hey Calvin I've been hearing a lot about
dump
what is dumb it's that new spindle
interface and it's a pretty big change
for shrimp one of the world's leading
component manufacturers it sounds like a
worthwhile tech Tuesday topic let's get
into the what and why of dub well we're
gonna have plenty of dub coming up so
let's get our voices back on track
sounds like a logical idea Calvin we'll
do it i'm truman and i'm calvin and
today we're here to talk to you about
Schramm's new dub interface so it's
simply a new spindle to the bearing
interface it's gonna make things easier
everyone eventually but this is going to
go away and they're mountain lion we're
gonna see the 30 millimeter and they're
GXP these gone out of here it's gonna be
dub ruling them all a consolidation
unified standard so what is uh what do
you need to know is this gonna work on
your bike is this gonna work on your
friends bikes whose bikes is this gonna
work on well pretty much everybody but
there are some exceptions as always yep
BB 30 asymmetric as well as the super
boost rear spaced bikes that's right
that buy crowd we're just fine because
we're gonna have that phat 4 & 5 the 170
and 190 spacing spindles for that good
to go in the dump
well let's chat about some tools that we
have that are compatible with dub let's
start with going in Shawn this B BT 79
this is going to be a 12 spline tool
that interfaces with the BSA bottom
bracket from SRAM threaded bottom
bracket settles thread it in and thread
it out
sometimes you gotta press them in we
have a press for that
remember these are basically sideways
headsets so we're going in and out but
coming out on the press fit RT ones with
the RT one use it with a hammer
put it in hammers it right out your back
but we got the bottom bracket in and out
then we got the crank I'm pretty
straightforward but it's a big torque 54
Newton meters that's a lot of torque
that's a great time for a PW 6.2 your 8
millimeter bit dial it up and do it so
it's going to be a preload adjuster ring
on all dub cranks turn this down just
get rid of bearing play not too tight
pinch the lock ring shut using the 2
millimeter hex again not too tight and
coming in the future we are working on
new drifts for faster and easier
installation of the press that bottom
reckons that's going to be a little
further down the trail so the quick
review dub is a new spindle interface
with new bottom brackets that you'll
need to get for your bike and it comes
in a PF 30 DB 30 DB 92 and british
standard threaded bottom brackets notice
that we're not changing the frames that
they're going in inside again that's
where the action
[Music]

the winners for the ts4 giveaway
actually the one who's already been
announced

joining us on this dubs
tech Tuesday watermelon cantaloupe
Shortcake fruitcake it's all going to be
really Shakespeare for us these videos
have been great fun to make but more
importantly for you we hope they've done
you some good now if they have tell your
friends give us a thumbs up better yet
