Clipless pedals add about two percent
I just did an experiment comparing clipless pedals to toe clips. I found about 1.9 percent improvement on a climb and 1.85 percent on a flat course. How much do clipless pedals help you?

I asked this question a few weeks ago and didn't get any replys. I know that they do increase your power output, but didn't know how much. I also read where they say to put the clips on your shoes as far back as they will go. The same if you have knee problems. In Andy Pruitt's book he recommends the clipless for more power output, but he didn't give any figures. I feel they helped me, but others say they don't.

I don't know and don't really care. I've been riding clipless for 16 years and can't stand riding a bike without.

Clipless gives you the ability (or better ability) to pull up with the off leg. You can use that motion to increase your power or to relieve your "push" muscles for a while and let the O2 catch up with the debt. The actual effect is extremely dependent on the situation, the rider, and the current gravitational constant.

- lost 40 pounds (18%)
- upped my average miles from 128 to 163 per week (27%) and 229 per week the past 4 weeks (79%)
- increased my average speed over the same 30 miles course from 14.2 to 16.6 (17%)
- dropped my resting heart rate from 56 to 48 bpm (14%)
- got off my bp meds and lowered my bp from 138 to 116 (16%)
My Egg Beaters don't deserve all the credit, obviously, but I could not have done it without them. Any one out there make that sort of progress on flat pedals or toe clips????

I know they help me when I am pedalling up hill. I use muscles that I can't use with regular pedals. After using them for a while it just doesn't feel right without them.

From a motorsports background, something that can give a 2% improvement in lap time is absolutely amazing. I have no intention of ever using clipless, but my first reaction was 2% -- wow!

The clothes don't do anything physically to add to my speed or reduce my weight or increase my riding time. But the novelty (not to mention the comfort) makes me want to just ride and ride. Besides, as long as I'm moving, I don't hear any comments about how I look in those clothes, so, I ride and ride without stopping (and I lose weight and look a little better every week!!).
I used to be almost stoic in my insistence that there was some benefit to platforms (variable foot positions, and so forth) until I actually installed them - not because I wanted to improve my performance, only because I had run out of toys to purchase for my bike, LOL.
They have improved every aspect of my riding experience.

I've been wearing bike shorts and jerseys for quite a while and now face a dilemma--the current stuff is starting to get a bit baggy, but I have not lost all the weight I want to. Should I get one set to carry me through or wait a bit until I get to my fighting weight??? Anyone need some used XL and XXL shorts and jerseys??

In a related thread that was on here just a few weeks ago, a couple of people posted summaries of data gathered from scientific tests which showed that clip & clipless pedals improved performance by at most something less than 0.5%. And I think it might have been closer to 0.2%. These improvements are vs using a platform pedal.
This was based upon the amount of force that one applied in the upstroke vs the downstroke. That the force of the downstroke overwhelms the marginal force actually generated on the upstroke side. I believe there was some data suggesting that for most riders, the difference is very close to 0, that you would have to really work at it to get it up to 0.5%.
I've since seen many bicycle shops advertising clipless as being 20% more efficient, and a couple claiming 30%. If one thinks about how much force they generate on the downstroke vs what they achieve on the upstroke, it is readily obvious that it is no where near 20%. You would have to be pulling up very hard - and it would feel like you lifting weights as you did.
I haven't reviewed the actual study or numbers, so I have no comment on their validity, although it seemed to be from a credible source.
I don't know if this holds true for all riders under all conditions. But I would think it would be very difficult to get anywhere near 5%, much less the claimed 20%. And if someone isn't working hard at developing and maintaining a very active upstroke, and is rather just pedaling along clipped in, I wouldn't be surprised at all if the difference was less than 1%.
If anyone has references to a legitimate study, I'd like to see them.

George needs to make the BIG commitment and go to a new Madone or Specialized S-Works road bike! Or maybe a custom-fitted bike.
No small steps this time George!

I don't really care if they improve my performance. They are just one of the things that indicate I'm a "serious" cyclist, and, by God, I'm gonna use 'em.

Riding clipless means: you're confident, you gots mad bike skilz, it's cool, its rad, you transfer 100% of your animal power to forward propulsion, you climb like a scalded monkey and float like a butterfly.
Riding without clipless (go for it, you grammarians) means: kids laugh at you behind your back, motorists despise you, women loath you (if you're a guy), you got lots of cellulite, you were lycra bike shorts on your head in the evening while you're at home, and you mow your lawn wearing bib shorts.

Yeah, but he was riding against other guys without clipless pedals. I hate to say it, and there is not way to really prove it, but I suspect that even in his prime he would have had a hard time with some of today's riders if they were using modern equipment and he was using the stuff of his time. I really believe that even riders of his era used the best equipment they could get their hands on.

The comfort factor of clipless alone makes a huge difference. Toe clips aren't comfortable for long rides. But they do have some strengths. For example, track racers still prefer toe clips over clipless pedals because of the added security of not coming unclipped. But once you get past track distances, give me some comfortable Sidi's with clipless pedals any day.
