Bell Lumen Helmet



Well fitting road helmet with the emphasis upon safety but minor weight penalty may deter some

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Firmly of the tarmac tribe, the Bell Lumen sports a gently sculpted profile, that's accommodating of Gore tex covers when its biting cold and raining dogs while conforming to both EU and US safety standards. The latter might also explain why ours tipped the scales at 317g.

Quality of construction and materials are every bit what I'd expect from one of the world's biggest manufacturers, although its clear lacquer topcoat had begun receding in places. Colour scheme on ours was a timeless red, white and black tricolour that coordinated beautifully with my Univega and seems highly resistant to scuffing, swirling and similar superficial grazing. Other colour combos are available though including turquoise/silver; black/blue and white/silver.

A low-slung cradle improves stability and more significantly, is designed to protect the brain from the multiple twisting forces involved in faster terra firma tumbles. This also provides a nifty spot for small blinkies, which can be secreted out of harms' way within the centrally mounted rear vent.

You'd be forgiven for thinking inbuilt GPS was an integral guidance system but in this context the acronym refers to Bell's adjuster dial. Reminiscent of a derailleur jockey wheel, it's designed for ultra fine-tuning, say when donning a cap/buff mid ride. Easily operated in gloved hands, this is a different, as distinct from better system but gets my approval nonetheless. Machine washable anti bacterial pads continue the civilised theme, although given the twenty-two ultra efficient inlet/exhaust vents trench helmet should be something you'd need to worry about anyway.

Beautifully simple to fettle I was immediately conscious of the helmet's ergonomic fit and quickly forgot the 40g weight penalty over my regular lid. Air literally courses through the vents but without ramming the frontal lobe, explaining why I haven't suffered those agonising headaches when letting rip on extended descents in cool weather.

Its much the same story with steady cruising, cooling airflow wafts seamlessly through the scalp, retaining a temperate inner climate with only trace dampness apparent after three hours'. That said, dependant upon livery I've a feeling it may lose out to lighter competitors when temperatures climb nearer 30degrees, which may be a consideration for continental training camp devotees.

Bell Lumen is a very well engineered road helmet with higher safety accreditation than many similar designs. Undeniably competent and very comfortable worn for longer periods, additional grams will polarise opinion at this ferociously competitive price point.
