The question has been asked if the fork could be left out of the order - the answer is of course yes. I don't have a word on that but based on my previous order, it would make about $150 of difference.
Geometry-wise, there is a 12mm difference to the Ti Swift compared to the aluminium one - the fork is 12mm shorter, and correspondingly the seat tube also.
For those wondering about the tyres, the frame can accommodate the biggest tyres available - 50mm Big Apples in 406mm, and at least 32mm in 451mm.
