  • I checked it on the Praxis website and saw indeed 28 mm for the non driveside.. the bottom bracket arrived today but it actually has 30 mm on both sides (however I had no patience at all so I already ordered a CeramicSpeed bb too, so either one will be returned)

    ^thanks all, bike indeed needs a new crankset but above all a newer bb type instead of the non cardridge ball bearing one, no idea what it's called but it's an old standard.

  • Ok good! I wasn't aware they made 30mm throughout BBs. Also didn't pop up on my admittedly lazy Google.

    Btw, I test fitted my crank this weekend and a 125mm is approx 8mm too long without BB spacers. I reckon the 119mm would be perfect, also regarding chainline.

    Have you installed it yet? Am curious!

  • Not yet, I'm waiting for the shimano and ceramicspeed bottom bracket tools to arrive.

    I did measure the space between the two crank cups, that's approx 88/89 mm with the 119 axle. And the width of the new bottom bracket bearing cups is around 11 mm p/side. So 68 mm bb + 11 + 11 = 90 mm so hopefully it fits.

    Chainline probably will be a problem because the chainring has a large offset. I might turn the chainring around if thats possible or buy another chainring
