My bike came with parts different from the specs listed on the website. Why?

Unfortunately, sometimes components, paint colors, decals, or other materials become unavailable after production has started. When these situations arise, we must make changes after specs and photos have been published. We strive always to make substitutions of the same or higher quality compared to the original.

My bike’s color looks different from what’s pictured on the website. Why?

Different monitors and devices display colors differently. We make every effort to use images that represent the colors of our bikes as accurately as possible, but we cannot guarantee exact consistency between what you see on your display and the true color of your bike.
