okay YouTube I think that's going to work at both bearing cups in and put my spacer on the outside
they're got clearance on cranks on both sides there we can swing over here took the pedal off
of that side but you can see we've got that much clearance there let's go take a look at the other
side so there to go on that side yeah about the same maybe a little more I think it will come in
a bit as I tighten tighten everything down yes I went with the anodized red color because I've
also got the you can see in the cassette I've got the red anodized on the carrier in the middle and
the rest of the cassettes silver so I thought that would look kind of nice get a little touch
of a different color up there see I'll show you what it looks like I'll take it apart here and
we'll show you what all the pieces look like okay there's the spindle sticking out see without the
spacers you get quite a bit of shaft so now I have the crank clearanced out there the light
mill is deeper than it used to be and then to make up the outside of the spline there I need that
little spacer and then you have this piece goes in there and pushes the spacer against the outside
of the crank yeah make some measurements here I just want to make sure everything's being pushed
together properly I'll do do some measurements and check everything out yeah I think that's a
as a handy solution right there just a little spacer 24 millimeter or inner diameter to fit
over the spline and then 28 millimeter outer diameter two millimeter thick walls it's solid
ABS plastic so it should be plenty strong I'll show you the there's the recess that it goes into
there right on right right around the splines yeah let me do some measuring and then we'll figure out
if that's the final part or if I have to make a change to it and we'll put it all together yes
one other part I forgot to mention is this is the tube that goes in between the two bottom bracket
bearing shells and this is the original one that came with my Shimano bottom bracket is what I came
up with on this part it turns out there's a ring that's thicker and then it's got the thinner tube
in the middle you can just cut those free and then it collapses down as short as you want so
I think what I'm going to do is before I put this together I'll just put a little adhesive in there
set it out wide and then when I press it down it'll probably press down to about that point
and that'll fill up the gap in there I think that's all I need to do there yeah so here's
the new spacer that came with the new bottom bracket you can see it's about 57 or over 57
millimeters now I'm running three spacers laughs if I run out about 50 millimeters that should be
the correct spacing because and I think that'll work so I'm just going to glue this up about 50
millimeters and then shove it in there that'll be my new spacer so that's how much I've narrowed the
bottom bracket and see right there that's how wide it used to be and that's how wide it's going to be
okay there we go you tube got the crank all back together I think that's going to work out that's
clearance some chain stays same on its side so down here I checked the clearance or the space
between my spacer and the bearing and I think that came out to be about 23 millimeters and
the width of the crank is about 24 millimeter so that tells me that I'm getting enough I have
enough extra thickness in the spacer to push the crank all the way into the bearing which
I guess is what you have to do yeah that works pretty good so you just need to trim about five
millimeters of the splines out of the inside of the crank pull out your spacers from behind the
bearings and then add a five millimeter spacer on the outside and that can push it in and now I've
got a narrower q factor and if we zoom in there I have the scale set on the other side I think I'm
right at a hundred seventy millimeters that's the what's called the Q factor is the distance
from the outside of one crank to the outside of the other crank I think that's about about all
I'm going to get there can't go any narrower I imagine the road cranks have a straighter side
on them than the mountain bike cranks but I if they're too straight they're going to hit the
chain stays that is probably about as good as I'm going to do and I need the mountain
bike cranks because I need the smallest ring on the triple crank there I think that's about
as good as you're going to do but yeah we'll see how that works I'll give you an update if
there's any noticeable change otherwise I think it'll just do what I expect it to do if you have
any questions about that post up in the comment section below and as always thanks for watching
