Specialized, Pinarello, Cervelo, Colnago, BMC, Scott, Giant etc all have at least 4 sizes of TT bike. I think Canyon and Merida are the only WT sponsors with less.I think this would be the key. I'd guess there have to be at least 2-4 bike manufacturers that should have a TT bike that would fit him correctly and handle the way he wants it to. Just all obviously aren't going to work. Obviously BMC works well for him. I'd think both Pinarello and Specialized bikes would work as well. (I think Specialized has 4 sizes so might work).
