• Dear Tester,
    Please can you help! I’ve kept up to speed on the latest research regarding chain lubrication and wear and can definitely say that the SILCA synergetic lube , although expensive , does pay as chains really do last much longer , for me. I have read your advice on chains and it has proven to be very useful , thanks!
    Cassettes though - I think I have searched the thread correctly - and ready to be corrected-but is there a difference in wear rate between price points? Ultegra vs 105 vs Microshift? I think my Shimano basic hg400 cassettes in 8/9 speed seem some of the most durable but anecdata troubles me.
    I have sleepless nights searching inter web but not enough google fu to find anything. Please can you help?
