Can you please tell me the spoke length required to build a wheel using this hub and an Ryde Andra 30 26
Hi there,

I have had our wheel builder look at this and can confirm that the length you need is 254mm in a 3 cross pattern with 14mm nipples.

differences in dynamos

What's the differences between the various 3W Shimano hub dynamos?
Hi there,

There are many particular differences such as colour, disc brake or rim brake, finishes, bearing quality, groupset matches etc.

Can I fit security skewers to this item?
24 Jul 2017
I currently have my wheels secured with kryptonite skewers and need to know whether I can continue to use them if I fit this dynohub. Thanks

The skewer fitting is the same size as a normal hub so you ca continue to use your security skewers with this hub.
