Or only 1 item?** A: Mine was a set of 2. One for the drive side and one for the non-drive side. Make sure you are using it for the correct BB. It must be for a 24mm spindle and 37mm shell. Also, take care not to damage your outer seals. It does not come with new ones ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cheap, smooth *by D***O on January 18, 2024* MR2437s are meany to fit in a bicycle bottom bracket. I was skeptical at this price, half the comps and 10% or the big names. They were smooth, they fit nicely in the BB90, and I'll put in an update if I break them, but they work! ### ⭐⭐⭐⭐⭐ Spin super smooth and fast. *by F***M on May 31, 2024* Put a set of these bearings in my Wheels Manufacturing Bottom Bracket. ABEC 5 ceramic hybrid are the highest rated bearings I can find in this size. I will get another pair so I can always have a clean set ready. ### ⭐⭐⭐⭐⭐ 2017 Domane *by M***. on May 26, 2021* I did not know that I would need spacers and a dust cover. The OEM dust cap fits through the OEM bearing and has a lip that pops out the other side of the bearing to keep it in place. The inner diameter of these bearings is smaller than the OEM bearings, so the OEM dust cap doesn't fit - so, I needed a spacer and dust cap. Fortunately, I got a different bearing kit at the same time as this one that came with spacers and covers. I used these Abec-5 with the spacers/covers from the other kit. ## Frequently Bought Together - 2PCS Hybrid MR2437 Ceramic Bearing | 24377 24X37X7mm 2RS Si3N4 Ceramic Ball Bearing | BB90/95 Road/MTN for SRAM/Truvativ Cranks - Wheels Manufacturing Shimano Bottom Bracket Bearings Sealed 24mm x 37mm Pair Bike Pack Accessories - Park Tool RC-1 Press Fit Retaining Compound for Bicycles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/72848057-2pcs-hybrid-mr2437-ceramic-bearing-24377-24x37x7mm-2rs-si3n4-ceramic](https://www.desertcart.vu/products/72848057-2pcs-hybrid-mr2437-ceramic-bearing-24377-24x37x7mm-2rs-si3n4-ceramic) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-05*
