I have been touring on my Ti Bruce Gordon RNR for over 20 years for both on and off pavement touring fully loaded including the Divide Ride. I had previously toured on dedicated steel 700C touring bikes from Mondia (Swiss) and 26in mountain bikes from Tom Ritchey and Fat Chance. The BG gives me the best in riding characteristics of these earlier rides plus the pleasure and comfort of the Ti ride. I can choose any terrain with the BG 28er tire size. The only limitation is the 700x47 tire size maximum. Only 29er bikes would give me larger tire choices with more tire volume.
The Ti tubing chosen for my bike included oversized and ovalized and others that were chosen to carry me the Clydedale and my touring load effectively. The bike has a lively ride when unloaded and when loaded the ride is dampened a bit but feels faster with the touring load. It is a pleasure to ride and looks much like new after these 20 some years. A well designed and crafted Ti bike is a joy but not everyone has the skill and training to make one. Choose your builder carefully. Good luck on your choice.
