Project 321 Road Disc Custom Handbuilt Wheelset With DT Swiss R500 Rims 700c

Select Project 321 ISO Front Road Disc Hub

Details

The Project 321 ISO Disc Front Hub is a precision engineered work of art that provides everything you could want out of a hub. Thanks to large, equally sized flanges it builds a very strong wheel with an excellent high-low side tension ratio. Lightening holes on the drive side flange create a brilliant aesthetic while also shaving a few grams off. In addition, it still has all of the features that make all Project 321 hubs great such as angled flanges, formed rotor bolt threads, and easy serviceability. 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 year hub shell warranty and 5 year end cap 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.

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.

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.

Description

Your Project 321 road disc custom wheelset with DT Swiss R500 Disc rims 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.
