Wheel Removal:
When removing the wheels, please note that the bars may be turned for fit. Also, it is important to check for Hub end caps before discarding wheel protectors and reinstall end caps on the hub.

Seat Post Installation

1. Detach the seat post and remove the protective foam.
2. Undo the strap around the bottom bracket.
3. Plug Di2 cable into seat post battery, you should hear a click. (Step #1 only required for Shimano GRX Di2 builds.)
4. Insert the seat post into the frame. Ensure the minimum depth of 10 cm is achieved. Carbon paste is not necessary. If you choose to use carbon paste, only apply to the back and/or sides of the seatpost, making sure to avoid the front side and seat post clamp.
5. Torque the BLACK seat post clamp bolt to a minimum of 6 N.m. using a torque wrench. Do NOT adjust the silver retaining bolt. Temperature, moisture, and contaminants can affect the seat post clamp. If necessary, it can be torqued up to 8 N.m.

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 in their most forward position. Follow the below instructions to change to the
“short” position:

1. Remove thru-axle, wheel, and brake caliper from the fork

2. Unscrew the 2.5mm hex bolt on the drive-side dropout, located on the inside of the fork.
   Repeat step on the non-drive-side dropout.

3. Reverse the orientation of each dropout and reinstall on the fork using the same 2.5mm hex bolts. (Torque spec is 2 N.m.)

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 POSITION

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 preferences, 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, most GS1s are shipped with 42mm wide tires (700 x 42) and are setup the “long” position. If you increase your tire width to 48mm (700 x 48), 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.

NOTE: Maximum tire size is 700C x 48mm

FINAL CHECKS & ROAD TEST

1. Install your pedals as per the manufacturer’s instructions.

2. Then check the tire pressure and inflate as per the manufacturer’s recommendation.

3. Adjust the saddle height as necessary, and torque the seatpost clamp bolt to 6
   N. m using a torque wrench. Ensure the seat post minimum insertion depth of 10cm is achieved.

4. 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.

5. Check the operation of the brakes, derailleurs, and steering.
