Review on SHIMANO SM CRM85 Direct Mount Chainring Black by Mark Vazquez

I had a 32 tooth chainring, as I do very steep and difficult climbs I decided to set it to 30, the results were amazing. Now I can climb much easier and have become more efficient in terms of climbing speed. I just have more cadence than before because I can shift gears or play with more sprockets and you either ride easier or faster uphill. My combo is 30 front and 51 rear (new Shimano XT 12 speed groupset). Cool group, it really breaks the competition!
