For disc brake carbon rims, it not only means simply removing the brake track, but also adjusting rim lay-up design to make it lighter so as to keep overall system weight competitive.
XTDC25 series (XT Road Disc 25mm width) carbon rims are made from Premium Toray T700 carbon fiber +  stable resin system, which is the basis for light weight.
In addition, we optimize the lay-up design, eliminate excessive materials to save weight, and add extra materials around spoke hole area for reinforcement.
Thus, our road carbon rims are light weight, but still strong and stiff.
XTDC25 series carbon rims are with 25mm outer (18mm inner) width, with depth 38/45/50/60/80mm optional.
No matter you need shallow carbon rims for climbing or deep carbon rims for flat road riding, there is always one for you.

Effective Rim Diameter (ERD) is the maximum distance that spokes need to bridge going from one end of the rim to another. How do we calculate the ERD of our rims? The corresponding equation and a drawing is as shown:
ERD=OD-(rim depth)*2+(rim thickness)*2
For example:
ERD of XTDC25-30C rim=633mm-30mm*2+3.5mm*2=580mm
Most people prefer ERD including the length of the nipple cap. However, customers may use different nipples and components for building. Please add the height of the nipple cap(2.5mm~3mm generally) for your spoke calculation. If the height of the nipple cap is 3mm, then ERD of your PRD25-30C rim is 580mm+3mm*2=586mm
A: Rim nipple bed thickness (=3.5mm)
B: Length of nipple cap (2.5mm~3mm generally)

Customized Color Painting/Logo
The customized color painting/logo is acceptable.
The painting cost of frames mainly consist of two parts: water decal cost + color paint and coating cost. The water decal is used for letters (brand mark, logo or other words), and color paint is used on larger area position on the frame.
