Is it true that carbon/Ti bike can't hack the trainer?(6 posts)

I'm getting fitted today at the LBS for my new Seven frame. The bike shop says to go with the Axiom (all titanium) because you can't put the Odonata (CC/Ti combination) in a fluid trainer due to the torsional/twisting loads. There were several reasons to go with the Axiom ($500 cheaper to start with) over the Odonata, but this one I would have never guessed. Anyone think this is bunk?

I would assume it's because of the "weld" between the carbon seat stay and the Ti chainstay. This could potentially be a weak point of the frame. With the fluid trainer attaching at the same spot, it could possibly fail if it wasn't allowed to move around a little bit. Now I'm no metalurgist or frame builder, so I could be totally off-base with this one.

You could always email Seven and see what they say. Their customer service department is very responsive when I've talked to them before.

Let us know what you find out.

Bunk or not, it will void the warranty. Having gotten the Odonata, I'd say save your money. The carbon rear end doesn't feel that much more comfortable to me (compared to my Bianchi aluminum frame), and muted and not lively enough.
Why would you put a bike that nice on a trainer?lonebikeroftheapocalypse

Buy the one you want and use your beater on the trainer.
Depends somewhat on the ridertreebound

Watch three people ride a bike on a trainer and focus in on the handlebars. Different people put different amounts of flex into their riding when on a trainer. I've seen some who look like they'd break a 1965 steel Schwinn on a trainer.

Just get a set of rollers and forget the trainer, or get or use an older bike on the trainer.
