Well we're back in the 100's so too blasted hot unless it's early. Started a ride yesterday at 8:00 and .5 mile into the ride snapped my 22 tooth gear in the cassette. (Don't ask me how, I was going downhill ). The guys teased me about my powerful legs. I was able to continue riding but after a few miles told my friends it was too hot and I was too distracted knowing that if I shifted up too much I was going to hit that hole. Ordered a new cassette and chain when I got home.
