The 77designz 1*11 chain guide is amazing; it´s super light, mounted in no time and mean while quite affordable. It´s designed in Germany and tested during many Enduro and Downhill races in all over Europe. And of course is the freesolo also fine with 1*10 drives as long as you use an tensioned rear derailleur and an narrow / wide chain ring.
