this is Katy Compton's Trek boom and you
might not know it yet but this is
definitely one of the most interesting
professional cyclocross bikes in the
professional cyclocross peloton if not
the most interesting
let's take a look starting with the
color of the frame that is miami porsche
blue how cool is that could we go to the
build compton rides on a bond trader
montrose saddle she has monterey
Jabbar's and a bond trader stem and I
think from those parts let's look at the
drivetrain because the drivetrain is
actually seriously very interesting
Compton is riding dura-ace di2 but with
mechanical districts which I think she
may well be the only rider at pro level
in cyclocross doing that we've got your
HDI to brake and shift levers she's got
the spring shifters and the drops which
very useful for cyclocross because the
drops are really a very safe place to be
when you're riding down technical
descents you've got a geraci I do front
Beck the geraci IT riemeck Gerais cranks
with WIC works chain rings so they are
34:44 which they feel is a better gear
ratio for Katy rather than the standard
that we see cross riders on which is
3946 got an 11 through to 28 furious
cassette and we've got Shimano's ice
tech disc brake rotors so they are 140
front and rear pedals are also Shimano
and they are XT so we don't see many
cross riders riding straight Shimano XT
our pedals because often the clearances
are a little tighter on lemon with
cyclocross pedals you want the
clearances to be as good as possible so
Compton has gone for second in range XT
wheels are supplied by a new brand so
they're a new company founded by people
from Reynolds blue wheels and these are
called Knight wheels and they found
actually in early season testing these
form really well absorbs a lot of bumps
very very good for cyclocross tires
again is a change for the 2016 through
to 17 season for Compton these are the
Claremont MX PS so most professional
cyclocross riders stick to brands like
do gassed
FMB or challenge Clement are a
relatively new brand on the scene there
tubulars are tubeless rather than tubed
which means you can run sealant in and
there perhaps a little less susceptible
to punching although tubers are not all
that susceptible in the first place and
the MX peas are a Griffo style tread so
the Griffo tread is really the
intermediate tread that writers will use
in kind of dry to relatively sticky mud
conditions but these are slightly
different because they have a lot more
grip in on the side of the tire which
means that you can probably use them in
even the muddiest of conditions because
you're not going to slide out on off
cambers or slippy corners the tires are
33 millimeters wide which is of course
bang on the UC is upper tire width limit
of 33 millimeters and if you're only
going to have one set of a treaded tires
having the widest that you can have
makes sense because why the tires are
slightly grippier they absorb bumps
better and they actually
counter-intuitively roll faster now I've
really covered the basics of Compton's
bite right now but speaking to mechanics
there's almost a whole nother Pro bike
to do in finishing touches it is
absolutely a bike nerds dream despite
they kept using the phrase the art of
the bike and I think this bike
definitely reflects is one of the rules
on Compton's bike is no zip ties allowed
so the disc brake hoses are attached
with fishing wire that is then tied how
cool is that that is just looks looks
very subtle almost transparent and yet
no zip ties allowed anywhere on the bike
and a quick check there are no zip ties
allowed nearly any part of the frame or
bike where water could possibly get in
which is quite likely given the
conditions and most cyclocross racers
has been sealed up again it's probably
something worth thinking about if you're
building up your cross bike at home as
long as you don't get the cave get it on
the cables or anything like that that
will help you out the butt handlebar
tape is wrapped right to the middle of
the bars
meaning that consum can ride anywhere on
the tops quite comfortably and I've
actually only ever seen that before
on track bikes for guys like Bradley
Wiggins when they're riding the Madison
all of the bearings on the bike have
been replaced with ceramic bearings but
they were saying that when they
previously tried full ceramic bearings
so ceramic bearings and ceramic bearing
races once they get wet the bearings
tend to oxidize and freeze up so these
bearings are sir
bearings in stainless steel races which
they mean and they feel are actually
less susceptible to oxidizing and
locking up should they get wet so
apparently this spins very easily which
it does up at the front on the shifters
you might notice something a bit
different
about the appearance of the shift
paddles and that's because they have got
something called Bund X which is a UV
reactive plastic so you put it on on and
UV light over it for four seconds and it
sets and they've added a few edges just
to the edges of the shift levers which
gives it more grip so if you have really
thick gloves very cold hands you can
shift no matter the conditions something
that we're very used to seeing on many
Pro bikes of bi2 is heat shrink wrap
around the brake cable and the DIY and
Thompson's bike is no different but
Compton was also one of the very first
people to have this on her bike finally
almost my absolute favorite detail on
this bike and it's a very very bike very
thing are the drilled titanium bolts
that the brakes are attached with so
you're already saving weight because
they're titanium bolts and then you save
a little bit more because they're
drilled how cool is that
