Only wildcard, and this is unknowable at the consumer level without seeing any test data is...and why I personally wouldn't opt for a combination frame material frame build....is what is the life of the 'connection' of the two materials? It maybe fine and no problem at all, but not common to the industry. No doubt the union of carbon and Ti is glued, so I would be curious about any stress corrosion or fatigue life issue...or loss of bonding strength due to stress over time.
This concern maybe completely unfounded but a reservation I would have.
Enjoy your new bike.
Would you expect the adhesive bonded joints to be any less secure at a carbon-titanium interface than at an aluminum-aluminum interface? Glued aluminum bikes had lots of faults back in the day, but debonding wasn't one of them as far as I know. The Trek 1000, 1200, 1400, and 2000 were all pretty reliably put together. Same for Vitus and Alan. I know that aluminum-carbon bonds were prone to electrolytic issues, but I would think the titanium-carbon interfaces would be much more inert. And even with the electrolytic issues, am I mistaken, or wasn't aluminum bonded to carbon the construction of the Trek 2300s? What's your take on this in light of the history?
