does anybody recognize this if not we'll give you a little bit closer of a look here this is the bsd
revolution hub this was sent to me directly from grant smith the owner of bsd himself
to which i owe a gigantic thank you and in today's video we are going to be taking apart
the bsd revolution hub and comparing the internals to the free knight planetary free coaster the hub
that this revolution hub was based off of and it looks like the hub guard wants to come off already
so i'm going to be taking apart both of these hubs and comparing their internals and one
thing worth mentioning real quick before we get into this is that there is an updated planetary
free coaster from free night that some overlap occurs with this hub and i will explain as i go
so with that being said let's get this hardware off of here and to not bore you guys with all of
this part of it i'm going to cut directly to the part where we've got all of the hardware
off of here and we're ready to take the driver out as well as the same with the planetary now
all right so we got the hub guards and hardware off of here that we need to in order to take it
apart so we'll take the jam nut off of here and taking the jam nut off of here is where one of
our first differences lie and that is that the jam nuts are different between the free knight
and the bsd and the reason for that is that the bsd jam nut is made to fit their proprietary
drive side hub guard which is included with all bsd revolution hubs it comes with drive side and
non-drive side hub guards so as you can see it fits that perfectly let's set that aside and get
to the part that i feel like a lot of you guys are here for we are ready to take the driver out of
this so all we need to do to take the driver out is literally just pop it off of here and pull it
off and as you can see the clutch came with it let's put that back on there we'll get to
that in a second so we've got the driver here it is very very familiar upon first
impressions here and now we've got the driver from the free knight planetary free coaster and the
bsd revolution in hand the bsd is on the right the free knight is on the left and as you can see here
the bsd has a little bit of extra material around the bearings whereas this one's a little bit
thinner but the paws and springs and everything in here looks exactly the same this is a good
place to point out that the paws and springs pull downward instead of spring upward for how this
hub works if we look at the teeth here we can see that the teeth on the bsd are a little bit
thicker as well this is something that i believe translates over to the updated free night hub
because grant smith told me that the only thing that is completely identical between the two hubs
is the drivers so let's set those aside and take a little bit closer of a look here to our hubs so
the clutch is already partially out of this one so let's take it off and as we can see here we
have an assembly the clutch does not come apart it is all self-contained and there is a c-clip here
that you would use to take it apart if we grab the one from the free knight we
can see that it's a little bit different in that this one once you take the spacer out
it completely comes apart and it's at this point of this clutch being apart that i feel that we
need to take apart this clutch assembly in order to directly compare them already we're seeing
differences in material where we can already see that the clutch assembly from the bsd is made out
of plastic whereas the one from the free knight is made out of a different material keep in mind that
bsd and free knight worked directly together for over two years working on the bsd revolution so
i'm going to take this apart and grant if you're watching this and you didn't want me to do this
i'm sorry but this is for science and the first parts that we're going to compare are the spacer
and the wedge piece which i call the triangle piece and all of my videos about these hubs
and as you can see upon first glance they are very similar there are differences
obviously the material one is plastic one is a different material and then if we take a look here
vertically we can see that the bsd here on the right is much thicker than that of the planetary
assuming because of the c-clip and everything to keep this a self-contained unit
otherwise it is very very familiar now let's grab the planetary gearing systems of both the
bsd and the free knight bsd is on the right free knight is on the left and aside from the material
differences we've already pointed out we can see that one is thicker than the other otherwise they
are very similar and function very similar upon taking a closer look i will say that the material
construction of the bsd does feel very premium in comparison to the free knight i believe that this
is some sort of 3d printed material so naturally a plastic material and makeup is going to feel a
little bit more premium whenever it's a production piece so with that let's take a look at the actual
inside of the hub shell of both of these hubs so the bsd revolution hub as you can see inside here
is internally machined for this clutch assembly to fit directly within the hub
shell so the hub shell is machined on the inside to fit this thing whereas on the free
knight there's actually a piece in here that is to adapt the clutch assembly to the hub
