The equivalent Praxis model is M30-THRU which is compatible with 30mm spindle cranks (see list from Praxis below) but these are not Praxis ceramic bearings. Cross seals are great for gravel or cross bikes and can be replaced with road seals if desired. Stand alone bearings msrp for $149. Includes Praxis BB tool. This was a warranty replacement I decided not to wait to receive due to upcoming race event so I had to buy something else local and just decided to keep the other one.
