Thanks so much for choosing MΔSON CYCLES, we realise it’s a big
commitment to spend out on a new bicycle or frameset and we really, really
appreciate the fact that you have chosen one of ours.
We have worked hard to create something special and unique with our first bicycles. Much of the energy and
creative drive behind MΔSON has come from riders and early adopters of the brand like yourself.
If you’ve followed Mason Cycles from the first spark of an idea to where we are now, your encouragement,
enthusiasm and positivity towards the brand and first products have driven us forward from the word go.
Every detail of your new frameset and bike has been thought about, obsessed over actually. The geometry,
cable runs, exact positioning of the stops and ports, the tubing selection, finish, decal design, headbadge...
Everything is there for a reason with the goal being a properly designed bicycle that will inspire you, adapt
with you and carry you on many years of adventures.
Before you read any further, take a minute to write down your frame’s serial number. If you should
ever experience a problem with it, the serial number will help us get things sorted, and if your bike is
ever stolen the serial number is undeniable proof that it’s yours. Your frame’s individual serial number is
located on the underside of the bottom bracket.
You can also register your frame or bike directly online on our website. Click the ‘Warranty’ button on the
top bar of www.masoncycles.cc and fill in all the details.

ASSEMBLING YOUR BIKE
Please take the time to quickly give your bike and
frameset a once over before you assemble them, just
to check they haven’t been damaged in transit. To
ensure you don’t encounter any problems in the future
please read some of the following information in
this guide.
Fitting wheels (A) Ensure the quick releases are tight
on both wheels before riding. Inflate tyres to desired
pressure, 6.2 bar is a good starting point.
Bars and stem (B) Rotate the handlebars upwards into
a comfortable position and secure the 4 stem cap bolts
to 4Nm, working from top left to bottom right, top
right to bottom left. Next, align the stem in parallel
with the front wheel and top tube. Tighten stem
bolts to 4Nm.
Seat post (C) Insert seat post. We recommend
applying a light coating of a carbon-fibre grip paste to
the seat post. Set saddle to desired height, or a good
starting point is to have the saddle at hip level when
standing alongside your bike. Torque the seat clamp
to 5Nm.
MΔSON 3D printed brackets (D) To be used when
attaching mudguards to the forks. Ensure all screws are
tightened securely.

FRAME ASSEMBLY GUIDANCE
Fitting headset (A & B) Grease headset cups. Fit crown race and
lower (larger) bearing to fork steerer. Insert fork into head tube and
fit remaining headset parts in order as shown on 04 Resolution/
Definition Frame Contents. Ensure that you fit the thin metal
headset shims to achieve (C) correct gap. The headset top cap
should not contact the head tube.
Fitting steerer expander bung (D) After cutting steerer to desired
length, ensure steerer is clean and free of swarf. Lightly grease the
internal wedge of the expander, and insert into fork steerer. Torque to
no more than 3Nm.
Tighten the top-cap to adjust headset bearing play.
• Grease all MultiPort insert parts and screws before assembly.
Make sure screws are threaded in carefully and not overtightened.
• Grease headset seats and BB threads before assembly.
• Use the supplied MΔSON structural nylon BB cable stop
when running a mechanical front-mech, remove when using
electronic shifting.
• Use the supplied cable liner to run the front mech cable from
BB cable-stop to mech.
• If you are fitting mudguards, use the MΔSON 3D printed
brackets. These will be supplied with every frameset and are in
production now. Please contact us and we’ll post a set out.

BASIC CARE & MAINTENANCE
Please use an appropriate cleaning product to give
your bike a good clean regularly. This is to ensure that
your bike maintains its proper function and exceptional
looks for as long as possible.
Also if you really love your bike, use a bit of glossy
polish and then wax on your frame every now and
again, this will keep the paint well protected from nasty
road salt and grime.
