Profile crank bearing spacer tube?

[Moose]

Do they make different lengths?

I have 2 pairs of Profile made GT 3pc cranks and the bearing spacer tube on both sets are too short?

yes europe and usa?

[Dingobmxer]

yup they do two lengths BUt are normally too short anyway  
what I do is use the thin spacer washers INSIDE the BB to get the correct length
  DINGO

[harris]

yes  moose ,i have other makes the same problem.some people cut them down also
some bb are narrower than others .so you will find they will be good on some frames and not others.
or space them.

    cut a new tube same dia different lenght ,spacers are only for the drive end to get your chain lazer straight,did you people race bikes?

W@nker.

B/B's are different widths, so spindle tubes may need reducing to suit. Spindle washers may be required if tude is too short. Vernier calipers are useful to measure.

  you talking about? im trying to help , a pece of tube cut at a different length and same diameter will do the job,washers are only for the chainwheel end as for the spline that can be hacksawed too

Or dont use them at all , and be careful when tightening the final arm

I think what Dan-Dare and the others are saying is that it doesn't matter whether you use the tube on it's own or put a washer in there - the important thing is to ensure that the distance between the bearings has no gaps (otherwise the crank arms pinch on bearings and make them tight).

Having said that, if I can find a longer length of tube to cut down, I will  

Thanks gent's

exactly what you get in the box dont meen you have to use all, use your own inicitive or somthing

Solving the problem is not an issue - I just wanted to know why I have two pairs with a tube that's too short?

Too long, that I can understand, but too short is just stoopid 

I've found the answer anyway

and it is?

at least we know the difference between a spacer tube and a Euro/US BB 

  DINGO

[Dingobmxer]

AND I always find the drive side spacer too wide to get a good chainline so use the very thin washers that come with redline cranks, and I pop the bearing seals out and pack the bearings with good quality grease because Profile bearings come with virtually no grease in them 
  DINGO

[Moose]

and it is?

There are two lengths for USA BB 51mm & 53mm.
