SKF MTF9 Custom high grease fill bearings - The best on the market

Or....

Hybrid Ceramic bearings with custom specification from our bearing factory we have worked with for over a decade. Spending 10 times more doesn’t give you watts of drag reduction as much as they claim in their adverts!

All bearings 2RS sealed, none of this "light contact low friction" rubbish which doesn’t actually seal and kills your bearings super fast. (don’t believe any of the spinny crank video snake oil, it just shows massive clearances and grease/seals which don’t function which are red flags...)

High grease fill for durability with our custom German made waterproof grease specified. your cranks don’t do 15,000rpm in real life so packing them full wont cause any problem!

Replaceable bearings, just pop them out and press in new ones. 24mm axis is 6805 2RS size

Simple, great value and no marketing guff....
