Brian S.wrote a review of Ridley Fenix Carbon Ultegra Complete Road Bike - 2015 on June 6, 2016
Familiarity: I've put it through the wringer
Purchased this bike about 4 months ago and have ridden it approximately 700 miles since that time. I spent 4+ months researching carbon frame bikes to replace my heavy-ish four-year-old Fuji Newest 1.0.
My first 30 mile ride I experienced 3 chain 'pop-off's'. Unfortunately, the chain continues to fall off if I shift from the small chainring to the large chainring if the chain is not first positioned on the cassette's very smallest ring. I never experienced this problem with my Fuji.
Other than that minor issue, I have nothing but positive praise for the Fenix. The most significant difference I have experienced from upgrading from my Fuji to my Ridley is a discernable decrease in fatigue when riding, for example, 50 miles with 2,500' of elevation gain.
Regarding the title of my review, during times when I have pushed myself hard on flat terrain I have maintained speeds between 18 and 21 mph for several miles. On my Fuji, this was not possible because it is too heavy and far less 'energy efficient' than my Ridley.
As a skier, cyclist, and mountaineer who tends to wear out gear before replacing it, I hope to spend many years riding this high-performance bike that cost less than many others in its class.
