About SKF bearings Version（SKF bearing ring + G3 silicon nitride ceramic balls）:
SKF bearings are the leader in bearing technology and manufacturing. SKF bearing rings have the advantages of higher rated load, lower noise, greatly reduced maintenance costs, and increased machine running time. Choose it, you can make the riding experience more comfortable and happy. Compared with our other bottom brackets, it has two outstanding features: ① The better wear resistance of the SKF steel ring ② The better sealing and waterproofing of the bearings. and for the ceramic bearings we use non-skf brand silicon nitride ceramic beads, making our skf bottom bracket more cost-effective.
About G3 Silicon Nitride Ceramic Beads :
It highlights the higher strength and impact resistance characteristics of Si3N4, making it better than metal bearings, Secondly, their better wear resistance and heat resistance, light weight and smoothness, making the cranksets smoother during rotation. Be loved and recommended by cycling enthusiasts.reducing friction.
Maintenance of bearings
* Recommend professional bike work shop rebuild .
* Normally do not need remove bottom bracket from bike frame.
* Please follow the recommend maintenance instruction
Please follow the steps to maintain the bottom bracket for a longer lasting use.

2. Clean the bearing surface.
3. Remove the rubber side cover from the bearing with a knife or thin sheet.
4. Use industrial alcohol to clean bearing rollers and cages.
5. After cleaning, please fully inject the bearing grease into the bearing to fill all the gaps.
6. Reset the rubber cover , and then coat the outer surface of the bearing with waterproof grease.
7. Reset the black plastic cover of the bottom bracket and apply waterproof grease to the surface of the side cover.
8.Complete the maintenance.
When to maintain
Riding in wet and muddy conditions requires bearing maintenance every 1000-3000 kms
Riding in a clean and dry environment requires maintenance every 5,000 kms
