For those interested in a light pedal, I have bought and tried the Look Keo Blade pedals.

They are smaller and lighter than the Delta pedals at 230 grams per pair. The spring isn't metal but a carbon fiber plate that seems to work quite well.

The one problem is that they are so light that they do not rotate into the proper position to easily click into them. The low friction of the bearings is almost to high to allow them to rotate reliably. Now perhaps the bearing seals will wear in and allow the pedals to be more reliably rotated so I'll see about that.

The cleats are smaller so if you intend to use pedals like this you should have solid carbon soles on your shoes to prevent getting a hot-foot on long rides.

These smaller cleats are a great deal more difficult to walk on polished surfaces on so be sure when you buy the pedals you also order the rubber walking cleat covers at the same time. My old Delta covers work half-assed but fall off easily so if the Keo covers don't arrive on time you CAN use the old Delta covers for a short while.

My overall perception of these is that I will change over all of my bikes to these pedals. They seem to hold the cleat in more reliably and they click out easier.

OK, I did a nonstop 50 miler today with nearly 5,000 feet of climbing. I was SLOWWWW with just under a 10 mph average. Part of this was because it was almost winter-like weather with wind blowing in your face no matter what direction you turned. And I had only a thin long sleeve jersey and shorts on.. The gloves cut off the circulation in my left hand and finally I couldn't shift. I removed the glove and only got partial use of the hand because it was so cold out.

In any case I gave the pedals a very good workout. My impression of them now is even better than it was Sunday.

Because of Jay's comments about the carbon clip spring getting flaccid I bought a rebuild kit to keep on the shelf. As is usual with this, Jay's experience was probably an outlier and I'll have this kit on the shelf forever.

But they are so much easier to clip into than the Delta pedals and they weight a little less @ $100 as the top of the line Delta Looks at twice the price it seems a good idea to replace all of those pedals. Or with my luck the price will double in a week.
