It can take up to 30 days to process a return or refund.

For Standard shipping in the continental US, Ventum uses a custom, oversized bike box and the bike will arrive 98% assembled*. You simply need to install the wheels and seatpost and you’ll be ready to ride. A torque wrench is required.

The Tempus ships slightly less assembled, as the cockpit must be uninstalled from the steerer tube for safe transit in the box.

For bikes shipped outside of the continental US, the bike will arrive 85% assembled. Upon delivery, you will need to install the wheels, seatpost, and the stem onto the steerer tube.

*Supply chain restrictions may result in bikes being shipped in a standard-size bike box, at times, requiring more assembly.

&nbsp

We do not build and ship bikes without wheels. The alloy training wheels are included in the cost of each bike and cannot be removed for a discount.

&nbsp

Currently, chainrings and cassettes are offered in one option for each groupset due to ongoing supply chain issues with the cycling industry.

&nbsp

Yes. Please reach out to support@ventumracing.com to request which seatpost you prefer. Ventum uses the 25mm setback seatpost by default on NS1s, and zero-setback posts on GS1s. NS1 and GS1 seatposts are interchangeable.

&nbsp

The NS1 and GS1 typically feature a Fizik Tempo Argo saddle. The Ventum One Disc uses an ISM tri-specific saddle. Specific saddle models are subject to change based on availability.

&nbsp

Yes. We use a Ritchey 1-bolt saddle clamp on our Ventum models. To install a carbon-railed saddle, you must purchase and install Ritchey’s 7x10 “carbon” clamp: https://ritcheylogic.com/bike/seatposts/wcs-carbon-1-bolt-seatpost-clamp

&nbsp

NS1 builds with the SRAM Rival AXS and Shimano 105 groupset are equipped with a traditional two-piece alloy handlebar and stem, and partial internal cable integration.

Ventum's integrated bars, the CR2 and CR5, will require a center-mount "integrated" mount. Ventum recommends our own Ventum computer mount. Only compatible with the current (2nd Generation) Integrated bar/stem). Contact support@ventumracing.com for more information.

&nbsp

Ventum does not have any recommended clip-on aero bars, as they have not been tested with our integrated handlebar, and the aerodynamic profile of the bars may result in issues with installation and fit. Ventum recommends using a more traditional 2-piece bar and stem configuration with round bars if you’d like to use clip-on aero bars.

&nbsp

The new 12-speed Shimano power meter cranks have been difficult to source. Ultegra power meter cranks are not available at this time, however some Dura Ace power meters might be available for an additional cost. Reach out to support@ventumracing.com for more information

&nbsp

Ventum does not offer this as an upgrade option. However, the Sram Rival power meter upgrade kit can be purchased separately from bike retailers.

The sizes of these items are typically determined by your frame size, and are subject to change, based on availability. Reach out to support@ventumracing.com to request specific sizes, which we’ll install provided that they’re in stock when your bike is built.

FRAME DIAGRAM

Please carefully inspect the image. 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. Please refer back to this image as needed.

ASSEMBLY - SEAT POST OPERATION

Access the seat post clamp on the underside of the frame. Tighten to 6Nm with a torque wrench. 


Carbon pate is not required but may help prevent seat post slipping. If used, apply a small amount of carbon paste to the back and sides of the seat post only. 


Ensure a minimum seat post insertion depth of 10cm. It may be necessary to cut excess seat post length on smaller frames to achieve your desired saddle height. 

ASSEMBLY - SADDLE CLAMP OPERATION

To adjust the position your saddle, loosen the 5mm bolt on the clamp. Once your saddle position is achieved, torque the 5mm clamp bolt to 12 Nm using a torque wrench. 


Ventum’s stock saddle clamp only accepts round, alloy saddle rails. Saddles with oversized or oval carbon rails require Ritchey’s 7x10mm clamp assembly. This clamp works on all saddles with carbon rails ranging from 7x9mm through 7x10mm. (Ritchey part No. 55055467003) 

ASSEMBLY - THRU AXLES

Using a 6mm hex extension on a torque wrench, tighten both thru axles to 10Nm. Do not attempt to adjust the rear thru axle on the driveside of the bike. If you experience brake rotor rub, the thru axles may not be torqued properly

ASSEMBLY - STEM & HEADSET OPERATION

To access your stem and headset, remove the plastic stem cover by removing the 2mm bolts on either side of the cover.


To tighten your headset, first loosen the 4mm stem pinch bolts. Tighten the stem top cap bolt while pulling the front brake lever and rocking the bike back and forth. Stop tightening the top bolt once play in the headset is corrected. Using a 4mm hex extension on a torque wrench, tighten the stem pinch bolts evenly to 5 Nm.

COCKPIT AND EXTENSIONS - ASC PRO / ASC 52 CARBON

ASC PRO EXTENSIONS - The Profile Design 52A alloy extensions feature up to 70mm of vertical pad stack adjustability, up to 15 degrees of positive tilt, and up to 40mm of fore/aft adjustment. See Profile Designs documentation for more information.
