  • Anyone got any good solutions to the new 105 lacking a 46/30 crankset option?

    I can see

    1. Get a separate crank (PiTA)
    2. Absoluteblack overpriced subcompact chainrings
  • I'm waiting t for doval version of slightly oval used 46/30 for Shimano 4 armed cranks. I'll update once it arrived.

    I'll be using them with 5800 or 4700 cranks, the new groups should be the same Bcd right?

  • I think that seems to be the case - it's the crank arm rather than the BCD that looks different. Let me know how you get on! My preference would definitely be to order the whole thing and change the chainrings, but ideally not at wallet snapping cost..
