Description
Due to the weight reason and higher side stiffness we had been coming out with the 2nd generation of carbon frames and we stay with this one also for a model year 2012 and will be used for models CA55/66/66Di2/77/ and CA88. The reason to stay is that we are absolutely satisfied.The prime property of carbon is the absorption of roughness, shocks, but naturally, also lower weight and the chance to arbitrarily shape all tube profiles. Another advantage of carbon material is it's high stiffness, strength and lower extent of the fatigue compare to duralumin. The high comfort rate is secured by the CARBON FLEX STAY DESIGN of the seat stay, which has even smaller cross section since 2010. Novelty is also using the UD (Uni Directional) carbon outlook layer, so no more 3K woven. Application of the stainless steel stickers on the chain stay to protect the frame tubes from chain's falling of the chainwheels is already a standard. Proof of perfect geometry, choice of good material, shape of the tubes and very nice design is absolute satisfaction of the road Team PSK Whirlpool-AUTHOR with model CA 7700.| Frame | CA88, CA77 (*t 1,5“) | |||||||||
