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 today, 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 an enormous 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 meanwhile. In a time the place daytime operating lights will preserve me safer on the highway, GPS mapping can lead me to find new locations to trip, my smartphone is a wonderful cell digital camera to share these rides, and derailleur batteries are rapidly recharged through USB… the concept of self-sufficient energy as I pedal is at all times engaging. I’ve had each kind of digital system 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 nearly disappears behind even a small disc brake rotor, providing you with a extra trendy 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 a daily 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 permits particularly excessive energy output” so you cannot solely energy your lights but additionally recharge all your devices as soon as you might be using at a continuing velocity.
SON meant the 12mm thru-axle 6-bolt disc 29 S hub for highway or gravel wheels, with straight-pull spokes. It options radially lacing on the driveside, and 2x on the disc aspect. 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 commonplace with SON’s easy-plug coaxial connector (like proven above).
However it’s going to even be attainable to get one to work with SON’s self-connecting SL interface that integrates a powered ring immediately 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
For the reason that 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 highway or gravel.
With that stated, count on the brand new hub to even be accessible quickly to respected skilled wheelbuilders for customized builds. And with its slender design and a pair of:1 24-hole choice, we count on to see a variety of carbon highway, 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 progressive 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 ready to attract extra energy from a hub dynamo than some other charging system in the marketplace (from 700c using velocity of >30km/hr) making it excellent for the journey racer with plenty 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 in your sensible system.
