Also, for SF or anyone, I'm curious about the tires you use on your Cervelo. Do you use 700x23? Any problems with that if you do? I ask cuz I got some info from Adventure Cycling and they rx larger volume tires -- 700x28!! -- for their tours. I imagine that that's cuz they are looking at week long (or longer) trips on a heavily weighed down touring bike. Your thoughts?
I don't do the same types of multi-day trips that you're talking about, although I'd love to change that at some point. For me, having that little thing you plug into the cigarette lighter in the car, and get a couple of USB charging ports out of, has been enough. I've camped with the bike, gone on a few rides, and been able to recharge the Garmin overnight this way.
I'm hugely interested in solar chargers, but now sure how well they work. I think some of them can sit on top of your backpack and charge their own battery, then you could fill your Garmin overnight from that? I think this one does that
; I'm not recommending it, just giving an example.
I'm using 700x23 tires, I'm not sure my bike would take 25s. I'm using Conti Grand Prix 4000S, which are wide for 23s.
Probably they suggest 28s because wider tires are definitely more comfortable. If you're going to be in the saddle day in and day out, comfort is probably more important than speed (rolling resistance, weight, and all that). That's my guess anyway.
