    SON20R / SONdelux for narrow forks?

    I'm looking into getting a SON-hub-based lighting system for my Brompton. While I know the SONXS is available in a narrow-axle version, I'm wondering if the SONdelux can also be had with a 74mm axle. I've been looking around online, but haven't found anything definitive yet.

    Does anybody have any first-hand experience one way or another with "narrow" SONdelux wheels?

    TIA,

    Thanks for the link. What the pic shows is actually a SON XS, not the SON 20R (a.k.a. SONdelux). The SONdelux has a hub body that "wraps around" the internal dynamo widgetry, in order to save weight.


    According to Peter White (who I am not affiliated with, BTW), the SONdelux has a weight of 390 g, versus 570 g for the regular SON20, and is suitable for both 16" and 20" wheels. No word on axle lengths, though.

    Looking at Son's website, it appears that only the SONXS is built with the narrow 74mm axle. http://www.nabendynamo.de/produkte/dynamos.html
