Shutter Precision PV-8 Dynamo Hub — Specs & Analysis
Manufacturer specifications, compared against every other electronics & power in our database. We do not test gear in the field — we measure, verify, and compare.
Shutter Precision's PV-8 offers dynamo hub performance approaching the SON at half the price. The machined aluminum shell houses quality bearings with impressively low drag. For riders who want dynamo charging without the premium price, the PV-8 is the go-to recommendation.
Who Is the Shutter Precision PV-8 Dynamo Hub Best For?
Value-oriented tourers who want dynamo power without paying SON prices. If that describes your riding style, the PV-8 Dynamo Hub should be at the top of your shortlist. It sits in the Electronics & Power category alongside 12 other products we track.
How It Compares
At 340g and $150, the PV-8 Dynamo Hub is 297g heavier than the lightest option in this category (the Sinewave Cycles Reactor USB Dynamo Charger at 43g). The most budget-friendly option is the Voltaic Systems Arc 10W Solar Panel at $25.
The price-to-weight ratio comes in at $44 per 100g — a premium price point, but you're paying for quality, materials, and design that justify the investment for serious bikepackers.
What We Like
- +Half the price of premium dynamo hubs
- +Low drag for the price point
- +Lighter than most competitors
- +Reliable sealed bearing design
Watch Out For
- −Drag slightly higher than SON hubs
- −Less proven long-term durability
- −Fewer spoke hole options available
The Bottom Line
We haven't scored the Shutter Precision PV-8 Dynamo Hub, and neither has anyone else we can cite. It's here for its verified specifications and dimensions, which is what the fit tools run on — a score is an editorial judgement, and we don't hand one out until someone has a basis for it. What this page can tell you is measured: 340g, $150, and how both sit against every other electronics & power product we track.
The price and weight above have not yet been checked against the manufacturer's own page. We are working through the catalogue and saying so as we go, rather than letting silence imply otherwise.
Specifications and dimensions come from the sources listed above. Where a page draws on first-hand riding, it says so.
How it compares
Against the 13 electronics & power products we hold published specs for.
At 340g the PV-8 Dynamo Hub is lighter than 3 of 12 alternatives we track. The category median is 195g.
At $150 it undercuts 2 of 12 of them, against a median of $60. That works out at $44 per 100g — above the $40 median for electronics & power products.
Weight and price come from published specifications. Cost per 100g is a blunt measure — it rewards light gear and says nothing about durability or whether the thing works — so treat it as one input, not a verdict.
