LightCarbon Mountain Bike Rims 650B Asymmetry Design MTB Carbon Rims

mountain bike carbon rims asymmetric design

Features:

- Asymmetric design, help to equalize the spoke tension between drive side and non-dirve side of wheels.

- Thick side wall design for better impact resistance.

- Radius support nipple bed design, distribute spoke pull force evenly around each spoke hole.

- Ultra smooth inner wall, for even wall thickness and strength.

- Tubeless Ready.

- With super light weight (Graphene) version optional.

Graphene prepreg helps to improve the strength of carbon rims up to about 20% (if weight unchanged), or reduce 15% weight (keep strength unchanged).

LightCarbon MTB rim has passed UCI 120J impact testing (double of UCI standard 60J !)

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: Asymmetric rim VS Symmetric rim

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.
