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?
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.
