just finished building up my first fixer, LOVE it! also wicked to hear that fugazi, minor threat fans are riding around on fixies,wondered where you lot got to, good stuff
ive been road riding for a few years and this has really got me into all my bikes again. knees are on fire after first few rides but i guess they're adjusting.
any reasurance this is normal? although i will carry on anyway so dont say stop riding!
cheers tom

it could be that your seat is to high or to low or even to far forward or backward. where does your knee hurt? above the knee joint, on the knee cap, or behind the knee on the tendons?answering that can tell what you need to adjust.as it may take a week or two to work out where you need to be to ride comfortablely. also did you use the search function ? Im sure that there are alot of previous posts about knee problems and frame fit on here.

if you're mashing hard you can get tendinitis, it happened to me when I first got into cycling and didn't know about spinning and all that.

Maybe ice your knees and lower your gear ratio

what is your gear ratio. You probably just have the seatpost too low/high. Knees should have ~5 degree bend when leg is fully extended.

maybe the kind of bars that you have... i know that if i run track drops on the street, my knees kill me after a few hours, so i now run bullhorns (nitto rb-021 to be exact) and i have no problems at all with them

i am in the us and i never have knee problems...
ergo,
it is because you are british.

I would put them in water.
Third-degree burns are no joke.

All I have to say is be careful, and see a doctor if the pain gets worse.

I just got back on a bike after being unable to ride or even walk for a month due to knee injuries from riding.

Do you have a brake on your bike?

torn cartilage ftw!

no srsly, if is really bad, you may want to get it checked out. you could mount your seat on bullhorns and use 2 brake levers, and it won't cure a medical problem.

if it is fit, like they say, it might fix it. but if you know a bit about road bikes from before, i bet you are familiar with fit.

don't mess with your knees if it keeps up. trust me. i have torn cartilage in my left knee and am procrastinating on arthoscopic surgery.

Go see a psysiotherapist.

Icing helps a great deal in helping to heal knee tissue, but you need to get the timing right for max effectiveness. I think my doctor recommended 20 minutes on, 30 minutes off, pref with knees elevated, for as many repetitions as you'd like. Was a huge help for me when I had knee issues.

thanks all. my gear is 42-16 and i've copied the set up on my road bike as close as possible, the fixie's very comfortable except when slowing down so i think braking with my legs is causing the knee problem. i do have a front brake and use clipless shoes and pedals. i guess i'll just take it easier for a bit on that bike . the knees are much better after just riding my usual bike.cheers!

It's not pain from behind your knees, is it? Cause that would be strained hamstrings.

In any case, rather than slowing with your legs you might want to use skids instead, until your hammies are stronger.

Rely on the brake more, your knees will thank you.

If by 5 you mean 30...


Also watch out for people guessing when they're giving you advice on the internet. Among some of these suggestions, also stand out of the saddle when you're climbing--your knees were not built to pull up (think about it) so sitting and mashing in the pedals is going to basically pull your legs apart.
