The Race elbow/forearm carries on the traditions of the knee/shin, in an elbow pad that does what it needs to do. It stays in place with its X-fit design, and stays cool with perforated EVA protection.
The fox Titan has a better fit than these although the 661 may provide better protection. Had no issue with the Fox pads, however, the 661 pads I had have a noticeable lack of mobility.
Nothing like adding confidence for bombing it downhill. These are light enough and flexible but offer a lot protection. 6 months in they are holding up well. I wouldn't wear these on flat XC ride but if you are going up then down put them in your backpack and put them on before you rip downhill. Easy to put on, stay in place, adds that extra peace of mind so you can charge it a little harder knowing that if you bite it you won't shred your skin. 4 stars because things can always be improved
