Project 321 Road Disc Custom Handbuilt Rear Wheel With NOX Falkor 55D Disc Carbon Rim 700c

Select Project 321 CX1 Road Disc Rear Hub

Details

The Project 321 CX1 Rear Hub was designed with Cyclocross and gravel grinders in mind. Essentially, it is their well-designed G2 Hub with some tweaks to allow the compatibility to run a road style 10/11 speed cassette. This means you can keep riding drop bars and integrated levers and get all of the benefits of Project 321 exquisite hubs. You still get all of the great features such as a revolutionary drive system, high capacity oil chamber, angled flanges, brilliant finishing, tension adjustable axle, and high quality bearings. All Project321 rear hubs are now equipped with the new magnetically actuated, 6 pawl, ratchet drive system. This new system gives you a combination of options and features like no other drive system on the market. The angled flanges allow the spokes to touch the hub only at the bend and nowhere else. This creates a more stable and true wheel and eliminates any unnecessary stress on the spokes. Rotor bolt holes are form tapped which creates a stronger, cleaner thread than the more common method of cut tapping. 10 years on hub shell and axle, 3 years on pawls, drive ring, and free hub body and 1 year Enduro bearing warranty. (For original owner only; does not apply to anodize fading). Project 321 hubs feature a CNC engraved logo and comes standard with 2 high precision Japanese cartridge bearings. Available in all 10 color options with long lasting anodization. Made in the USA.

Select NOX Falkor 55D Road Disc, Rear 700c

Details

The NOX Falkor 55R Road Carbon Disc Rim is a CFD and tunnel proven lightweight deep carbon disc clincher for road racing, triathlons and just riding fast. The Falkor 55 rim is the result of a new design process NOX calls Weighted Performance Matrix (WPM). WPM is an internal process in which all aspects of a rim are evaluated during the design phase. Design parameters include the type of bike it will be on, the terrain, the hubs it will be built with, typical head and cross winds, tire sizes, average rider weight and more. In the end NOX ended up with a matrix with over 20 parameters and use this to fine tune aspects of the rim so that the performance is optimized for the specific application. In short, the science drives the design rather than the marketing department. Every aspect of the Falkor rims from the rim profile to the carbon layup schedule to the spoke exit angle is designed using this philosophy. The Falkor 55R is aerodynamically optimized for 25mm tires, however tires ranging from 23-28mm will fit without problems. The inner width of 18mm and the outer width of 28mm create a seamless tire to rim transition at 25mm which is the key to maintaining laminar airflow around the leading and trailing edge of the rim. The use of a lightweight 25mm tire will also lower rolling resistance over most real-world road surfaces resulting in the fastest combination. The Falkor 55R can be run with tubes or is compatible with tubeless road tires. Rim features 28mm external width, 18mm internal and 55mm depth. Lifetime warranty and crash replacement policy.

Select Number of Rear Spokes - 24 or 28

Details

High spoke counts (having a lot of spokes) and 3X lacing increase the robustness and durability but come with a weight penalty (heavier). Low spoke counts (having less spokes) and 2X lacing decreases the robustness and durability but come with a weight advantage (less weight). You can run a lower spoke count on carbon rims because of the stiffness/strength of carbon. If you need some help or advice, feel free to call or email us. We'll make recommendations based on your unique needs. 1-800-688-8600 or support@coloradocyclist.com.

Description

Your Project 321 road disc custom rear wheel with NOX Falkor 55D Disc Carbon rim is proudly handbuilt in Colorado Springs, Colorado, USA.
Every wheel we turn out is built completely by hand to your specifications. All wheels are tensioned, stress-relieved, then re-tensioned before final truing. We have been building custom wheels since 1977 and take great pride in building the finest wheels available.

These rims can be used with standard tires and tubes, or tubeless tires. (For tubeless ready, please order tubeless tape and valves.) Never exceed your tire's recommended tire pressure.

Please Note:

  • Our wheels are built with a 2-cross or 3-cross lacing pattern (3-cross recommended.)
  • If you intend to use tubeless tires, make sure to select tubeless tape (from the rim tape pull-down menu) and to purchase tubeless valves (available in optional items at the bottom of your build.) Further, select tires from the "Tubeless Ready" tire selection.
  • If you choose to select optional items they will be installed on your wheels (with the exception of the sealant) unless otherwise specified. The sealant is not added because it can leak during shipping. If you are picking up your wheels at our retail location, we can add the sealant for you.
  • Manufacturer warranties are honored for the parts included in your build.
  • Custom wheels typically ship from our shop between 1-3 weeks after you've placed your order depending on how busy our shop is. However, if a part is not immediately available - from us or from our vendors - your build may take longer. We do our best to keep you updated on the situation, and are always happy to provide updates if you reach out. The easiest way to contact us for updates is to send us an email to support@coloradocyclist.com and we will respond as quickly as we can.
Nipple Information
Alloy nipples are much lighter than brass nipples (approximately 20g per wheel) and are recommended for light weight builds. Brass nipples are stronger and less expensive. We've been successfully building wheels with both for many years.

Spoke Information
Colorado Cyclist primarily uses DT Swiss stainless spokes in our builds. This has been our choice for wheel building since the late 1970's and we certainly owe part of our wheel building success to the strength and longevity that DT Swiss spokes offer. We also use the very popular, lightweight and bladed Sapim CX-Ray spokes and have had excellent success with them. Spoke weight, as well as a spoke Performance Chart, are provided in the pull-downs that you'll use to pick your spokes. The Perfomance Chart should be used as a guide to compare the various spokes. However, there are so many variables involved in building a wheel properly (ie. rider weight, terrain, intended use, price, etc.), you may end up with questions. If you need some help or advice, feel free to call or email us. We'll make recommendations based on your unique needs. 800-688-8600 or support@coloradocyclist.com.
