The main selling point of new xtr pedals is the additional contact area which better supports your foot. On the xtr trail pedal i would easily agree but on the xtr race pedal? I don’t quite know. If i had to really really really assess what my foot feels like id be inclined to say it feels slightly itsy bitsy different but to be honest, i hardly felt much change at all. Especially after being spoilt with the platform monsters that is road pedals.
Some mods are worth more than others. If you have old xtr pedals, hold up on going for the new xtr race pedals. The trail pedals are 100% worth getting but the race pedals i am not so sure. On top of it all, apparently, the new xtr race pedals has issues clearing mud. Awesome.
