View Full Version : pedals and knees

I didn't bother searching cuz I think I have a unique problem. Hopefully not so unique that I'm screwed. So, please offer opinions...

I started with SPDs, but switched to Look thinking that the bigger surface area would relieve the burning, numbness and cramping, especially on extended climbs. And they did... while I still get discomfort, it's a significant improvement.

Now my right knee -- injured ~5 yrs ago -- is bothering me during and after each ride longer than ~40 miles. This is more noticeable (obviously) when I'm not taking ibuprofen. I've read/heard that more float (eg. Frogs) are better for knees.

(here's the potentially unique part) my SPDs had a fair amount of float and I did experience less knee issues with them, BUT i popped my knee with 'em twice! What I mean by "pop" is it seems that if the bones above and below my knee don't line up just right, that the knee cap gets twisted up and "pops" back into place during the rotation. It happens when I hike too, tho trekking poles have really helped... I simply never take a "rest step" while hiking. Ugh.

The potentially unique issue is, I absolutely believe that the extra float allowed my bones to get twisted and then pop my knee.

I've become more conscious of my rotation and I'm trying to develop a better stroke, but it only takes one moment of distraction during a multiple hour ride for this to potentially happen. I simply cannot maintain that focus 100% of the time on every ride.

I can't afford to see a doctor, my medical plan is very limited and the economy kicked me in the 'nads. I did see a doctor years ago when I originally got injured.

So, my questions...

1. Have you heard of extra float being a problem before? (I feel more confident with less float, I think).

2. Is there a pedal I should try?

3. Is there someway to make my stroke better and more consistent?

As for the rest of my bike, while I've made the adjustments myself, I feel I've gotten as good a fit as I can without spending the money I don't have on a pro-fitting. I'm fairly comfortable even after four or five hours.

Thanks in advance!

I cannot comment about pedals float etc as you probably have way more experience in the matter. I just want to comment about you seeing a physician. Too many times people get their priorities slightly out of wack. You say you can spend a couple of hundred bucks on pedal/shoe combinations but cannot pay to see a good doctor? I'm not buying it. Doesn't take a genious to see there IS something wrong with your knee. I would take care of it so that you can bike for years into your future.

Please don't take offense at my comments, they are not intended to be malicious. Good luck.

1. Yes. Check out this recent thread on the Serotta forum: http://www.serotta.com/forum/showthread.php?t=3771&highlight=float

2. One of the guys in the forum reports using a speedplay on one foot, Look on another. Check out that thread...

3. That's concentration... Always concentrate when you're riding: on the road, on your technique, on pedalling, on cadence, everything. "Real" cycling can take up a lot of mindspace.


good luck!

No offense taken, but come on... $200 for a doctor? That $200 is only for a consultation. I've seen lots of doctors about lots of stuff and it always lead to: don't do what you're doing -or- spend thousands on whatever they think should be done.

But I don't want to turn this thread into a doctor or Opie bashing session, so thanks for your comments, but focus on pedals and knees :)

Thanks for the link. Fascinating. A lot more people like less/no float than I had guessed.

oh, just another 2 cents, i ride with no/less float, the standard shimano/shimano-clone SPD with 4 degrees of float, no problems. the only knee related issues i had were in the beginning when my saddle was too low...

btw, canada has free doctors! :p

Free doctors and when you go to see a doctor for say, something like chest discomfort or an abnormal ekg and they refer you for a cardiac study. You can expect to wait more than 6 months to get your test done vs. 1 day here in america.
:p

Sorry couldn't resist
