Yea , so far so good with velobuild! I even asked for quick shipment and Chris went out of his way to make that happen without me paying extra. The tracking says it should be here in the next week or so.
Yea as an open mould frame I think there are a few companies that sell it. Based on the velobuild product page though, it should support up to 32cm tire but I can let you know for sure when it gets here.
