  • I've got a variety of tools that have accumulated over the years, the ones I end up using are the Park tools drift and the Park tools press:

    Drift the bearings out, pull the circlips, clean everything with isopropyl, circlips back in, smear of red teflon grease and press the bearings in. The grease is more superstition than anything I suspect as it gets squeezed out as the bearings go in, but it makes me feel better so I still do it.

    Bearings wise I'd grab whatever gets delivered fast, for a decent price - they all seem pretty similar until you get into the ceramic end of things.

    In terms of further setup it's bang the axle in (more red teflon grease), making sure the axle is the correct way round, bearing shields on held in place with a blob of grease, then spacers (consult PF30 diagram and your frame for the specified alloy ones) then enough .5mm plastic spacers. Enough in this case means that you can't get a .5mm spacer edge-on into the space left by the wavy washer when it is under compression, i.e. the wavy washer has <0.5mm free space between it and whatever it is against (this if it's a Cannondale crank).

  • @dancing james If you don't want to go down the hammertime route you can source a puller like this.

    I've got one of those mini BB presses to do the install but if you have a proper headset press get the adapters for that.

  • i have a headset press, but just don't have callipers to check if they have a 30mm size or if i need to buy 30mm press tools to go onto the headset press.
