hi all,
i've got some redline proline cranks but they came with euro bb, i've seen on alans they do a sealed us bb kit for 20mm spindle,
does anyone know if this will fit properly ?
thanks,
rob

I think the redline spindles are 19mm :(
-
not the prolines bill they are larger than 19mm, the flight II's however are a 19mm.

yeah i tried a 19mm from my profiles but they were too small,
but would this fit them ?

or does anybody have details for where i can get redline bb as i'm having no luck on the net,
cheers,

:) I have a Redline Proline crank and B/B in bits next to me and they are 19mm.

:) Checked and my Prolines fit in a DK Chopstix Euro B/B,which I am sure is 19mm.?????

just read up on dk's site and chopstix do have a 19mm spindle, but then so does profile and my profile bb does not fit !!
what size spindle do flights have ?
maybe i need one of those measure thingy's :-\

Both my sets of Flights have different size axles so I'm no help on the measurements however, Aldi do a digital vernier caliper for about £8 :daumenhoch:

I could be wrong here but is the spindle raised after the splines, if so then i would imagine it is a 20mm spindle . :)

prolines are 20mm deffo.....

i think i'm in the same boat.
my set of early 90's flites have a non sealed BB, the problem i have is the chainwheel spacer has an inside diameter smaller than the spindle diameter. so i'm thinking i may have the 20mm spindle.
what i don't know is do all crank arms have the same size splines so all i need to do is get a nice sealed BB and put my cranks on them?
to be honest i'm tired of pulling the flites off and putting the one piece in just to go for a ride :-[

You'd better get on to Redline and let them know...

:D :P ;)
Also, the flight cranks with the floating spindle on a sealed bottom bracket some times came with a very thin top hat washer, I think this reduced the internal size of the bearing from imperial to metric ( or the other way around)... not sure on the dates though ???

That's what one set of mine has, a very thin top hat style washer :daumenhoch:

yep me too on my single pinch non full wrap flights,
I could be wrong here but is the spindle raised after the splines, if so then i would imagine it is a 20mm spindle . :)

Custom riders also do these if the 20 mm is too big, which is nice.

19mm spanner
(http://www.radbmx.co.uk/archive/albums/v255/rombloke/DSCF3190.jpg)
ok the spanner fits over the splines...so i guess they are 19mm.
(http://www.radbmx.co.uk/archive/albums/v255/rombloke/DSCF3191.jpg)
but where the bearing sits the spanner does not fit over.....so i was right
(http://www.radbmx.co.uk/archive/albums/v255/rombloke/DSCF3192.jpg)
redline prolines do take a 20mm bearing....

my twin pinch flghts are the same deal, 19 at the spline then 20 at the bearing point
