I have a On One Inbred (DN6 Steel) SS which I love and also have a Custom Ti frame from China which is basically the same as On One 456 summer season, which I also love and it only cost the same as a good steel frame. I have also owned a Cove (litespeed) Hummer and have also ridden the latest Hummer and couldn’t really get on with both. IMO its good geometry that makes a good frame but Ti did have the edge over the steel bikes I have ridden, especially when riding at speed on rocky singletrack.
Gavin email me if you are interested in designing your own Ti frame I’ll send you the details.
