I had the original Blades, and have always loved the look and feel of these pedals. The lack of conventional metal springs is naturally appealing, and the innovation of taking advantage of the tensile strength of carbon is really cool. Anyway, I bought the new Blade 2 and I have to say that the innovation imagined in the original Blade is realized in the newer model. One weakness had been that the asymmetric design puts ever so much torsional stress on the pedal body, which over time leads to less pressure in the system. In other words, it was noticeably less grippy over time! These new pedals have a wonderfully audible click into place, and the feel is secure. No likelihood of popping out in the sprint in these bad boys.
This new design makes this pedal better than ever. It always seems to be in the right position whenever I need to start again while riding in traffic. Great looks and lightweight too!
I've had these mounted on my CAAD10 for about 5k miles. These are the lightest Look pedals I've since I started using Look in 1992. They have a decent platform, click in securely, and spin nicely.
I'm not a fan of two attributes the unweighted balance (these pedals will not rotate to a consistent location since there is not enough weight) and the sharp outside edge.
Unlike previous Look models, there is no consistent way the pedals rotate so you will be learning foot dexterity to position these correctly to clip in. These pedals would not be suitable for a crit racer unless you consistently pre-position each pedal prior to the start (not terribly difficult, but who remembers to do that before every race?).
The sharp outside edge caught me by surprise one day when I clipped out to stop suddenly at a light. When I finished the ride I felt blood running down my leg from a long scrape from low on my calf. When this happened again I checked the pedal and found a very sharp edge on the outside edge closest to my calf when standing astride the bicycle. I filed it down a bit to dull it some but it is still can bite.
See my previous review. After riding these for several thousand miles I finally reached the point where constantly looking down when leaving a stop to see the pedal orientation, flip it if needed, then align the cleat to the required angle to clip in...I finally listened to my riding buds who've been on SpeedPlay for years and switched. I should have done this years ago...there is no 'right side' to the pedal...I don't need to look down for any distracting orientation and snapping in is a breeze. I got SpeedPlay specific shoes and enjoy lower 'stack height' and increased cornering as well as larger cleatshoe interface area. There's no going back to single sided pedals for me.
PS Doing 200miwk avg...flipping pedals IS...was...a bid deal.
I have ridden KEO pedals since they came out and one thing I have noticed is the grip cleat is more difficult to clip in at stop lights, etc. The grip material will sometimes catch on the pedal as you are engaging it and you have to try several times to get clipped in. I switched back to the regular KEO red cleat without the extra grip material and it is much easier. You just have to be more careful walking around at the coffee shop.
Finally made the conversion to some modern pedals after many years on Crank Bros Quattros. Decided to try these Keo Blade 2 because of wide pedal platform and light weight - and a good sale price. Read about the problem with spinning resistance and difficulty orienting for cleat entrance. After about six rides, I like the wide platforms - good pedaling stability, no hot spots. I do have the problem of a lack of spin resulting in tricky pedal orientation before clipping - takes a few extra seconds of concentration to get the pedal around in the right orientation. Hopefully, pedal will spin to good position as the bearing seals wear a bit. Will also try some lubrication, perhaps.
I had the previous version (2013) of these but went down hard and broke one. The changes to this pedal mentioned in the description are good but the smaller stack height has made it significantly more difficult to get clipped in with my Look Keo Grip cleats. Once clipped in the benefits of upgrades mentioned above are welcome. I would trade off the improvements of this current version to get back the 'relative' ease of getting clipped into the previous. But, since those are no longer available I think these are the best pedals on the market now.
