So someone had asked if I was worried about wrecking with the laptop in the pannier. I said I was a bit, hence the reason I got the pannier I did. Well, after riding with the pannier for the first time, I will say this: This damn thing is so freaking sturdy, so well designed, that the only way something would happen to the laptop is if I got hit by a car, at which point the laptop would not really be a concern. The mounting system is amazing as well, so it doesn't budge, even if I catch some air (it has been known to happen). Overall, I'm very pleased with it. Now, since I just got them, I decided to bring a bunch of stuff, just in case. Of course, I realized after I got back home that a second base layer isn't necessary, and while packing I added a full additional set of clothing by mistake. I also had my regular change of clothing, my booties, and my arm warmers. I forgot my hat, so I wound up wearing the balaclava, just to cover my ears.
Well, as I said, the ride in was fine. However, it was 63°F on the way home, and with an additional base layer put in the pack, I didn't have room for the jacket. I was sweating my ass off on the ride home. It was warm to begin with, and then to start actually working...wow. Also, having just about 20lbs of gear (like I said, I carry a fair amount of technology for my job, and obviously suck at picking the required stuff to bring along), and moving it from my back to the left pannier, really changed the way the bike handled. I need to increase the PSI in my back tire for sure, and just be aware that it makes the entire bike heavier. The one benefit (and it's totally not worth it) to a backpack for me is the ability to adjust the center of gravity, especially on the one big hill I have. The legs were working harder than usual. Overall though, with the exception of some longer tights/bike shorts, I can't think of any other conditions that would prevent me from biking (besides time). Yay!!
