Notes for 42T Sprocket

Notes for 42T Sprocket

If you install cassette larger than 42T(such as 11-44T, 11-46T, etc), you need to install a additional hanger as left image show(2.3cm*4.5cm). We also provide this hanger and please let us know when placing order for this gravel frame.

Latex 3D Mandrel Technology on gravel carbon frame

Latex 3D Mandrel Technology

Use newest one-piece latex 3D mandrel and moulding technology.
Such technology helps to optimize the orthodromic and strength of carbon fiber, and avoid wrinkle inside (wrinkle is a key factor that may cause crack). Even using same material, the strength is improved 30%. 
To achieve same strength, tradition method requires thickness 1mm-1.2mm, while such new technology only requires 0.5mm-0.8mm thickness. Thus, we are able to make the frame about 15% lighter, given strength unchanged.
The left picture shows frame made with tradition technology and new 3D latex technology. For tradition method, it is with many wrinkle and bubble inside(picture A). For 3D latex mandrel which is smooth inside, no wrinkle or bubble(picture B).
