Been riding my (first) road bike for about a year now, and when I bought it, the guy at the LBS just kinda eyeballed my seat height as I sat on it (heck I wasn't even wearing cycling clothes). Well, I've been comfortable all this time, but for some reason out of the blue about 2 weeks ago, I started getting some knee pain on the front right side of my left knee(y'know, in that little pocket of muscle/tissue on the inside of the knee cap). FWIW, I ride platform pedals(VT Gripsters), with straps (Hold Fast)--not going clipless (yet).

So as I say, all of a sudden, my knee gets to hurting, though I haven't changed a thing.

I started reading more about saddle height and from what I can deduce, my saddle was a good 2.5 inches too low(that's quite a lot, no?). I base this on the "109% theory" I've read about, plus just the plain old putting one's heel on the pedal at full extension with the pedal all the way down, etc. etc. I can't really afford a pro fitting right now, BTW, but will get one at some point (probably when I make the switch to clipless, which is inevitable, but also out of the budget right now). Anyhow, everything I read seems to suggest that saddle height being too low is the first thing to check for front of knee discomfort.

I raised my seat tonight and will ride tomorrow and see how it goes. Just thought it was weird how I've been comfy up until now, and then all of a sudden--knee pain, with nothing being changed. I suppose it's good in a way, as it lead me to check out my saddle height more thoroughly
