Hello and Welcome to this How To Video
this is the process that I have already seen on line
through the RJ the Bike Guy extremely good channel
and yes well worth a watch
so this is a process that I have seen and something that I need to do
I have got a couple of wheels here
basically this is my track bike my hack
this set is a 120mm and this one just over 130mm
which is a standard 8, 9, 10 speed rear hub
and I want this to go on to this bicycle frame
no way that it will go on at the minute
the process that I have seen is a cold set
a steel process
all that we are going to be doing is
expanding increasing the distance at the back
It will act like a bit of a spring so will come back to a distance
so I am going to share with you exactly how far I am going to have to take this out
I would say do not try this on aluminium frame its got a good chance of creasing
the titanium is regid very solid
and the carbon is a big no no
so do not try this on carbon
it is a cheap frame, it is my personal hack
it is my personal frame it is a project that I am working on at the minute
so do this at your own risk
do not hold me accountable
for any mistakes in that respect
but I am going to share it with you and show you exactly where we are at
as I say we are going to have to take this further out than what is actually needed
to achieve the distance that we need
so the tools that we are going to be using
just got a standard steel threaded rod here
with a few nuts on there and some washers
what we are going to be doing is putting this between the forks and forcing the forks out
I have got a ruler
also got a tape measure
and I have got a spanner
so they are all the tools that are needed
very cheap process this
I am also going to be showing you a process that I have seen as well for checking the alignment of the bike frame
so hang around for that
and lets get a move on
OK so
as you can see there is the rear wheel at the minute
that is the 120mm wheel that is in there
fits in lovely
OK
and this is the other hub
as you can see it is a lot further out
so that at the minute
is bang on 120
exactly 120 so lets get this in
also what I am going to do is clamp on
to this rod here
just to stop it from turning around basically
so as I am increasing the width here
I am just going to clamp this on to stop the rod from turning around
so that is in there nicely
ok so just goiung to start
just slowly
increasing
this rod here
can see that slowly increasing
in size
so we want to take this out to 130mm
so I am going to start be taking this out to 145mm
I think that it is going to take more from what I have read
it takes slighty more than that
OK 145
so lets take that off then
I think that that has worked slightly
I do not think that that has got the distance that we need
so lets check the distance out as I say we are doing this in slow increments
lets put that down there for a minute
so what have we got there now we have got
it has took that out about
about 3mm
so yes we are going to have to go out
quiet a bit more than 145
but as I say if we do this in slow increments
we have got less chance of over stretching it
Ok lets get this back out again
OK so that is 160 now
Ok so lets take the pressure off these now and remeasure
it is about 2mm short of what we need
so what was that that was 160mm
so we are going to go out to 165mm I think
lets go up to 165mm and that should take it out
but yes looks all good so far
so going to try this up now
WOW!
Ok so that is amazing it now fits like a glove
so we took it out to 165mm to achieve the distance that we needed
so we went from 120 to 165 to achieve 10mm
of distance
that fits like a glove very happy with that
ok as I say just do small increments at a time
what we are going to do now is show you a process to check the alignment of the rear forks
Checking the alignment of the frame
very simple process to do there are expensive tools on the market
so if you are doing this on a regular basis or intend to
then I would recommend on investing in a specific tool to do this
all that we are using is a bit of fishing line
or even a bit of string that is hanging around the house
so it is a very cheap process to do
and we are going to use the straight end of the ruler
that we used before
all that we have done is we have tied the line around the front here
ran it down here and tied it here behind the rear stays
and I have got quite a bit of tension on there now
on this fishing line
and all we are going to do then is measure the distance
between the down tube of the Bicycle frame here
and the line
so I am going to put this on the bike frame itself
OK so I have 29mm on this side
and agin 29mm
so what a success this has been
this frame now is all ready to be sent off and sprayed we are going to have a real fancy job done
so very excited about that
