Shimano Ultegra 6800 Build Kit with Custom Wheels - DT Swiss 240S Hubs, Nox Falkor 55R Carbon Rims

Select Ultegra R8000 Dual Control Shifter

Details

The new Shimano Ultegra ST-R8000 Dual Control Levers allow for more accurate and precise shifting. It has a greater reach for adjusting your brake and gear levers, while the redesigned internal shifting unit ensures a quick and intuitive rear-shifting operation. When paired with the new FD-R8000 front derailleur, your front shifting will be even lighter.

Weight: 438 grams
11-spd compatible

Select Ultegra R8000 Front Derailleur

Details

The Shimano Ultegra FD-R8000 Front Derailleur provides for ultra-smooth shifting, flawlessly moving your chain up and down your crankset without extra effort. The result is a shift that is precise and direct, with no delay. With a revised actuation ratio in combination with the ST-R8000 shifter and polymer-coated cables, the Shimano Ultegra FD-8000 front derailleur delivers both a shorter stroke at the lever and reduced effort. A redesigned pull arm offers more direct and easy shifting, with equal shifting effort across the range, and stability has been improved with a new support bolt.

For use with double crankset
Braze-on, 31.8/28.6 adaptor, or 34.9
Weight: 92 grams (braze-on)

Select Ultegra R8000 Rear Derailleur

Details

The Shimano Ultegra RD-R8000 SS Rear Derailleur creates a reduction in shifting effort at the lever, at the same time remaining sure, quick and precise. Due to the integrated Shadow RD Technology with its race-proven, low profile design, the derailleur is more compact and fits closer to the frame, ensuring less damage in a crash.

Minimum Sprocket: 11 tooth
Maximum Sprocket: 30 tooth
For double gearing configurations
Weight: 200 grams
11-speed compatible

Select Ultegra R8000 11-spd Cassette

Details

Superior choice is at the heart of Shimano's rider-tuned philosophy, and the Shimano Ultegra CS-R8000 11-speed Cassette reflects that philosophy with gear combinations of 11-25T, 11-28T, 11-30T, 11-32T, 12-25T, 14-28T and 11-34T (CS-HG800-11), giving you all the options you need to tune your ride. The Shimano Ultegra CS-6800 11-speed cassettes use Hyperglide sprockets with revised tooth profiles for reduced wear and lightning quick shifts. A rigid aluminum carrier keeps the cogs in check for improved shifting under the most demanding gear changes. The available ratio combinations work extremely well with standard or compact cranksets. 11-32T gear ratio requires the use of a medium cage rear derailleur.

Select Ultegra R8000 Brake Calipers

Details

The new Shimano Ultegra BR-R8000 Dual-Pivot Brake Calipers offers a very sleek design, with narrower gaps between the arms. The wider clearance makes it compatible with larger tire sizes such as 28C. The stabilizer between the axles reduces deformation and improves the braking efficiency, offering a clear contact feeling with balanced rigidity, weight and stopping power. Cable and Housing not included.

Weight: 360 grams (Front & Rear)

Select Shimano CN-HG700-11 Chain

Details

The Shimano CN-HG701 11-speed chain gets Shimano's symmetrical design for super-smooth shifting and improved durability. The redesigned inner and outer links are optimized to efficiently shift under hard loads and virtually eliminate "chain suck." Features Shimano's PTFE coating for increased durability and corrosion protection. Quick Link included. 253 grams.
Select Ultegra R8000 Crankset

Details

The Shimano Ultegra FC-R8000 HOLLOWTECH II Crankset receives numerous technologies from Dura-Ace R9100 along with shaping which further enhances ULTEGRA'S 4-arm design. Shimano's Rider Tuned chainring combinations offer multiple gearing configurations via a singular BCD platform for excellent versatility. With redesigned chainring tooth profiling first introduced for DURA-ACE R9100, the ULTEGRA FC-R8000 Crankset is optimized for the latest disc brake frame designs without the need to increase q-factor. The optimized lightweight crank arm design produces excellent power transfer efficiency, while the redesigned chainring tooth profiling increases clearance between chain and leading teeth to also provide compatibility with frames featuring 135mm O.L.D. and 410mm chainstay length. 11-speed compatible.

Select Nox Falkor 55R Front Rim 700c

Details

The NOX Falkor 55R Road Carbon Rim is a CFD and tunnel proven lightweight deep carbon 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 the in the fastest combination. The Falkor 55R features NOX 2nd generation rim brake surface. The 12K fabric weave on the brake track is not just visually striking; it works in conjunction with the 2nd generation high temperature resin to provide more consistent modulation and brake pad friction while dissipating extreme temperatures better than any other rim NOX tested. The Falkor 55R can be run with tubes or is compatible with tubeless road tires. NOX recommend using Swiss Stop Black Prince EVO pads exclusively with NOX rims. Rim features 28mm external width, 18mm internal and 55mm depth. Lifetime warranty and crash replacement policy.

Select Number of Front Spokes - 24, 28 or 32

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

This Shimano Ultegra 6800 Build Kit provides all of the components you'll need to build your frame into a complete bicycle, including custom handbuilt wheels. To begin, pull up our Build Kit Guide and become familiar with your bicycle's technical specifications (ie. headset size, bottom bracket type, crank length and chainrings, cassette configuration, etc.) There are a number of things to figure out, but it should be enticing to get really dialed-in with your bike. If you have questions about the components you need for your frame or bike, contact the company where you purchased it and go through the specification list. Another good idea is to visit the manufacturer's website to research your frame or bike. Manufacturers often have archived files that provide specs on older models. Once you're familiar with the technical specifications, the process should be easy.

Your DT Swiss 240S custom wheelset with Nox Falkor 55R Carbon 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 tubless 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.
