On test: Fi'zi:k Arione CX Carbon, August 25, 2008

Light and comfortable

By Paul Verkuylen

The fi’zi:k Arione CX Carbon weighs just 149grams

At first glance fi'zi:k's Arione CX Carbon saddle may look like just another attempt to shed as many grams from a saddle with scant regard for comfort, but on further inspection it is far from it.

Fi'zi:k uses a number of tricks to hit the impressive 149g actual weight, including a full carbon shell, sparser padding under the synthetic Microtex cover, and clever braided carbon rails. Yet unlike many other lightweight saddles, the Arione CX Carbon is far more than just buffer between your rear end and the seatpost.

Fi'zi:k borrows the distinctive kite shape from its proven Arione but the nose is a bit shorter and flatter while the rear half is similarly narrow. Riders who are already accustomed to the standard Arione will almost certainly find this one equally comfortable.

However, fi'zi:k replaces the Arione's standard base with the Twin Flex full multi-directional carbon shell design that was first used on the Aliante. The whole shell is surprisingly compliant (without giving up too much support) and an even more flexible section under the nose makes a huge positive impact on ride quality and comfort. In fact, most riders probably might not even notice the thinner and denser padding thanks to the cushier base.

The Twin Flex carbon shell saves a lot of weight.

Fi'zi:k also uses the Twin Flex construction for its trademark Wing Flex feature. The more pliable edges flex with each pedal stroke, supposedly for better pedaling mechanics and increased comfort. This tried and tested feature has been popular for many years, but like most saddles, you either love it or hate it; it worked great for us.

The C4 braided carbon rails keep the weight down but are also impressively resistant to overtightening thanks to their unique wrapped construction. The relatively coarse texture also prevents slippage, too. The extra large rails may not fit all post designs though, so a quick check before purchase may be required (keep in mind that some post manufacturers such as Ritchey may offer specific clamp pieces to accommodate them).

All in all, fi'zi:k has done an excellent job at shaving weight from its popular Arione without compromising comfort. The Arione CX Carbon does carry a hefty price premium though, so having an open cheque book may help, too.
