The 2r is a great helmet. I used it on the first proper ride at Cymcarn last Monday (hottest day of the year so far). Took the chin guard off for initial climb but kept chin guard on for all the rest of it and it was great. Not too hot at all, comfortable and gave some peice of mind descending. After a low speed crash onto my face previously, I’ll be using it from rolling singletrack to descending to uplift days at bike park Wales.
Only snag is sizing. I have a 61cm head and the large only just fits ok. I need the dial tightened all the way, or it’s simply too loose. But medium is too small, tight on temples and a gentle of chinguard makes it contact with my chin. So definitely try before you buy.
