Hi all,would appreciate some advice/info,i'm looking to upgrade my wheels from fulcrum 7's,both the Zonda's, Eurus,and Shimano get great reveiws,but are the Eurus/Dura-ace worth the extra cash?,i live in the south lakes so there's lots of climbing to be done and as most places these days blooming pot holes everywhere so they need to be robust and obviously spin forever,any info/ advice would be welcome-thank you.
