How we test

At road.cc 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.

What the road.cc scores mean

Good quality one-inch components are getting scarcer but if Woodman’s Jupiter Aheadset is anything to go by, they're not about to disappear just yet. Weighing 156g, the Jupiter will suit anyone needing a bombproof headset and I can understand its popularity amongst the single speed fraternity. The unique, inverted crown race shields super smooth needle roller bearings from dirt and road srpay while O-ring seals complete the belt and braces weather protection.

I smothered everything in marine grease when I installed the headset but even without this most riders should enjoy long service intervals. Being alloy, the cups require careful installation so use the proper tools and don’t be tempted to improvise.

An expandable bung replaces the effective but fiddly star fangled nut. Ours needed a short bedding in period but after that never once rattled loose or left the front-end feeling sloppy. Such bungs are a great idea, and essential if using a carbon steerer, although I am not wholly convinced of their superiority to aftermarket headlock type systems.

Steering from the outset felt extremely refined, far surpassing that of units turning on loose balls. It's also available in standard inch and an eighth sizing which broadens the appeal to more contemporary markets including tourists and mountain bikers; it’s a shame there’s not an inch an a quarter option as the Jupiter’s ideal for tandem applications. The choice of black or silver anodizing means it won’t clash with existing colour schemes.

Verdict

Slight weight penalty aside the Jupiter won’t disappoint anyone seeking a high quality replacement headset for older road, cyclocross and mountain bikes. A super smooth and well sealed headset ideal for bikes in hard service.

It's a very curious arrangement comprising of a large cup and seal- like a mushroom sheilding the bearings from dirt and ingress thrown up by the front wheel.

How does an inverted crown race work? I'm trying to picture it in my head but the picture is rubbish
