Anyone have any experience with these?
Seems the pedals themselves are more or less problem free(for lighter riders) if you don't mess around with the tension adjustment.
The cleats are the problem. I have a pair of original Time xpresso 12 pedals on a second bike to compare with but I've never tried the original cleats.
One problem is with two of the cleat bolts. They are way too easy to pull through the cleat under pull situations. These need to have a larger diameter head. Original is 9mm but space allows for 12mm so the titanium ones I ordered with 11mm have worked fine even to the point where the cleat is so old and raggedy it's falling apart. Its passed the test sort of speak.
Warning: If the bolt heads aren't low enough the cleats won't engage well into the pedal and you will get dangerous accidental unlocks. I noticed that when clipping in I can feel by twisting my foot a bit if my cleat is fully engaged or not. If it's wobbly it hasn't fully engaged. Simple twist and push fixes that right away.
The cleat quality is very poor and part of it is because of design. Two big problems:
1. The cleat is very big and so big in fact that the shoe won't be able to support the cleat. Part of it is just sticking out to the sides. (I suspect shimano spd-sl are similar). The unsupported parts are then walked upon and start to break.
2. The total walking surface is very small so the cleat will be ground down quite fast.
I found the seller of costelo pedals here in China also sells dirt cheap cleats for 6-7usd a pair. I bought myself a few spares and thats that. If I had to pay time retail I'd definitely go back to Look pedals and cleats.
Can't comment on axle strength, I'm a small light guy.
The tension adjustment on these is a plastic slotted screw-I've managed to have one strip, poorly molded. But the tension adjust can be ignored.
Decided to try them out. As others have noted one of the pedals did not spin freely. Seems like the nut that tightens the pedal onto the spindle was over torque. I backed it off 1/2 turn and pedal was fine. Went out for a short 20mile ride to try them out. All good.did you have problem with poorly spinning bearings as had fake Xpresso 12 pedals?
The pedals I got were 81g each. Hope they last!
If you are not in a hurry, you can buy the originals for a reasonable price (it takes about two weeks for the shipment to arrive .)
Are Shimano DAs better? I think they feel more solid, and last very very long (even the cleats.) However, the float on xpressos have been good for my knees, and they are very light (154 gr, without the cleats.)
Is there any real gain with ceramic bearings except for 20g savings?
May there be any performance difference between DA and Xpresso or it is just about how long they last or how they survive in case of crash?
Performance gains from ceramic bearings in a pedal? Of course not. There may not be any in hubs or bbs either. Matter of debate.
DA pedals are considered to be the most durable raceworthy pedals out there. Like most DA stuff, the extreme functionality comes at a weight cost. Its up to you to decide. Of course there are tradeoffs, that's the way things are.
