FRAME DIAGRAM

Please carefully inspect the diagram below. It gives you a thorough break down of the names of the tubes that the frame/fork consist of and the components that this bike uses.

GS1 Frame Diagram Chart
GS1 Frame Diagram

UNBOXING

Remove the parts and support cover. Then remove the top tube foam blocks and shifter blocks.

WHEEL REMOVAL

Remove the straps and foam blocks from the wheels. Note bars may be turned for fit.

Next remove the wheels from the box and remove the hub guards.

SEAT POST INSTALLATION

First detach the seat post and remove the protective foam. Next undo the strap around the bottom bracket.

  1. Plug Di2 Cable into seat post battery. You should hear a click. Disregard this step if your build does not included Shimano Di2.
  2. Insert the seat post into the frame. Ensure the minimum insertion depth of 10cm is achieved.
  3. Torque the seat clamp bolt to a minimum of 8 N.m. Temperature, moisture, and contaminants can affect the seat post clamp. If necessary, it can be torqued up to 10 N.m.

NOTE: To remove or adjust the seat post, loosen the seat post clamp bolt. It is not necessary to remove it from the clamp entirely. Simultaneously tap the tail and nose of the saddle with your hands to disengage the clamp’s grip on the seat post and permit adjustment. Push or pull the seat post as required to achieve the desired saddle height.

WARNING - Failure to follow these instructions could lead to serious injury or death.

TORQUE SPEC

 

Tighten to
8 N.m.

 

Do no over tighten this component!

FRAME UNBOXING

Remove the straps from the handlebar. Next lift the frame out of the box. Finally detach teh strap and foam block from the crank arm.

WHEEL INSTALLATION

Unscrew the thru axles from the frame and fork using a 6mm hex tool. Next remove the spacers from the brake calipers. Install the wheels ensuring the brake rotor lines up between the brake pads. Finally secure the wheels by re-intalling the thru axles. Torque to 12 N.m.

WARNING - Failure to follow these instructions could lead to serious injury or death.

THE DUAL-OFFSET FORK

Your Ventum GS1 comes equipped with our Dual-Offset Fork. This fork has a 2-position front dropout that allows the rider to adjust the fork offset (effective steering geometry) to fine-tune their ride characteristics. The 2-position system comes with 5mm of fork offset adjustment.

Your GS1 will come pre-assembled in the "long" position. This is with the dropouts.

Follow the below instructions to change to the "short" position:

  1. Remove thru-axle, wheel, and brake caliper from the fork
  2. Unscrew the T20 bolt on the drive-side insert, located on inside of the fork. Repeat the step on the non-drive side.
  3. Reverse orientation of the inserts and reinstall the bolt for each back into the insert and fork. (Torque spec is 2Nm)
  4. Add the 2 included 5mm spacers between the adapter plate and the fork (Torque spec is 6-8 Nm)
    Note: In both configurations, the adapter plate MUST remain orientated with “140” at the top of the plate
  5. Affix caliper to the fork, install wheel into the dropouts, and secure the thru-axle
  6. Adjust caliper (as needed) to align with the brake rotor

WHY CHANGE THE POSITON?

We know different riders have different priorities, so we took handling preferences one step further with the Ventum Dual-Offset fork. The ideal position of the Dual-Offset fork will be dictated by rider preference, terrain, and tire selection.

All other things equal, in the “long” position, your steering is more deliberate, wheelbase is a little longer, and your handling will be more stable and predictable. This is great for confidence on long gravel descents or really long days in the saddle. In the “short” position your steering response will be quicker and the steering will feel livelier. This is great for riding with tight turns (such as on single track or cyclocross), riding exclusively on the road, or if you really enjoy snappy steering.

Effective tire size will also play a part in your handling and may also affect which position you want to use. As the tire size increases, your steering response gets slower. For example, your GS1 comes shipped with 37c width tires and is in the “long” position. If you increase your tire size to 42c width tires, your steering will become slower, and you may want to set the chip in the “short” position to offset this change. Conversely, if you use narrow tires, such as 32c width, the steering will be livelier, and you could counteract that by positioning the fork dropout in the “long” position.

No matter what riding style you prefer, the GS1 lets you dial in your ride.

FINAL CHECKS AND ROAD TEST


  1. Install your pedals as per the manufacturer’s instructions.
  2. Add included Stan’s Tire Sealant (1 bottle for each wheel) Installation Video.
  3. Then Check the tire pressure and inflate as per the manufacturer’s recommendation.
  4. Adjust the saddle height as necessary. Ensure the seat post minimum insertion depth of 10 cm is achieved.
  5. Put on your shoes and helmet and take your new bike out for a road test. Always wear a helmet when you ride your bicycle.
  6. Check the operation of the brakes, derailleurs, and steering.
