Bikeswiki

| Resource | Best For | Weakness | |----------|----------|----------| | | Specs, geometry, compatibility | Spotty coverage; some errors | | Manufacturer archive (e.g., Trek’s Archive) | 100% accurate old catalogs | Only one brand | | BikeForums / Reddit | Real-world reviews, problems | Unstructured, hard to search | | Sheldon Brown (RIP) | In-depth mechanical theory | Dated (pre-2008 components) | | 99 Spokes | Comparing multiple bikes visually | Less detailed specs |

Unlike static review sites, the wiki structure allows users to correct manufacturer errors or add "real world" notes about specific models (e.g., noting that a specific frame size has a different seatpost diameter). This crowdsourcing makes the feature more robust over time. bikeswiki
