I will be riding with my husband who will (obviously) be on a bigger bike. Does a smaller frame mean I have to work harder to ride the same speed he does?

I'm so confused. I really liked the smaller frame but don't want to be left in the dust.
Actually no, it means that you'll have to carry less frame weight, so you can go faster! And of course, the more comfortable you feel on your bike, the harder and longer you'll be able to ride.

Your 43cm frame came with 650c wheels, correct? They're smaller than your husband's 700c wheels (which is what most people use) so make sure you always carry your own saddle bag with a 650c spare tube. If you get a flat, his 700c tube won't fit your 650c tire.

Happy riding,
