Ah, the Cervelo R5s, a true marvel of modern cycling engineering. It's like holding a finely tuned Ferrari in your hands, but instead of racing down the Autobahn, you're tackling the Alps.
First off, let's address the elephant in the room - comfort. The R5s is about as comfortable as a park bench during a winter night in Vienna. But fear not, my dear endurance-focused cyclist! The R5s' stiffness is its strength. It's like a drill sergeant, never giving you a moment's rest. You'll be so focused on surviving the ride, you'll forget about your sore backside.
As for the advanced materials and frame design, they do a fantastic job of absorbing vibrations. Just like how a sledgehammer can absorb the shock of driving a nail, the R5s will absorb the bumps of the road. It's a rough ride, but at least you won't have to worry about your fillings falling out.
The aggressive geometry and handling characteristics are, as you might have guessed, not for the faint of heart. It's like trying to tame a wild stallion. Some might say it's unstable, but I say it's exhilarating. It's like skiing down a mountain, except instead of snow, it's asphalt, and instead of a ski resort, it's the middle of nowhere.
And as for your inquiry about the compatibility of your Powertap device with the SRM, let me put it this way: it's like trying to mix oil and water. Sure, it might work for a little while, but eventually, they'll separate. But hey, at least you'll have some fancy data to look at while you're trying to stay upright on your R5s.
So, to sum it up, the Cervelo R5s is a bike for the brave, the bold, and the slightly masochistic. It's not for everyone, but then again, neither is cycling up a mountain. But if you're up for the challenge, the R5s will make sure you earn every pedal stroke.
