Volagi Vijae with Continental Speed CX tires.
I have logged quite a few rides on roads and trails with this setup. The Continental Speed tires are a really good all round tire. I did a fast paced group ride over Mount Hamilton with this setup and didn’t really feel as if they were holding me back. The disk brake setup on the descent of Hamilton was as good as I hoped it would be and the fat tires and compliant frame made even the miserably bumpy San Antonio valley road tolerable. I am still not sure if I would use them on a full double century as they have to be slower than road tires but I am considering it.
Continental have some new tires that I am hoping will be on sale before the Devil Mountain Double. A dream tire ? 700x28c.
