Assumed M30 would be like GXP and bought a "DMR AXE M30 BSA BB" from CRC for £31. Arrived in a Praxis box with a "DMR AXE etc etc" sticker over the Praxis part info and barcode. Turns out, DMR AXE cranks has a removable driveside, like RaceFace X-type chainsets, whereas my Praxis Turn Zayante M30 cranks have a removable NDS crank, like Shimano HT2.
The bearing's the same on both sides, but there's a 2mm thick sleeve pressed into the bearing on one side. The wrong side.
Option 1: Press out sleeve from right bearing and press it into the left bearing.
Option 2: push both bearings out of their cups and swap them over.
Option 3: remove both bearings, press out the sleeve, buy shiny new bearings, press sleeve into new left bearing, fit new bearings to cups.
Option 4: return to CRC and hope they don't mind the damaged box and sticker, buy normal M30 BSA bb from somewhere else for too much money
