The dropouts and cable stops are well made. Lake Blue is a head turner. Arrived in Boston safe and sound. No customs headache. Highly recommended.
No chips or scratches. The paint is thick and glossy. Delivered to San Diego quickly. The fact there is no import tax makes it a steal.
용접 부위가 매끄럽게 처리되어 있어서 카본 프레임 같습니다. 레이크 블루 색감도 아주 고급스럽네요. 배송 상태도 완벽했습니다.
写真で見るより実物の方が断然かっこいいです。軽量で作りもしっかりしています。海外通販ですが、届くのも早く安心できました。
Customer service helped me pick the right size. The Lake Blue is vibrant. Shipped to Sydney pretty fast. Good value for an alloy frame.
The box was reinforced and everything inside was wrapped in foam. The frame itself is gorgeous. No duty for US customers is real. Very happy.
Got this for my son’s bike build. He loves the color. Frame is straight and threads are clean. Fast delivery to Philadelphia with no tax issues.
