The weight and bulk difference is obvious.](https://hayorov.me/riverside-upgrade/forks-comparison.png)\n\n---\n\n## 🛠️ Setup\n\nThe swap is straightforward if you have basic tools and a crown race setter:\n\n1. Remove the front wheel, brake caliper, and stem.\n2. Drop out the old fork, pull the crown race.\n3. Set the crown race on the new fork *(press fit — use a PVC pipe or proper tool)*.\n4. Insert the new fork, stack spacers, tighten the stem.\n5. Reinstall brake caliper — realign pads to the rotor.\n6. Install the expander plug inside the carbon steerer **before** compressing the headset.\n\n> **Tip:** Double-check the steerer length before cutting. Measure twice — you cannot undo a cut on carbon.\n\n---\n\n## ✅ Result\n\nThe bike feels noticeably lighter at the front and steers with more precision. Braking is more direct without the fork compressing. For a commuter that lives on tarmac and park connectors, it is the right call. The ride is marginally harsher over bumps, but nothing the 38mm tires at lower pressure cannot absorb.\n\n---\n\n## 🧾 Gear\n\n| Part | Link | Price |\n|---|---|---|\n| TOSEEK Carbon Rigid Fork 29\" | [AliExpress](https://www.aliexpress.com/item/1005004954479868.html) | ~80 SGD |\n| Decathlon Riverside hybrid | stock | — |\n| B'Twin Trekking Speed 700×38C | stock | — |\n\n---\n\n## 🔮 What's Next\n\nWith the front end sorted, the next weak link became obvious — the stock B'Twin square-taper crankset and bottom bracket.
