SON 28 is a hub dynamo unversally approved for all wheel sizes from 16" to 29". The rated output is achieved in the 700c (622)-wheel at approx. 16 km/h (SONdelux at 19 km/h). Thus, SON 28 is recommended if a lot of light is required at low speed or when either devices are to be operated or their batteries charged.

The new SON 28 is reminiscent of the SONdelux in structure and looks. In the standard version (non-disc), the flange distance is enlarged by 12 mm and the bearing distance by 10 mm as compared to the SONdelux. Disc versions are available as 6-hole and as center lock.

Compared to the SON 28 klassik (model years 2000 to 2011), the power consumption when no load applied is reduced by approx. 15% and the weight by 140g.

I recommend this product
ConsHad to make my own lead up.
ProsNot much drag
Really liking this hub. Enough power to charge iPhone SE running Strava and RWGPS as well as powering Supernova E3 Pro 2 light at an average speed of 16mph.
Great Quality - Check Clearance Carefully Though

I recommend this product
ConsDimensions mean less clearance between spokes and brake caliper than any other hub I have seen
ProsReally good quality
Schmidt Son hubs are fantastic quality, and this is the third hub I have had of theirs, with the other two still going strong after quite a few years of use.
A word of warning though - the SON 28 6-Bolt disc leaves less clearance between the brake caliper and the spokes than any other hub I have seen. I had to change from a 160mm rotor to a 180mm in order to prevent the spokes catching on the caliper. Since I have had this fork and brake combination working with at least 6 different disc hubs and this is the only one to ever have this issue, I would advise checking clearance before purchasing this hub.
Other than that I would thoroughly recommend the hub.

Ordering the correct Son
25 Feb 2021
I would like to install a SON dynamo on a Hunt 4-season disc, QR, with 28 spokes carbon wheel. Which model I should order, and could I reuse the spokes or would need an upgrade to a more robust type? Are the Supernova E3 front and tail lights compatible? Thank you.
Hi, we would never recommend reusing the same spokes- you would need to calculate the length for new ones. Supernova lights are compatible with this dynamo hub however only supernova front and rear lights will work together.

SJS built a wheel around this hub for me a few years back. Now I have a new fork. Is there any converter to make this hub usable with a boost 110 15mm thru axle fork?

Thank you
Sadly no, you cannot covert qr SON hubs to thru-axle.

Can you confirm SON 28 product that is compatible with this
12 Nov 2020
Hi I have a new Trek hardtail with the following:

FORK - Fox Performance 32 Step-Cast, Float EVOL air spring, GRIP 2-position damper, remote lockout, tapered steerer, 44 mm offset, Boost110, 15 mm Kabolt axle, 100 mm travel

WHEEL - Bontrager Kovee Elite 30, 6 bolt, Boost 110, 15mm Axle

Hi, for your forks which are Boost (110mm OLD and 15mm thru-axle) you need SJS part: 39111

Hope this helps.

Can I use this with my Genesis Croix de Fer 10 2018 ?
20 May 2019
I'm sure that my CDF has a 100 mm front fork width but thought I'd check ?

One the SON is built into a new wheel, will I need to adjust the my front brakes (TRP Spyr) to re-align with the new disk rotor as it may not be in exactly the same position as on my existing wheel ?

Lastly, as I plan to run this with a 700 x 35c tyre, would you recommend either 28 or 32 spoke holes (or perhaps there isn't much in it)? I'd prefer robustness to being light weight.
Hi there,

Yes this would be suitable for your Genesis. You will more than likely have to perform some slight adjustment to the brakes. We would recommend either 32/36h for off road / touring style riding which the CDF is designed for.

Thanks - 21/05/19
Should this come with wires? I've got some small connectors, but no cables to use!
26 Jun 2018

Thank you for your enquiry, the hubs are not supplied with any wires these will be with what ever light or device that your are going to use with it. Schmidt always supply a set of connectors so that these can be used with what ever has been selected.

Kind Regards
What comes in the box?

Does this come with any connectors? If not, which connectors would I need to wire up a Sinewave Reactor?

This product comes with a skewer and connectors.

V Brake Possibility?
14 Dec 2016

My bike is not disc brake compatible, but I am thinking of building a Rigida Andra 30 wheel around a Centre Lock or 6 Bolt Dynamo hub and use it with my current V-brake, with the prospect of switching to disc brake using the same dynamo hub in the future. is that a possibility? if yes, which one do I have to chose? centre lock or bolt?

Thank you very much.

This is definitely a good option, as it does future-proof your hub. You can choose either as the hub internals don't change simply the method of fitting the disc brake rotor to the hub. 6 bolt rotors are the more common fitting type so for the best choice of options I'd recommend going for that fitting.

Can This Dynamo Hub Use With 100Mm Width Front Fork.
30 Nov 2014
Can the Schmidt SON 28 6Bolt Disc Dynamo Front Hub Black 36H use with 100mm width front fork. Thanks You.

This hub uses the standard 100mm OLN spacing so will fit fine into your forks.
