BB QUESTION

(1/3) > >>

Funkyworm:
Hi,

For my new build i'm looking to fit a 3 pc Sugino GT crank set & I purchased this from the bay from oldschool bmx accessories to do the job. I'm used to fitting the new sealed US type BB for flight cranks etc & these kits always include a spacer , my question is should this type of BB also have a spacer or are they not necessary?
Cheers !

Munnyella:
No, all you need is right there.

it all goes together the same as a one piece crank BB.

You will see the bearing seats on the spindle, that kind of replaces the need for a tube spacer.

Yep, the shoulders on the spindle do the job of a spacer tube.

Awesome, thanks,

I'm guessing looking at the picture that my crank arm with the (spider & chainring) will butt up (what in this picture is the ridge on the left hand side of the spindle)  ? I just need to have this aligned on the right hand (drive side)?

Munnyella:
You won't have any `adjustability' with your set up, it'll either work or it won't. there are different spindle lengths available for different chain alignment.

You'll see what I mean once you chuck it on the bike.

Should be fine though.
