# Riverside Commuter: Rigid Fork Swap

> Upgrading a Decathlon Riverside hybrid with a TOSEEK carbon rigid fork — ditching the heavy suspension for a lighter, stiffer commute.

> 🚲 Bike: Decathlon Riverside hybrid  
> 🔧 Upgrade: TOSEEK carbon rigid fork  
> 📍 Part 1 of the Riverside upgrade series

My commuter is a [Decathlon Riverside](https://www.decathlon.sg/) — a practical step-through hybrid that handles daily duties: grocery runs, short errands, and the occasional evening spin around the neighborhood. It came with a Zoom suspension fork branded "63 COMFORT," which sounds reassuring until you realize it adds unnecessary weight and flex on smooth tarmac.

## 🔍 Why Swap the Fork

The stock Zoom suspension fork is heavy, vague, and designed for terrain I never ride. On flat Singapore roads it just bobs under pedaling effort and adds dead weight. A rigid fork is the single best upgrade for a hybrid used primarily on pavement:

| Stock Fork | Rigid Fork |
|---|---|
| Zoom coil suspension | TOSEEK carbon |
| ~1.8 kg | ~0.5 kg |
| Flex under braking | Direct steering feel |
| Seals & stanchions to maintain | Zero maintenance |

## 🆕 The Fork: TOSEEK Carbon Rigid

I went with a [TOSEEK carbon rigid fork](https://www.aliexpress.com/item/1005004954479868.html) from AliExpress. Key specs that had to match the stock geometry:

![The TOSEEK rigid fork — matte carbon finish, post-mount disc brake tab, and an expander plug for the carbon steerer.](https://hayorov.me/riverside-upgrade/toseek-fork.png)

![Technical drawing showing the 470mm axle-to-crown (29\"), 28.6mm steerer, 100mm hub spacing, and 45mm rake.](https://hayorov.me/riverside-upgrade/toseek-specs.png)

| Spec | Value |
|---|---|
| Steerer | 1-1/8" (28.6mm), 300mm |
| Axle-to-crown | 470mm (29") |
| Brake mount | Post mount, 160mm rotor |
| Dropout | 9mm quick-release |
| Tire clearance | 70mm internal |

> **Note:** The fork came with an expander plug for the carbon steerer — the correct way to compress the headset. Never use a star nut on carbon.

## ⚖️ Old vs. New

## 🛠️ Setup

The swap is straightforward if you have basic tools and a crown race setter:

1. Remove the front wheel, brake caliper, and stem.
2. Drop out the old fork, pull the crown race.
3. Set the crown race on the new fork *(press fit — use a PVC pipe or proper tool)*.
4. Insert the new fork, stack spacers, tighten the stem.
5. Reinstall brake caliper — realign pads to the rotor.
6. Install the expander plug inside the carbon steerer **before** compressing the headset.

> **Tip:** Double-check the steerer length before cutting. Measure twice — you cannot undo a cut on carbon.

## ✅ Result

The 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.

## 🔮 What's Next

With the front end sorted, the next weak link became obvious — the stock B'Twin square-taper crankset and bottom bracket. In [Part 2: Shimano CUES Drivetrain Swap](https://hayorov.me/posts/riverside-commuter-shimano-cues-drivetrain/) I replace the drivetrain with a Shimano CUES 1x setup for smoother shifting and a cleaner chainline.
