Road.cc’s review of the HJC Bellus 2 finds it comfortable, well ventilated and solidly finished, with a revised fit system and a magnetic buckle. The review says the helmet’s SLID rotational impact system lacks published internal or independent testing details, leaving its performance difficult to assess from the available information.

Road.cc has reviewed the HJC Bellus 2, an updated cycling helmet priced at £159.99, finding it comfortable and well ventilated while saying the evidence available about its proprietary SLID impact system is limited. The review describes changes to the helmet’s fit system and notes that HJC does not provide details of internal or independent testing for SLID.

The Bellus 2 replaces the original Bellus, which came out a few years earlier. Its most notable change, according to road.cc, is the removal of the SELFIT automatic fitting system. The new version uses a conventional retention band and adjustment dial, with a height-adjustable cradle. The reviewer said the straps were easy to adjust and that the helmet felt comfortable after a short period of fitting.

The helmet also has a FIDLOCK magnetic buckle, which the review found easy to operate with gloved fingers. Road.cc described the buckle as secure and a premium-feeling feature. The helmet weighed 274 grams in the tested configuration. Its shell extends beneath the brim to cover the expanded foam, and the reviewer found its construction neatly finished.

Road.cc reported that the Bellus 2 stayed comfortable during testing that included UK heatwaves. The helmet has substantial ventilation channels, eyewear docking holes, a spare set of pads and a stick-on peak. The review lists its price as £159.99 and names six additional colour options beyond the tested version.

The developmentRoad.cc published a review of the HJC Bellus 2, assessing its comfort, fit, ventilation, construction and SLID impact system.

Comfort Comes With a Testing Question

The review presents the Bellus 2 as a mid-priced option for riders who value comfort, ventilation and finish. At £159.99, it costs more than some helmets with Mips, a more established rotational-impact system, and more than the £119.99 Lazer Sphere Kineticore cited by road.cc as a competitor. The review also notes that the Bellus 2 is lighter than some alternatives, though it is not exceptionally light.

The central consideration for buyers is the evidence behind SLID. HJC describes the system as addressing rotational and linear impacts, using gel elements intended to allow movement between the head and helmet shell. Road.cc observed that the six raised elements compress and stretch when pressed, but that demonstration does not establish how the system performs in a crash. The reviewer said the manufacturer supplied no information about internal or independent testing, making that performance hard for readers to compare with systems whose testing has been externally assessed.

How the Bellus Changed

The Bellus 2 is an update to HJC’s earlier Bellus. In the road.cc review, the revised fit arrangement is a practical change: the original model’s SELFIT self-adjusting mechanism has been replaced by a dial and retention band. The reviewer said the conventional system was quick to use and allowed the cradle to sit comfortably under the back of the head.

The Bellus 2’s SLID system is positioned by HJC as an alternative approach to managing impact forces. The source describes six gel elements on the crown of the helmet, between its ventilation channels. Road.cc says these elements permit some movement between the head and shell, although the shell’s fit and brim limit that movement. In normal use, the reviewer found the elements functioned as padding.

For price comparisons, road.cc cites the Lazer Sphere Kineticore at £119.99 and the Met Trenta Mips at £229.99. The review says the Met is lighter at 260 grams and has a well-established Mips system whose performance has been assessed by external laboratories. These are comparisons made in the review, not a complete survey of available helmets or current retail prices.

“After two minutes’ fiddling, the HJC is very comfortable.”

— Road.cc reviewer

What Testing Details Are Missing

The source does not establish how SLID performs in impact tests or identify independent test results for the system. HJC’s description of its intended function is a manufacturer claim; the reviewer’s observation that the gel elements move when pressed is not evidence of crash performance. The available material also does not specify which safety standards the helmet passes.

The review is one tester’s assessment of fit, comfort and ventilation. The author said the medium fit comfortably but was near the upper end of the size range and could have chosen a larger size, possibly with more airflow. The source does not provide long-term durability results, broader rider feedback or a full account of testing conditions.

Check Fit and Safety Information

Readers considering the Bellus 2 can compare its listed £159.99 price, weight, fit features and ventilation with alternatives, while checking the manufacturer’s current sizing, product specifications and safety information. The road.cc review does not report a forthcoming test release or other scheduled product milestone.

HJC has not, in the source material, supplied further testing details for SLID. Until such information is available, the review’s assessment of the system remains limited to the manufacturer’s description and the reviewer’s physical inspection of its gel elements.
