The "57CR" is the latest 5-spoke model from the original Gram lights model "57C". It features carefully selected sizes to meet the needs of the sports scene and drift competition. The spoke structure starts from the rim, then concaves toward the center of the wheel, giving stiffness and lightness priority. Also, each rim width features an exclusive concave face design. The 57CR is a classic 5-spoke style, unfazed by trends--it's the perfect pure sports model.
