I've done 140 km on my Thorn so far (over 5 rides) and Rowan has done about 130 km on his (over 3 rides). We've had to make a few small adjustments for comfort (for me, it was some teensy adjustments in saddle height), but once that was settled, I've been comfortable ever since, and I think Rowan has as well.

Very soon we're planning to take them out with panniers to see how they handle with a load.
