I like the tradition behind the Ambrosio, but it looks like they’re for tubs only?
Following links on thecycleclinic.co.uk brought me to the Velocity Quill, which is cheaper than the HED Belgium and is 1mm wider internal (21mm vs. 20mm) and 1mm deeper (26mm instead of 25mm) and I think is the widest I’ve seen for a rim brake aluminium road rim…
Pacenti Forza is cheaper and still relatively wide (20mm internal) and the Kinlin 26T is cheaper still but another 1mm narrower internal width (19mm).
All good choices! Just depends how spendy I want to go. I have a strange attachment to my Charge. which is effectively a cheap, garish singlespeed, and feel like if I spent money in the right places I could turn it into something much more versatile… tempting.
