The R30 is great for mild, drier temperatures. Use by itself or as a base layer for other liquid or block top coats. Rode`s R-line glide waxes are made with eco-friendly fluoro-free additives. They are almost as fast as fluoro waxes even in high humidity! The `R` in R-line stands for `race` so these waxes are great for fluoro-free races. They`re also fantastic for training and everyday use.
