It is also compatible with other mechanical applications that require a 25×37×6 mm sealed bearing.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does \"rubber sealed (2RS)\" mean, and why does it matter for cycling?\u003c\/h4\u003e\n\u003cp\u003eA: \"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.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How many bearings are included in the package?\u003c\/h4\u003e\n\u003cp\u003eA: 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.\u003c\/p\u003e\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What bike types is the 6805-2RS bearing compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"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.
