Frequently Asked Questions

Q: What bike types is the 6805-2RS bearing compatible with?

A: The 6805-2RS deep groove ball bearing (25×37×6 mm) is widely used in bicycle bottom brackets across road bikes, mountain bikes, gravel bikes, and BMX bikes. It is also compatible with other mechanical applications that require a 25×37×6 mm sealed bearing.

Q: What does "rubber sealed (2RS)" mean, and why does it matter for cycling?

A: "2RS" means the bearing has rubber seals on both sides. These seals lock in the pre-applied grease while keeping out dirt, mud, and moisture — all common conditions during cycling. This results in a longer-lasting, smoother-running bearing with less maintenance required.

Q: How many bearings are included in the package?

A: You can choose between a 1-piece or 4-piece package at the time of purchase. Buying a multi-pack is ideal for replacing bearings on both sides of the bottom bracket simultaneously or keeping spares ready for future servicing.
