Made with genuine vegetable-tanned leather, each pair of grips is hand-stitched and molded to have the right diameter. The manufacturing process takes 10 days and the final result is distinguished by its careful finishing and a super resistant seam, which results in a natural, comfortable, stylish and long-lasting product. Ideal for classic, touring, vintage, retro and other bicycles. As the dyeing process is 100% handmade, there may be small variations with the colors of the products in the photos. Clarification: The grips require glue for their correct application (instructions included with the product).
