UD/3K(customized painting acceptable)LightCarbon Undulating Asymmetric Design 29er MTB Carbon Rims
There is a wide variety of carbon MTB bike rims on the market, so we have introduced the unique undulating rim (UAD935). The rim edge has different depths--(22mm measured from spoke hole area, 25mm measured from bulge). Rims profile fluctuates up and down by 3 mm, allowing cyclists to achieve better aero performance and crosswind stability. You can ride more steadily and safely in the wind.
Features:
- Only available in 29er and fixed 28 spoke holes at present.
- Super light model: UAD935GP-XC made from Toray T700+T800+Graphene (Max weight limit 100kg/220lb).
- Standard weight model: UAD935-XC made from Toray T700 (Max weight limit 120kg/265lb).
- Tubeless compatible: the bead lock design allows for easy switching between clincher and tubeless setup.
- Hookless design provides a more consistent carbon fiber structure at the rim wall. This enhances the durability of the rim and increases its impact resistance. It also provides better grip and sidewall support when cornering.
- Asymmetric rim profile design significantly balances the spoke tension between the drive side and the non-drive side, resulting in a stronger wheel structure that lasts longer.

*ERD Calculate
ERD is short for effective rim diameter, it is the maximum distance that spokes bridge going from one end of the rim to another. How do we calculate the ERD of our rims? Below are calculation equation and sketch for your reference:
Most people prefer ERD including the length of the nipple head.
However, customers may use different nipples and components for building.
Please add the length of the nipple head (2.5mm~3mm generally) for your spoke calculation.
If the length of the nipple head is 3mm, then ERD of your UAD935-XC rim is 589mm+3mm*2=595mm
A: Rim nipple bed thickness (=3mm)
B: Length of nipple head (2.5mm~3mm generally)

Graphene Prepreg VS Regular Prepreg
Graphene prepreg helps to improve the strength of carbon rims up to about 20% (if weight unchanged),
or reduce 15% weight (keep strength unchanged). Above is the testing result.

Why Asymmetric Design?
Asymmetric design is becoming a new trend in mountain bike rims.
Wheelsets built with asymmetric rims are of better strength, stiffness and durability.
The main advantage of asymmetric rim is: it helps to equalize the spoke tensions between drive side and
non-drive side of wheels.
How? Please refer to below illustration:
In mountain bike wheelsets with disc brake, the center of rear hub (Point A) is not in the same position of the center of flange (Point B). The center of hub (point A) is closer to the drive-side. During wheel truing, in order to get hub to the center of rim, the spokes are pulled to higher tension on drive side (compared to non-drive side).
Similarly, in MTB front wheel, the center of hub is closer to the disc rotor side (non-drive side), which makes the non-drive side spoke tension higher than drive side.
The spoke tension difference is normally as large as 40%! Such big difference makes the wheelset weaker as it could be.
As the higher spoke tension side always break easier, while the lower spoke tension side always loose easier.
Asymmetry rims are made to solve such issue.
In asymmetric wheels, the bracing angles are improved by make the nipple holes offset to the center.
Thus, the spoke tension between drive side and non-drive side is much more equalized.
Our asymmetric rims are with 2.6~3.5mm offset from the center (a bit different for different width of rim), which helps to improve the spoke tension over 20%.
Therefore, wheelsets build with our asymmetric rims are of better strength, stiffness, and will stay true longer.
