DESCRIPTION

ProX C68DB Super Light Full Carbon Spoke Disc Brake Wheels - Unique Butterfly Weave

For the butterfly weave rim, the carbon fiber is overlapped which looks like a butterfly, also named braided/UD X weave/butterfly knot/butterfly effect. The butterfly pattern evenly over the spokes holes which makes a contribution to the strength of the rim wall thickness.
BRD28 series (ProX Butterfly Weave Road Disc 28mm width) carbon rims are made from premium Toray T800+T1000 carbon fiber, not only just overlay them, but involving appropriate proportion and elaborate lay-up etc., which is the basis for light weight. The cost of materials is also higher than the regular T700. The rim weight is around 10g less compared to our other UD weave rims. 
Currently butterfly weave is limited to this rim series only. Both matte and glossy finish are available.

The C68DB hub is made by well-known Taiwan hub manufacturer and with the reliable quality as usual. It is with straight pull spoke system and 20 spoke holes for both front and rear wheel. The weight of hubs is only 265g/pair (XDR) which is light weight. Hubs are designed with DT swiss style Ratchet 36T freehub system which improves power transfer efficiency, combining with ceramic bearings, the rolling resistance is minimized. Such hubs help you to shorten acceleration time and save energy. 

The unique full carbon spoke (only 2.9g/pc!) is customized which is 3.1mm wide aero bladed. Such carbon spokes (model CS1) is lighter but stronger than regular steel spokes. The carbon spokes look similar as regular spoke, except for the carbon fiber material and ultra light weight. The weight of our CS1 carbon spoke plus specific aluminum nipple is only 3.2g, which is about 1.8g lighter than well-known Sapim CX-Ray spoke with nipple. C68DB wheels is allowed to update to with wider carbon spokes(5.5mm width, model CS2) as shown. From wider carbon spoke, it gets more aerodynamic. The wheels weight with 5.5mm width carbon spokes is around 10g added compared wheels with 3.1mm spokes. More than anything, the carbon spoke provides both higher stiffness and better fatigue life compared to the traditional steel spokes. The max spoke tension of the carbon spoke is 528kgf according to our in-lab test, which is much higher than regular steel spokes (typically under 400kgf). Carbon spoke can be made wider and stronger, so we reduce spoke count without losing wheels stiffness.

BRD28 series carbon rims are with 28mm outer (21mm inner) width, with depth 33/38/45/50/55mm optional. No matter you need shallow carbon rims for climbing or deep carbon rims for flat road riding, there is always one for you.
ProX decal/logo is offered for free as showed in ProX decal page. The decal will be applied on the rim and do the matte or glossy finish according to customers' preference. You can choose either with such ProX decal or simply without decal. The rims can be made with your customized logo as well. So it will become your own brand wheels!

We offer Duty Free Shipping option to EU countries.

Please note: Due to the special wheel building tools needed for carbon spoke wheel building, as well as bigger nipple size (around 7mm diameter head, which is larger than Presta valve hole diameter 6.5mm), nipple can not be put into the rim through valve hole. It means No-External-Hole rim can not be built with carbon spokes (which comes with bigger nipple head). Thus, tubeless rim tape is a must if you intend to use tubeless tires. If you prefer No-External-Hole wheels, please choose our other carbon wheels (regular steel spokes).

TECHNOLOGY
Carbon Fiber Material

Carbon Fiber Material

Premium Toray T800 + T1000 carbon fiber are used in our carbon rims. 

Combining with stable resin system to make consistent quality and light weight butterfly weave road carbon rims.

Light Weight

Light Weight

By using well designed lay-up structure, mixing Toray T800 and T1000 carbon prepreg, light weight carbon rims are created.

Excessive materials are eliminated to save weight, while extra materials are added around spoke hole for reinforcement.

So, light weight is achieved without compromise in strength or stiffness.

Narrow Inner Width

Wide Inner Width

Relatively wide 21mm inner width, make it possible to fit multiple sizes of tire.

Normally road tire size 700x28C are recommended (also fit other wider tires).

Tubeless Ready

Tubeless Ready

Tubeless tire is getting popular in road bicycle wheels thanks to its better traction, lower rolling resistance and better riding comfort.

All our carbon clincher rims are tubeless ready (also fit normal tube tires).

Optimized anti-burp bump design provides easy tire mounting, dismounting, as well as air inflation.
