  • How many horrible deaths will my chainline die if I use a single ring on the outer position of an old rival crank?

  • I’ve been running this, (outer ring, road chain line) and been fine for about a year, with a standard fixed hub... been alright so far! If that’s what you’re asking?

    Approximately 5

  • I'm quite baffled by the concept of chainline on 1xn setups. Wherever you put your chainring on the crank the chain will be "bent" for all but one gear. Ideally I guess you should align the chainring with the centre of the cassette, but if you only use the highest gears once in a blue moon, why not put it further inboard and just deal with the horrible cross-chaining on those rare occasions.

    On the bike that I'm currently building (1x6) I've put the chainring off-centre, relative to the cassette, because I need to compensate for the ridiculously large q-factor of the cranks.
