  • Looking to build up a 1x system on a roadbike.

    Going to get an apex 1 derailleur and shifter. Also going with the 1030 11-42t cassette.

    Theoretically with a standard chain what is the largest chainring I could run?

    I have a carbon chainset that's 130bcd and their cx1 chainrings smallest tooth count is 52 in that bcd.

    Will I get away with it?

  • standard chain

    Which standard? Some are 112 links and others are 116. 112 will be tight on 52/42 unless your stays are under 390mm. You can always make a longer chain from two short ones, using two quicklinks.
