So, did you get the Secula? I use PD-8/Luxos U/B&M Toplight Line Break and PV-8/Luxos U/Spanninga Pixeo Xs combos.
I'm wondering if the Secula is worth upgrading the Pixeo.
I have got two of them but as yet not in operation. My first attempt at learning wheel building skills didn't quite go to plan and I am in the process now of my second attempt. That in combination of being off the bike for some weeks including time out of the shed has delayed progress.
