If you're not folding often, go for it, but I predict you will be changing the headset, fork, BB, crank, and pedals in addition to the bars. If the same "quality" level obtains in the 07 Cadenza compared to the '06 Cadenza, the headset and BB are loose bearing Chinese grade Z. The BB has a plastic cup on the L side. And wait 'til you hit a road full of bad expansion joints and tar snakes... you'll dial PB or NB from your mobile phone as soon as your hand function returns to order a Cane Creek headset and a CF fork.
Has anyone on the forum rebuilt an 07 Cadenza?
