R.
WELCOME We are excited to welcome you to the Viathon family. This manual contains important information regarding the safe assembly and use of the Viathon R.1. In this manual you will learn to assemble the bike from start to finish. From receiving it packed in the box to a safe and ready to ride bicycle. The tools required to build it are contained with the box it is shipped in. The proper tools can also be purchased at most bicycle shops and hardware shops, should you need to replace them.
SAFETY WARNING Please ensure that you read and follow the instructions carefully, failure to do so can lead to injury or death. If at any time, while you are working on the bike and aren’t sure what to do, don’t have the appropriate tools, or for any reason are un-equipped to proceed, you can take this bike to the nearest Viathon dealer or local bike shop.

ASSEMBLY SYMBOLS Please inspect the following chart. It depicts the symbols that will be used in this manual and what they mean. Please refer back to this page as needed. The following section will explain how to assemble the bike. These instructions use text and images to explain how to safely and accurately assemble the bike. Please follow these instructions carefully and deliberately. This bike can also be taken to any Viathon dealer or local bike shop to get assembled.

SEAT POST INSTALLATION Before assembling the seat post ,apply carbon fiber assembly gel (such as fiber grip) to the inside surface of the seat tube. Next, insert the seat tube and tighten the seat post clamp to 5 Nm. 10 Make sure the minimum insertion mark is completely inside the Seat tube.
SEAT POST INSTALLATION 5Nm 11
WHEEL INSTALLATION Place the wheel in the fork drop outs. Align the brake rotor between the pads in the brake caliper as a guide to place the wheel fully in the dropouts.
WHEEL INSTALLATION 13
WHEEL INSTALLATION Insert the thru axle through the dropouts from the non-drive side. The skewer goes through the hub then threads into the drive-side dropout. Rotate the skewer and test flipping the lever from the open to closed position periodically. When you start to feel some resistance in the half-way position, move to the full-closed position. If the lever is in a bad position to open and close do not adjust the closing force.
WHEEL INSTALLATION 15
STEM ALIGNMENT Make sure the stem is aligned so it’s centered above the front wheel. If it needs to be adjusted, loosen the stem cap bolt and the 2 bolts that clamp the stem to the fork. The bolts don’t have to be removed, just loosened off enough to rotate the stem independently from the fork. Align the stem over the center of the front wheel so they are facing the same direction. Tighten the bolt until there is no play in the fork. Over tightening will make the steering stiff and unresponsive.
STEM ALIGNMENT 5.
HANDLEBAR INSTALLATION Start by removing the faceplate. Set the faceplate and bolts down somewhere accessible. Untangle the cables if necessary. Use carbon assembly gel on the clamping area of the stem and face plate. Center the handlebars in the stem. Hold the handlebar in place. Install the faceplate to clamp the handlebars in place. Tighten bolts gradually in a cross pattern and tighten them to 5Nm.
HANDLEBAR INSTALLATION 5Nm 19
DRIVE SIDE PEDAL INSTALLATION The drive side pedal (marked R) installs on the crank, on the side that has the chainring(s). Apply a thin layer of grease to the threads. Start threading the pedal in by hand, turning it clockwise (towards the front of the bike when viewing facing towards the bike from the drive side). Continue to thread the pedals in using the 8mm allen wrench. Tighten firmly, about 34Nm.
DRIVE SIDE PEDAL INSTALLATION M8 34Nm 21
NON-DRIVE SIDE PEDAL INSTALLATION Non-drive side pedal installation.The drive side pedal (marked L) installs on the crank on the side that does not have the chainring(s). Apply a thin layer of grease to the threads. Start by threading the pedal in by hand, turning it counterclockwise (towards the front of the bike when viewing the bike from the non-drive side). Continue to thread the pedals in using the 8mm allen key. Tighten firmly to about 34Nm.
NON-DRIVE SIDE PEDAL INSTALLATION 34Nm M8 23
BRAKE ADJUSTMENT Verify that the rear brake is working properly. Lift the rear wheel off the ground and spin it. Look inside the caliper to see/ hear if the rotor is rubbing against the break pad. Check that the front and rear brake levers have the same amount of travel when applying the brakes. If the rotor is rubbing, loosen the brake caliper mounting bolts. Squeeze the brake lever and tighten the brake caliper mounting bolts.
BRAKE ADJUSTMENT 25
SADDLE ADJUSTMENT Check the saddle position. The saddle should be level i.e. parallel to the ground and high enough to get near to a full extension of the leg when at the bottom of the crank rotation while maintaining a slight bend at the knee to prevent hyperextension. The saddle height can be adjusted by loosening the seatpost clamp. Typically the appropriate height is close to your hip. When the saddle is at the correct height tighten the seatpost clamp back to 5Nm.
SADDLE ADJUSTMENT 5Nm 27
SADDLE ADJUSTMENT To adjust the seatpost loosen both bolts on the underside of the saddle rail clamp. Adjust the saddle to the desired position. Gradually tighten the saddle rail clamp bolts, alternating between them. Pay attention to how tightening the bolts effects the saddle position.
SADDLE ADJUSTMENT 5Nm 29
TIRE INFLATION Inflate the tires. Find the marking on the tires that indicates the appropriate pressure range for those tires. Remove the dust cap and open the valve. Inflate the tire to the appropriate pressure, then close the valve and put the dust cap back on.
