I'm taking the Friday (Pocket Rocket) on a charity ride from Vancouver to Seattle this summer, which is something like 80 miles a day over two days. I did a century on the Friday a couple of years ago, so I know it works, but this will be the first time I've ridden this much on the Friday over two straight days (I was so wiped after the century that I didn't ride at all the next day.) The Friday is a wonderful bike, but it's heavier than the average road bike, so it takes a notch or two more energy to ride.
On my Big Bike, with a ride like this, I try to keep Stuff to a minimum -- two water bottles and a small seat post bag for rain or cold-weather gear, on the logic that there's enough support there that I don't need more than that.
But on the Friday I tend to take things easier, with a rack and a pannier. I have a single water bottle on the frame, and a second one inside the pannier, along with snacks and extra clothes. It adds to the comfort, and it adds to the weight.
My question: does anyone have experience with several water bottles on a Friday, and with a seatpost bag, so I can leave the rack at home? Or should I just accept that I will be slower, and the ride will take longer, and take the pannier so I'm ready for anything that the West Coast can throw at me?