this doesn't function any differently but it does show that this bsd hub is a little bit different
than the free knight now i'm also not sure how the updated planetary free coaster from free night
differs in this respect i do believe that there still is a difference and that the free knight
does still work the same way but i'm not 100 sure what i can say for sure is that the differences
between the planetary clutch assemblies of both the bsd here on the right and the free knight
here on the left are great enough that these small parts and planetary clutch systems are not
cross-compatible with each other between the hubs and what i mean by this is that you cannot take
this planetary clutch system from the bsd that is self-contained and thicker and plop it into a
free night hub and have it just work what you have to do for that is contact free night directly and
get a different spacer that goes into the clutch system and then it can work but i want to make
this clear you need to contact free night directly to do this if you're interested in it and they can
give you more information on that and so i feel that we're starting to see that these hubs aren't
exactly the same between the two of them there are vast similarities and some things could be
cross-compatible with different parts but they are not exactly the same and we can continue
looking at these differences in looking at the axles before we actually take this out which we
are going to take the axle out of both of these let's take a look at the surface as we can see
here on the bsd there is a smaller allen key than we may be used to with the free night hub
when we grab the free night hub here we can see in comparing them that one is smaller than the other
don't mind the little tubing that i put into this axle if you missed it i did a custom axle
mod where i put a tubing in here in hopes of making it stronger but when we look at
it we can see that one bsd on the right is a six millimeter hole and the free knight on the left
is an eight millimeter hole and this is also something that i believe has been updated in
the free knight hub so i think that this one will have a six millimeter hole as well but there are
differences here that might mean that the axles are not cross compatible as well and the only way
to find that out is to take it apart so once again i'm sorry grant if you didn't want me to do this
but i know you've seen my previous videos on the free night where i apologized to tal for very
similar things so let's grab the shout out to park tool hammer and get this axle out of this hub
easy as that it appears to just be an axle but we need to look closer in comparison to see some
differences here so now we've got both axles out of the hubs we've got the bsd on the right
as usual and the free knight on the left and aside from some differences in color we can immediately
see the difference in the hole through the axle that we already talked about as well as if we turn
them on the side we can see a difference in the color where the driver slides on in that in the
bsd it's actually longer than on the free knight and that has to do with that internal machining
that we already talked about inside the bsd where the clutch assembly fits directly within the hub
and the fact that it's thicker it needs to go further into the hub which means that this collar
here is gonna have to be longer than on the free knight and unfortunately this also means that i
can't take my solid titanium axle and put it directly within the revolution hub and i feel
that the last thing we haven't addressed as far as the internals of these hubs go
are the bearings this says six nine zero two rs on the bearing and then the free knight says six
nine zero two rs as well the insides are the same bearings as well same numbers on them
so same size bearings in both hubs and it's at this point that i feel that we've talked about
everything within these hubs and the differences in them so i think in the future there's going to
be some sort of chart or table with overlapping small parts compatibility there will be a way
for you to find out which small parts that you need if you need anything for your hub but with
that being said if you guys have any questions about the hub itself and how it works and how it
rides or anything like that you can refer to my game changing free coaster playlist right here
for all of the videos that i did about the free night planetary free coaster in the
very beginning because functionally they are the same even though there's some small differences
in these small parts inside these hubs if you guys had any comments or questions that weren't
answered in the videos in this game changing free coaster playlist leave them in the comments down
below and hopefully if you're new here you'll hit the subscribe button while you're down there
and i've got to give a gigantic thank you to grant smith and tal of bsd and free night for
giving me the opportunity to make these videos i truly feel that the revolution is upon us and
as i said last year this free night planetary free coaster has the potential to change the
game in free coasters forever as it feels like it's starting to do so thank you guys
all for being here and watching and hopefully we'll see you next time for another one goodbye
