• What rivnut should I use in an aluminium bike frame? ('94 cannondale M500)

    Got a spinner on the downtube bottle cage mounts. I got the bolt out, I have a dremel, I have a friend with a rivnut setter that can do M5.

    Just need to source the correct rivnut? anything else I'm missing?
    Also I haven't got the bike apart right now, but I seem to remember the downtube junctions with BB housing and head tube only have small openings... any tricks to not have a rattly bike?

    Use aluminium ones, stainless while they may seem a better option are much harder to set

    ensure you buy open ended ones and not closed end.

    drilling size is 7.1mm if needed
