A Practical Entry Point into Road Cycling

The Camp Radon X is positioned as an entry-level road bike, with an alloy frame featuring internal cable routing and an alloy fork. The front and rear derailleurs are Shimano Sora (Shimano's road groupset tier above Claris), paired with SunRace 2x9-speed shifters, offering straightforward shifting with lower maintenance costs than electronic or higher-tier groupsets, which suits riders who are still getting used to shifting on a road bike. Braking comes from SunRace's integrated hydraulic disc brake levers, which combine the hydraulic system directly into the shift lever rather than routing a separate brake cable, giving more consistent stopping power than traditional rim brakes with one less cable to maintain.

Specifications source: Camp official product page (campbicycle.com) Radon X, cross-checked against supplier spec sheet. Hub bearing count, rim depth and tyre width can vary between production batches (Camp's own official page states "components may vary by production batch — actual product prevails"); please contact us before ordering to confirm the current configuration.

 

Size Selection Guide

The table below is the supplier's recommended height guide, for reference only. If you're between two sizes, please contact us before ordering, or book a Jollymap Bike Fit to confirm.

Frame size	Recommended height
460mm	160–173 cm
490mm	172–178 cm
520mm	176–183 cm
540mm	183–190 cm

Height ranges are the supplier's own reference recommendation, not a guarantee of fit — riders with longer or shorter limbs relative to height may suit a different size.

 

Camp Road Bikes Compared: Which One to Choose?

Here is how the two Camp aluminium road bikes compare by frame, groupset and wheelset:

Want a higher-tier groupset (Shimano Tiagra with a power meter)? See the same brand's Camp SR5 Sport Tiagra with Powermeter Aluminum Road Bike (2 × 10-speed Shimano Tiagra 4700 with a Magene SPX1 power meter crankset). Want to compare entry/mid-tier road bikes from another brand? See the HASA Coraggio 2025 105 (Shimano 105 groupset, carbon frame).

FAQ

How much does the Camp Radon X weigh?

Camp hasn't published a weight for this batch. Actual weight varies by size, colour and fitted accessories — contact us before ordering if you need an exact figure.

What size should I get?

Use the supplier's recommended height guide above as a starting point (for example, 172–178cm for 490mm). Because saddle height, arm length and flexibility all affect fit, please contact us before ordering if you're between two sizes, or book a Jollymap Bike Fit.

Is Shimano Sora suitable for a beginner?

Yes. This bike's front and rear derailleurs are Shimano Sora, which shift accurately and reliably. The shifters are SunRace integrated hydraulic disc levers, and the operation may not feel exactly the same as Shimano shifters — feel free to contact us before ordering if you'd like to know more.

What does "integrated hydraulic disc brake lever" mean?

It means the hydraulic braking system is built directly into the shift lever, rather than a cable-actuated ("mechanical") disc brake where the lever pulls a cable to the caliper. Hydraulic fluid transmits braking force through a hose, giving more linear, consistent stopping power and one less exposed cable to maintain.

How do disc brakes hold up in Hong Kong's hot, humid weather?

Hydraulic disc brakes give more consistent stopping power in sudden rain than rim brakes, which suits Hong Kong's summer weather. We recommend a periodic brake fluid and pad check, particularly if you're riding long descents regularly.

Can this bike's groupset be upgraded later?

The frame and fork use common road bike standards, so upgrading the groupset or wheels is possible in principle, but actual compatibility (brake calliper standard, shift cable routing) should be confirmed with us before ordering or before any upgrade, to avoid buying the wrong parts.

Where is Camp made, and is it a reliable brand?

Camp is a bicycle brand manufactured in Huizhou, Guangdong, China. As an entry-level brand, it uses mainstream component suppliers like Shimano for key parts (this bike's Shimano Sora derailleurs), which gives a reasonable baseline of mechanical reliability.
