USER MANUAL
AM.170
116.UM.A

WELCOME
Welcome to the Atherton Bikes Family! In 2006 we started Atherton Racing so that we
could push boundaries; from building tracks to producing edits or events it’s all been
about doing things our own way. In 2019, our dream of creating a product range that
pushed bike development as hard as we were pushing our riding became irresistible
and Atherton Bikes was born!
In keeping with this approach, Atherton Bikes are Built Different. All our bikes use
world-beating technology and are handmade in Machynlleth, Wales to bring you
unrivalled fit, strength and performance. Our entire careers we’ve done things
differently so when it comes to building bikes it’s only natural that we wouldn’t settle for
anything less.
We believe that the right bike for you can transform your riding experience and we’re
proud to put our name on every bike that leaves our factory.
Dan, Gee & Rach.
The AM.170
Inspired by Dan Atherton’s riding in the Dyfi. The AM.170 is super-playful and
designed to excel on the steeps.
This hard-hitting, big-mountain enduro bike has a mixed-wheel configuration, DW6
suspension platform with 170mm of rear travel and a straight-through seat-tube all of
which combine to create an awesome all-rounder that is a big hitter in the bike park
and a beast out on the trails.

ASSEMBLY INSTRUCTIONS
When you receive your new Atherton Bike there are just a few simple
steps to getting your bike out of its box and out on to the trails.
To make sure all your components are working perfectly, every
Atherton Bike is assembled and checked by our team of expert
mechanics before being sent to you.
To make sure that your new ride is secure in transit, we then remove
some components, the wheels, handlebar, and forks and pack them
securely in the box.
Assembling your bike couldn’t be easier with our step-by-step
assembly instruction guide. If you need any extra assistance, please
don’t hesitate to get in touch with one of the team, we’d be more than
happy to help.
Grab your tools, make a brew, and get building!
15 USER MANUAL AM.170

FROM BOX TO BIKE
16 USER MANUAL AM.170
Install the forks into the headset, attaching the
stem to the steerer tube. Preload the top cap
and tighten the clamp bolts (ensuring that the
stem is aligned correctly).
Inflate the tyres (as per manufacturer
recommendations) and install the wheels onto
the bike. Ensure the axles are torqued as per
the provided values.
Fit the pedals of your choosing.The non-
driveside pedal has a left-hand thread, so take
care to install these correctly.
Set the saddle height, feeding the dropper post
cable through the headtube port. Ensure that
the minimum insertion mark is no longer visible
whilst maintaining 25mm (min) clearance to the
tyre at bottom out.
Fasten the controls to the handle bars,
positioning as desired. Using a T25 torx key,
attach the brake rotors to the hubs.
Progressively tighten the bolts in a star
sequence until torqued to 6.2Nm.
Fasten the dérailleur to the hanger, ensuring
that the B-tension is seated correctly.
Reconnect the chain using the provided power
link. The chain is already cut to size and gears
indexed.
Step 1: Fork and handlebars
Step 4: Wheels
Step 2: Brakes and Controls
Step 5: Pedals
Step 3: Derailleur & Chain
Step 6: Saddle Height

SUSPENSION SETUP
Fork and rear shock suspension set up is essential to getting the most
out of your Atherton Bikes DW6 suspension system.
Learn how to set sag, air spring pressure, compression adjustments,
rebound adjust, additional tuning options and more in the tuning guides
below.
The recommended settings in the tuning guides attached are designed
to be a starting point so that you can get out on your first ride as soon
as possible! If you would like further assistance tuning your suspension
to get the most out of your bike, please drop us an email, we’d love to
help.

PART COMPATIBILITY
PARTS WE RECOMMEND
We work closely with a range of brands to design and spec’ our builds. We love
these products and guarantee that they will work flawlessly on your Atherton bike.
Whilst our bikes are designed to work alongside the majority of components, some
parts may not fit, for example those that occupy a larger envelop than most (see
the below limitations). Regarless of the parts in question, test fits must be carried
out prior to use, to ensure sufficient clearnace and proper function is achieved.
19 USER MANUAL AM.170
COMPONENT LIMITATIONS
Cranks - Max length = 170mm
Tyres - Max width = *2.5” (*measured width, dictated by tyre & rim combination)
Chainring - Max 36T
Brake Rotor (Rear) - Max diameter = 203mm
- Max thickness including rivets = 2.3mm
Bottom Bracket - Max bottom bracket outer diameter = 49mm, allowing clearance for standard SRAM, Shimano, FSA and Hope models (among
others). Some larger models are compatible, however, this is dependant on the specific form of the part.
Chain Guide - Compatible chain guides include: MRP 1x and Amg, E-thirteen TRS Range, One-Up & Hope (full range) and similar models from
other brands.
Transmission - SRAM UDH: T-Type compatible.
STILL UNSURE?

than happy to answer any questions that you might have.

TESTING AND STANDARDS
Before we launch any new bike to the public we subject it to the
most rigorous testing imaginable at EFBE in Germany, the world’s
leading laboratory for mechanical tests on bikes. Now that were a
little further on our journey we tend to send a new frame but we think
that there is an extra measure of reassurance in the fact that we sent
our first bike to be tested (the AM.200) not as a new frame but after it
had been thrashed by Dan Atherton in the Dyfi for six long months! It
passed with flying colours.
EFBE’s TRI-TEST® goes way beyond established international
standards and reflects the specific challenges faced by modern
bikes. All of our bikes, from the AM.130 upwards have passed the
most rigorous tests of both category 4 and category 5, which means
that even our trail bike is tough enough for downhill rides with
extreme jumps and drops at speeds exceeding 40 km/h
The TRI-TEST® includes fatigue tests, maximum load tests and
overload tests to provide a simulation of the stresses experienced
throughout a bike’s entire life.
