Features MFR technology has excellent penetration, is oxidation & corrosion inhibiting, and sheds contamination. ProGold incorporates MFR technology into its entire line of bicycle products. ProLink Chain Lube greatly reduces friction & wear, allowing smoother operation of your chain & cables. Prolink will keep your chain & drive train area clean & seemingly drag free.
