Thanks everyone for the quick and thoughtful responses. I will definitely be
adjusting height of saddle and sliding it back a bit as a first course of
action. If that doesn't help, I wanted a plan B which might be the shorter
cranks. Stretching more is also good advice that I will pass along
I agree with everyone about fit. A standard rule of thumb I read many years
ago is "front of the knee pain, too low; behind the knee, too high". I
suspect she's bending her knees too much when she pedals.

My wife is 5'-2" and rides 165 mm cranks. You don't mention terrain but
I'm guessing not too hilly if only going 10 miles? So how is she able to
do this on the 24? She must be spinning madly. I'd take a look at how she
fits on the bike. I'm not a big fan of "fit kits" but maybe something

I'm 5'2, 55 years old, have a PBH of 75, am not an athlete, don't have
great knees, and use a 165 crank. The thing that struck me the most is
that your wife is riding exclusively on her smallest (24) chainring. I'm
wondering if this might be contributing to the knee pain she feels after 10

Will second that choice. Mark is a good guy. Bias alert - I know Mark and
consider him a friend.

Sugino also makes the Mighty Mignon, but it's a 110 double , in 140,

I hope your wife can ride pain-free without you having to spring for a
crankset. I believe that 165 should be able to work. 5'3" is not that
short.

daVinci Designs has a nice looking crank with 110/74 spider available
(i.e., you can transfer your XD2 chainrings to it). IIRC, it's made by
White Industries, and some on this list ride it. (Maybe they can chime in?)
It has crank arms from 150mm to 200mm (~$220-- but I'm not sure if I'm
