Well, Slippery Jim, I suggest you start by getting Angelina to apply a little light massage (but
don't let it get out of hand) and lay off the cigars and booze a bit :-)

2) see a sports physio if it persists
3) check saddle height; is it too low ?
Quoted message said:I've raised the saddle 3 times over the last few weeks. I'm fairly sure I tend to ride with the
saddle quite high, principally because I don't think my thighs get sufficient exercise if it's
not high enough to stretch my leg. Just a personal thing, but maybe my knees are now getting
greater stretch.
Pain in the front of the knees, or under the kneecaps, /can/ be due to various disorders, but AFAICT
is much more usually down to adjustment or cadence. Having adjusted the saddle three times recently
may just mean that it was further out than you think :-) I am 6'1" tall and the top of my saddle is
about 44" off the ground on my tourer - it looks a long way up (and feels it when I climb up there
from my recumbent).
As you may know the usual starting point for saddle height is 109% of inside leg length (crotch to
floor, no shoes) from the bottom pedal spindle to the top of the saddle [(c) Richard Ballantine].
You can refine this by trial and error, tweaking in small increments (1/8" at a time or less), or
get a more accurate fitting from your bike shop or at wrenchscience.comwrenchscience.comOpen ↗. If the saddle is
too high your hips will rock from side to side when pedalling, and you will tend to get pain in the
calves and the backs of the knees. If it's too low you will suffer discomfort in the front of the
knees. This much is well known.
Quoted message said:Quoted message said:4) check pedalling speed; do you slog around slowly, or spin quickly ? Should spin at >60rpm,
possibly >90rpm, including uphill, that's what the "granny" gears are for.
Quoted message said:I used to be slow spinning (obviously requiring greater effort) but recently I've dropped a gear or
two to spin quicker. I'll either stick with that or spin higher if anything.
The Cateye Astrale seems to be very cheap these days and comes with a cadence function. I find that
a sustained cadence of much below 90rpm causes knee pain.
Quoted message said:Quoted message said:6) if using clipped pedals (SPD etc), check the position of the cleat, amount of float, etc.
Quoted message said:Interesting that you mention that, but when I was cycling a couple of years back I had exactly
the same problem with toe clips. Hopefully that eliminates SPD from the equation (which I am
using now).
Not necessarily. I found that I suffered some discomfort at the outsides of the knees when I had
SPDs adjusted for high tension and the cleats were aligned with the heels too far out. Moving the
cleats to put the heels slightly closer together, and the cleat nearer the heel, improved this. But
that was on a recumbent, so may not hold for a wedgie.
