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:
- Remove thru-axle, wheel, and brake caliper from the fork
- Unscrew the T20 bolt on the drive-side insert, located on inside of the fork. Repeat the step on the non-drive side.
- Reverse orientation of the inserts and reinstall the bolt for each back into the insert and fork. (Torque spec is 2Nm)
- 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
- Affix caliper to the fork, install wheel into the dropouts, and secure the thru-axle
- 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.
