"I tested the new ONASPORT CLM from Tri-excellence. I needed some care to wear it correctly the first 2 times when I was wearing the sensor, but after that I had no problems. When you use the sensor, you can forget it, it's exactly like a heart rate band. It's amazing to have the possibility to check the real-time lactate, as well as the sodium-loss and the sweat-loss.

In my experience all parameters are quite reliable, especially lactate (which is the one that is most important to me) is very much in line with measurements made with the standard method.

I really appreciate the sweat loss and sodium loss measurements. It helps a lot to integrate the right amount of water and sodium in my training. You can really know how much is your sweat-rate. For me it is crucial to know how much sweat I have lost during training. Also in hot seasons I now know how much I need to drink. I can now also make a good sodium-intake-strategy for the race.

The lactate measurements of the sensor for me are coherent to my heart-rate and used power on the bike. It is important to keep my race-pace constant and to understand well what will be the right power to maintain for the race. The lactate sensor measurements help with that. This is very important and I love that.

I think the sensor could become the new 'must have' for every athlete"
