Greenhouse Heat Test for Carbon Wheels

The rim is placed in a curing oven at 80°C for 4 hours with a tire inflated to 65 psi. Measurements are taken at six evenly spaced points.

Pass criteria

● Outer width change: ≤5%

● Spoke tension loss: ≤15%

Result vs. limit

● Maximum outer width change: 1.2%

● Maximum spoke tension loss: 6%

The measured width change was 76% below the maximum allowed limit. The measured spoke tension loss was 60% below the maximum allowed limit.

For the rider, this means the tested rim retained its shape and spoke tension well within Light Travel’s limits after high-temperature exposure. This reduces concern about heat-related deformation or tension loss under the tested conditions.
