sorry... again, am not sure if this should be here. but i guess this is related to the frame and fork am using. anyways, i noticed a little pain in both my knees. i think it began when i started using cleats. i only do 30+ minute rounds in the UP oval during weekends. the pain isn't that much to get me real worried though. anyhow... last night i was just strolling around a neighboring village w/ my son's MTB. it's basically an AM/FR setup w/ a 16" GT Avalanche, 100mm RST fork, 70mm stem, riser bar rolling on 2.1" velociraptors. the seat of course is set very low since my son is only 11yo and bout 5'3". funny thing bout it... after bout 20mins. of continuous biking i was fine. actually, i somewhat like the avalanche so much i sort of make excuses in using it rather than my marin. ;D anyways... my wife who was with me at that time asked if she could use the avalanche so i had no choice but to take out my own rig. after about 5mins. there it is again!  hmmmm... made me think then.  my own baby is a 19" XC marin indian fire trail coupled w/ an 80mm SID Team, straight bar, 100mm stem and 1.95" kenda kozmiklites. the seat height is set up based on what i gathered from friends and fellow bikers. bar grips are bout 1" to 1½" higher than the seat... and i stand 5'11". i have problems with 2 disks in my spine that's why my bars are higher than my seat (can't bend over for long periods... or else pain will kill me). below is a pic of what my bike looks like now.  can someone tell me what's wrong? thanks. john |

most likely cleat positioning. you'll have to experiment a bit with that until the pain goes away. start with centering it below the ball of your foot.

Maybe saddle should be move forward 10-13mm. I also experience this knee pain i think when pedaling knee should be vertically in-line with the cleats at 3 o'clock. maybe.

i also had the same problem. when i got new spd shoes and put in the cleats, i biked to work and did a couple of rounds in MOA. the following day, my knees hurt. initially i thought i need to lose weight.
anyway, i noticed that my knees hurt only after i ride my bike. i didn't feel 100% while clipped in, like something's off. i tweaked my cleats a little, and bingo, 3 days later, no more pain. i could even jog/run without problems.
initially i was considering getting a Spez BG shoe. according to their site, they keep your feet, knee and hip aligned. but....i didn't need it that far, he he he.
btw, check your pedal for float, if it allows a level of play (foot placement) while your clipped in.

What the other members had said are correct.
I had the same problem before. It can either be the saddle or cleat position.
For my case I just adjusted my saddle forward until my knees are in line vertically
with the center of my pedal while it is in the 3 '0 clock position.
Since I started using clipless, I already have positioned the cleats inline with the ball of my foot.
So, I guess you have to start with cleats position then adjust the saddle.
HTH.

thanks for all the inputs. my seatpost right now is a 0º SB FSA FR220. right now the saddle is set a bit to the front since am trying to somewhat limit the angle my back would be in when am holding on to the bars. i was also thinking of changing my stem to a shorter one (currently 100mm). anyways, all points well taken. i'll do minute adjustments on saddle height (probably ½ in.), cleat position and all when am doing rounds in UP this weekend. i'll try to post whatever improvements i happen to stumble on to. i hope i don't make it worse though. thanks a mill, everyone.  |

btw, if it helps. i looked at my feet when i was running and made a mental note of the position. for some reason, i can tolerate my right foot being almost parallel to the frame. and my left foot pointing just a little bit outwards, around 2-5 degrees away from the frame.

last night i adjusted my saddle bout ½in. down and slid it back bout 1 notch based on the my dabomb velo seat. i also adjusted my cleats... now it's in the middle of the slots. did 20mins. after that w/ my son. i noted a little improvement on my knees... it hurt still but not during biking, but rather after. i made note of my kneecaps and pedals and i think my knees are still ahead about 1" of the pedals. noticed some stress on my arms since my stance is a bit more aggressive now... my back i think the rounds i did was too short, and pace is not consistent enough to make a good assessment if i was hurting it already. i lowered the saddle again another ½in. but i wasn't able to test it anymore since it was already past 11pm so i'll continue on tomorrow am when doing rounds in UP. god! i didn't realize that my saddle was a bit too high since i barely noticed any difference. i think i have to replace my seatpost w/ a new one.... probably one with 20º to 25º setback since my saddle is practically at the very end of rails. anyways, good reason to buy that CF SL-K seatpost i saw at jane's LBS. hehehe. would changing the stem to a shorter (from 100 to80mm) help? thanks again boss... and keep pedalling.  |

you should have yourself bike fitted with toots. look up the thread for bike fitting in PinoyMTBiker. last night i adjusted my saddle bout ½in. down and slid it back bout 1 notch based on the my dabomb velo seat. i also adjusted my cleats... now it's in the middle of the slots. did 20mins. after that w/ my son. i noted a little improvement on my knees... it hurt still but not during biking, but rather after. i made note of my kneecaps and pedals and i think my knees are still ahead about 1" of the pedals. noticed some stress on my arms since my stance is a bit more aggressive now... my back i think the rounds i did was too short, and pace is not consistent enough to make a good assessment if i was hurting it already. i lowered the saddle again another ½in. but i wasn't able to test it anymore since it was already past 11pm so i'll continue on tomorrow am when doing rounds in UP. god! i didn't realize that my saddle was a bit too high since i barely noticed any difference. i think i have to replace my seatpost w/ a new one.... probably one with 20º to 25º setback since my saddle is practically at the very end of rails. anyways, good reason to buy that CF SL-K seatpost i saw at jane's LBS. hehehe. would changing the stem to a shorter (from 100 to80mm) help? thanks again boss... and keep pedalling. |

it can be a lot off things. make sure you do some stretching as well before riding. i too felt some kind of pain in my left knee.parang ugat na naipit as they call it.bugged me for a week or two. did stretching before and after riding and its now gone.

i have problems with 2 disks in my spine that's why my bars are higher than my seat (can't bend over for long periods... or else pain will kill me). <snippeth the photo> can someone tell me what's wrong? thanks. john John, this might not be what bikers love to hear but here goes... Did you have an MRI taken? What's with the spine issue? |

john, how are your knees now? hope you got the proper adjustments already.
I experienced the same knee problem but not when I'm biking. I'm having the same problem when I run for about 3kms up. Let your knees recover first before you do another test to see the adjustments that you have made. Once your knees hurt it will continue to hurt even with correct adjustments already.
I experienced discomforts also before I finally got the right adjustments for my bike. With the knees, the saddle and cleat adjustments are critical. For your spine, a more upright posture is necessary. Making your stem shorter and higher will definitely do the trick. However, having an upright position will give you a hard time during steep climbs. I guess this wont be an issue since you often take rounds in UP only.
Try taking glucosamine chondroitin also. Our company doctor who happens to be a PBA doctor recommended this. It will sort of lubricate you knees and help develop the padding your knees need. It worked for me. Although, i try to avoid running already. I'm too afraid not to be able to bike because of too much running.

Did you have an MRI taken? What's with the spine issue? sorry for the late reply... super busy. anyway... MRI, yes. 12 therapy sessions... then 6-mos. wearing a brace for the lower back. two discs if i remember right. one a bit bad than the other. caused by a toy landcruiser rear-ending the toy starlet i was driving way back in '95. a yr and a half, i experienced pain in the lower back. doctors first thought it was kidneys... lumbo-sacral x-ray showed a chip in one of my vertebrae (L2 if memory serves)... and my spine straightened from the waist up to mid torso. never ever felt it wasn't there since then.  |
