I've seen a few, they're very nice bikes. They like to use smaller wheels (26", 650B) for smaller frames and larger (700C) wheels for larger frames, which makes a lot of sense to me although I wish 650B tires and rims were a little more widely available. I've been very happy with my own Riv tourer for the last few years. Very comfy for long rides and it's served me well on the loaded tours I've done. I ended up adding a chain peg on the seat stay, a fender boss on the chainstay bridge and a vertical fender boss on the seatstay bridge when I had the bike repainted, hopefully Grant Peterson has started including those items on newer bikes (mine was delivered in 2001).
The various canvas bags that Rivendell offers (Baggins, Nigel Smythe) are very, very nicely made and well thought out.
