has very tight tyre clearance for a general purpose bike. it looks like 25 is the limit, perhaps a 28. It is also a bit over-geared.

The Sequoia has long reach calipers (it says), so you should be able to fit 32mm + fenders, but check first. The front wheel (28 spoke radial) looks a bit lightweight for off-road, but it may be one of those funny designs.

You wont get a 35mm cx knobbly on any of these bikes, but I ride plenty of off-road using std 32mm touring rubber. I prefer 28 for general road riding.

The Sequioa gets my vote, but for better CX/touring capability in this price range, check out Fuji and Bianchi models.
