New School Flight Help Please

(1/2) > >>

Haro82:

Just got some new school twin pinch flights. I might be being a bit stupid here but what is the blue shim that comes with them for ? I presume it goes over the bb spindle inside the BB but why would you need it ?

Any help appreciated .

Cheers
Andy.



 

 

Moose:
Blue shim? Do you mean the spacer tube? :-\

Haro82:
yes probably. Whats it to space?

Moose:
It's there to stop you 'pinching' the bearings when you tighten the crank arms on. You can do without it, but it depends if you want free-spinning cranks or not.

Haro82:
Ahh, I understand now. It just looked to me that it was a little bit big, so I was thinking that when I put the bottom bracket cups in they might not fit snug on the bottom bracket with the spacer in.

I better put it in then  :daumenhoch:

Cheers for the info, Moose.

Andy
