Review: Cannondale Topstone Replacement Bottom Bracket - Note this is a replacement bottom bracket for my Cannondale Topstone 105 Alloy 2020. So far for the first month it has been really good, works as it's suppose to without any creaking or play at the bottom bracket location. The last FSA bottom bracket (came stock on the bike) was also good and lasted many years including my recent entire cross country trip from San Francisco to NYC Review: Great product. Nice and smooth! - This worked perfect for my Giant Rapid2 . Make sure you measure the width of the bb before ordering so you get the size right, or go by the markings on your original. This was an exact replacement for mine. ## Features - 200-1893 - 68mm - ENGLISH - 1.37"x24T ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B007M0AYN4 | | Best Sellers Rank | #531,340 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #338 in Bike Bottom Brackets | | Brand Name | FSA | | Color | Black | | Customer Reviews | 4.6 4.6 out of 5 stars (167) | | Finish Types | Black | | Global Trade Identification Number | 00400310019998, 04710636259999 | | Included Components | No | | Item Depth | 15.0 centimeters | | Item Dimensions | 5.91 x 2.36 x 2.36 inches | | Item Type Name | FSA BB-4000 Omega Drive MegaExo Bottom Brackets - Black, 68 mm | | Item Weight | 200 Grams | | Manufacturer | FSA | | Manufacturer Part Number | 200-1893 | | Material Type | Alloy Steel | | Model Number | 200-1893 | | Mounting Type | Wall Mount | | Set Name | MegaExo | | UPC | 400310019998 822051250865 | ## Product Details - **Brand:** FSA - **Color:** Black - **Item Weight:** 200 Grams - **Item dimensions L x W x H:** 5.91 x 2.36 x 2.36 inches - **Material:** Alloy Steel ## Images ![FSA Mega Exo 19 Bottom Bracket #BB-4000 - Image 1](https://m.media-amazon.com/images/I/61ieVF+t+OL.jpg) ![FSA Mega Exo 19 Bottom Bracket #BB-4000 - Image 2](https://m.media-amazon.com/images/I/61-jul7CtRL.jpg) ![FSA Mega Exo 19 Bottom Bracket #BB-4000 - Image 3](https://m.media-amazon.com/images/I/61p7l1AANOL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Cannondale Topstone Replacement Bottom Bracket *by K***N on September 29, 2025* Note this is a replacement bottom bracket for my Cannondale Topstone 105 Alloy 2020.
