Knee Fatigue

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

Knee Fatigue

Hi everyone,

I just finished my fixed gear bike. I'm running 42/16, so 69.5 gear inches. After riding about 1.5 miles, I feel fatigue or something in my knees and lower thigh right where it connects to the knee while riding. I am using my fixed gear to train with to make me stronger on my road bike. I just don't want it to injure me and cause me not to be able to ride my road bike. Is this a normal sensation? As I sit here and type this I can feel my knee..it isn't hurting but it feels different. I guess I was just expecting my thighs and lower legs to burn, not anything with my knees.

Thanks a lot,

-Mike

Is your setup exactly the same as your road bike(s)?

Turning big gears in the saddle puts a lot of pressure on the knees. I feel it on the outside of the knee, on the right of the right leg and on the left of the left leg. It's a warning sign for me.

If I dip below 65 rpm's in the saddle due to too big a gear, that's when I know I need to either downshift or stand. Last summer I used to get awful pains in my left knee after 40 miles on a few occasions, I still don't know what the problem was. Now, when the afforementioned situation occurs, I get a clicking sound in my knee in the 1 o'clock position.

My advice: mess around with your seat position until you feel comfortable.

I can't ride Fixed because of my knees. It's not good for my knees.

Climbing hills in too high a gear is not good on the knees and you'll feel what you felt. If your knees hurt on the outside, it could be your saddle is too high. Trying to brake by putting back pressure on the pedals will really hurt your knees; can you skid?

It could be you've just overworked the thigh muscles around the knees; you could go 42/17 or just not hammer so hard until you get used to the ride.

Thanks for the replies guys. Thing is I not really hammering it or anything. It feels good and I am not in pain, but I was just wondering if I'm doing damage. The hill I did wasn't anything to thing twice about either, can do it with ease, just I noticed my knee.

I do not skid or anything. I have a brake and use that instead. I just want to use the fixed to become stronger.

I think I know the feeling you're talking about, and I'm pretty sure it comes from using some muscles in ways you're not used to. I started riding a fixed gear to help my cadence and spin, but riding it gets heavily addictive after a while in its own right.

Anyway, as long as I don't feel pain, I don't worry too much. If I feel pain, I take it easy for a while.

Are you using the identical pedals and the same shoes as your road bike? This may be a cleat position problem.
