The bulbous dynamo hub is about to be a factor of the previous, due to this smooth SON 29 S hub dynamo. With all-new slender electronics inside, SON Nabendynamo tucked the dynamo generator into an enlarged flange behind the 6-bolt disc brake tabs that could possibly be simply missed. With extra efficiency all-road, gravel & journey touring bikes with ever-expanding digital devices as of late, SON is making a greater case for limitless energy on the go!
SON 29 S smooth low-profile hub dynamo
Can I simply begin out saying that I’m a giant fan of dynamo hubs. Even when I don’t put in as many kms as I’d like, on the one gravel bike I’ve arrange with a dynamo, in the mean time. In a time the place daytime operating lights will hold me safer on the street, GPS mapping can lead me to find new locations to trip, my smartphone is a wonderful cell digicam to share these rides, and derailleur batteries are shortly recharged by way of USB… the thought of self-sufficient energy as I pedal is at all times engaging. I’ve had each kind of digital machine die on a trip earlier than. However by no means on my dynamo-equipped bike.
So now SON Nabendynamo has their first new hub dynamo in a number of years.
The SON 29 S is a lower-profile hub with a brand new generator design tucked into an outsized disc-side hub flange, developed for the performance-oriented journey market. On the bike, it virtually disappears behind even a small disc brake rotor, supplying you with a extra fashionable aesthetic.
Tech particulars
The generator contained in the SON 29 S dynamo hub could also be slender, however it’s nonetheless designed to place out the identical 6V/3W energy as an everyday dynamo. Just like the 28, SON once more optimized the 29 S for energy output at comparatively low speeds and 29″ wheel – outputting 6V from round 15km/hr (StVZO-compliant). In response to SON, “along with sensible charging electronics, it allows particularly excessive energy output” so you can’t solely energy your lights but additionally recharge all your devices as soon as you’re driving at a relentless velocity.
SON meant the 12mm thru-axle 6-bolt disc 29 S hub for street or gravel wheels, with straight-pull spokes. It options radially lacing on the driveside, and 2x on the disc facet. The 29 S gives symmetric 32-hole drilling or 2:1 drilling for 24-spoke wheel builds, and comes solely in black.
The brand new dynamo comes customary with SON’s easy-plug coaxial connector (like proven above).
However it’s going to even be doable to get one to work with SON’s self-connecting SL interface that integrates a powered ring straight into the dropout (like on this purple fork that comes on Urwahn bikes). Then you definitely don’t even must unplug the dynamo to take away the entrance wheel.
SON 29 S dynamo – Pricing, choices & availability
Because the straight-pull hub design requires a bit extra experience to construct up, at first SON is just providing the brand new SON 29 S dynamo hub in wheels constructed by them now in Germany. Full entrance wheel builds begin at 550€ with an alloy DT Swiss rim for street or gravel.
With that mentioned, count on the brand new hub to even be obtainable quickly to respected skilled wheelbuilders for customized builds. And with its slender design and a couple of:1 24-hole choice, we count on to see various carbon street, all-road, and gravel wheels constructed up with the brand new SON 29 S hub dynamo in time for the beginning of subsequent yr’s journey racing season.
New Ladelux LED dynamo headlight, too
Along with the revolutionary new dynamo hub, SON additionally has a sensible new Ladelux dynamo-powered headlight, with low & excessive beams. SON designed the Ladelux for clean output USB-charging of your electronics with a small inside buffer battery. And SON claims it’s in a position to attract extra energy from a hub dynamo than every other charging machine in the marketplace (from 700c driving velocity of >30km/hr) making it excellent for the journey racer with a number of devices to maintain juiced.
The 480€ Ladelux places out 120/180Lux at any velocity, backed by a 1200mAh battery inside, and features a handlebar swap and magnetic charging cable to your sensible machine.
