The TMR01 and TMR02 frames have the same external appearance yet use different materials in the production processes. The TMR01 uses more high modulus material, while the TMR02 uses more inexpensive carbon sheets. There is a small weight difference, the TMR02 is on average around 5% heavier for the frame than the same sized TMR01. At the same time, there is a reduction in the stiffness values on the TMR02 as well, but only slightly. This is because of the more economic layup. The seatposts on the two bikes are the same, as is the rear brake.
