I’m not really a triathlete – I don’t have the knees for running – but I’m looking at the titanflex for plain old road riding here in the mountains of northern NM – no, it’s hardly flat up here, and it’s not all desert either. Ane comments on buying/using these bikes even if you’re not doing ultra or tri riding?
I can’t imagine why you wouldn’t consider one… Those are some nice bikes. If you aren’t riding ultra steep, there’s even more reason to consider one. (Note: this is not to say that a TF won’t work if ridden steep, but I doubt very much that the geometry of the bike was designed with that in mind)
I’d say go for it. My Tri bike is a softride and I got a great deal on it, but I would love to have a TF for the road, especially if the roads are rough. The frame is plenty stiff and the weight penalty is minimal. Pedalling right over the minor road bumps and the relief that your buttocks and back will feel are all great reasons to have one.
