Bell Sweep



Not the lightest but nonetheless, a superbly designed lid for competitive road and trail duties

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.

Bell's Sweep helmet is refreshingly different and an excellent choice for road racers who enjoy competitive mountain biking but want a single, lid with nominal compromise. Riders expect something very special for one hundred quid, especially in the present economic climate. So how does it hold up?

Once upon a time some clever engineers invented in-mould technology where shell and EPS foam were conceived simultaneously, thus optimising strength to weight ratios, while minimising production costs. Close inspection suggests this is tidier than most, complying with CE1078 and the supposedly stricter American CPSC safety standards.

Both use the flat anvil drop test, although the latter requires an impact velocity of 6.2m/s as distinct from 5.42-5.52m/s to pass. Number of vents, rather akin to megapixels or indeed horsepower are less significant than their deployment- the sweep has twenty comprising of inlet and outlet. Integral composite skeletons aren't a completely revolutionary concept either, reinforcing the structure, presenting fewer restrictions when it comes to styling.

Fit is ultra intuitive thanks to the TAG (Twin Access Gear) system which enables optimal adjustment both circumferentially and horizontally. Coupled with the low-slung cradle, this affords an extremely stable platform, thus protecting the wearer's head from twisting impacts during a crash but can still interfere with some backpacks.

The relentless supply of cooling air has never ceased to impress, accentuating sensations of speed and freedom. Winching myself along some very steep climbs at pedestrian pace with heavily weighted trailer en tow failed to impede their efficiency either, so boiled brains are highly unlikely.

I've typically alternated between buff and race cap but forgoing these while helter-skelter descending hasn't induced 'Ice cream' headaches or that intrusive roar more endemic to trail specific models. Singletrack shenanigans were equally pleasing and despite some initial scepticism, the marginally shallower peak hasn't been any less effective at keeping stray foliage or airborne particles at bay.


Not the lightest but nonetheless, a superbly designed lid for competitive road and trail duties.
