish.... and pointless

This thread has more dumb answers than usual for BF - good job guys.
OP - it's really only needed if you have a drainage hole or cutout on the BB shell; the idea is that water that gets in through the bottom will hit the sleeve and drain out again without coming in contact with the grease and bearings and all that. So, not necessary but definitely handy if you ride on the street, in the rain, and have a drilled shell.
It's pretty easy to insert by hand, and remove with a needle-nose plier if needed.
