I bought these for a new pair of road shoes, but I've been using them since 2017. They provide good traction, clip in well and last a long time. I still haven't worn out my first pair. I even use these with Favero Assioma power meter pedals with no problems. I use the black cleats with zero float.
Since I started cycling "seriously" I have been a look fan. I don't pretend to know what degree of "float" will be best for you be be aware that Look cleats vary. I am 69 years old and routinely ride 30-60 miles at a time. I have replaced my cleats many times but so far (thank you God) never my knees. These also seem very durable as I get at least a full 5000 mile "season" out of them. Now the only issue is that when new they can become a bit difficult to engage and disengage. I use Finish Line Cleat and Pedal spray to help especially for the first dozen rides when I replace a set. I have found that to be a great product and believe you might no matter what your pedal system.
I've been looking for a saddle with a large relief channel for one of my bikes that has a low rail stack height to replace a Selle Italia Super Flow which is not comfortable for longer rides (longer than 3 hours). The low stack height is is needed for me on this bike to accommodate my fit because of the seat post height limit on the low side. After testing a few and reading multiple reviews and asking questions on forums I decided to try this out and it's exactly what I was looking for. I normally do a dozen more more 100 mile + rides a year, and this saddle has what I need to be comfortable on these. There's just enough padding and flex to be comfortable on long rides, not so much that it increases the weight. There's also plenty of room to move forward and back on the saddle for climbing, comfort etc. The nose is not so wide that it causes my thighs to rub it like many TT/short nose saddles but it has enough padding at the nose you can sit on it comfortably for a long time. The relief channel goes all the way to the tip of the nose too unlike some other options. Measurements that were important to me - rail stack height 44mm (in the center, top of saddle to bottom of rails). Nose of saddle 50mm wide measured at 40mm back from the front tip.
This seat post is expensive but what an upgrade, it adds a level of comfort I did not expect. I�m a heavy rider so this might not be noticeable to some but I can feel the seat post flex slightly on larger bumps and potholes, combined with the Cambium C13 saddle I might have the most comfortable bike on the planet. I have done plenty of long rides including a 105 mile mission and have not had to worry about saddle discomfort at all. The clamp is a bit tricky to set up especially if your used to the traditional clamps but nothing you can�t handle, an added benefit is the effective setback is definitely greater than 25mm if needed since the clamping area is so small. ENVE also supplies clamps for both round and oval rails, most companies would rather sell you the oval setup separately. I really can�t recommend this seat post enough, if you want to drastically improve your ride don�t hesitate to buy it.
