I am currently in the process of building up a bike.
How much does the 105 groupset weigh?
How much does the Ultegra groupset weigh?
Im thinking of a combination of the two using Ultegra for the drive train


  • Not enough difference to worry about :wink: Sure a full drinks bottle will make more weight difference :) Buy best shifters and mechs, the chainset and cassette not that much to chose between the two.

  • Dura Ace 7900 - 2087g
    Dura Ace 7800 - 2222g
    Current Ultegra (6700) - 2301g
    Prev. Ultegra - 2452g
    Prev. Ultegra SL - 2345g
    105 (5600) - 2559g
    105 (5700) - 2481g
    Tiagra - 2770g

    Approximate & dep. on cassette size, chain length, short or med mech & claimed or actual test 'wet' (oiled) weight.

    Ugrading the chainset to Ultegra (or another alternative) would be the most cost effective weight saving (Ultegra nearly 100g lighter than 105).
