So I’ve got two rides on my bike now that it’s set-up with a front rack. First ride was front rack + saddle bag load so 2 pounds for the rack(?), 2 pounds on the front rack and 3 pounds in the rear. Steering felt a little heavy and bike was slower to respond but seemed to like the weight and pedaling felt easier and less spinny than previously. Essentially the additional weight made it feel more like a 700c bike than a 650b bike as far as pedaling was concerned.
Second ride I ditched the saddle bag and moved everything up front. 2 pounds for the rack and 3 pounds for the load. Steering feel increased a bit and responsiveness decreased a bit as well. Although really it’s sorta like the responsiveness changed instead of decreased. The bike wants to flop when turning so it requires a lot of body english and counter-steer but it can be made to respond like before, it’s just harder. I also noticed there is a lot of wheel flop during steep seated climbing. The bike wants to wander all over and when I’m really tired it takes more energy to keep tracking straight. However, this is offset by how much better the standing climbing is, which is cool because I am a great stander and a poor sitter.
What really blew me away was how much better the bike felt pedaling in all positions without the saddle bag. Who knew this would be so much of change? It seemed to plane for me in a way that it was not doing before, although I’ve only got one ride this way so it may just be bullshit. I’ll find out I guess.
