Dumb things that I learned this weekend about mountain biking & other mechanical things.
1. There's a rear and a front break that work separately?
2. Oh, mountain bikers wear gloves so they don't have to pick rocks out of their hands when they fall. I get it now.
3. The reason that people 'jump' things on their bikes is so that their tires don't get stuck in large dirt divots and stop abruptly as their bodies keep moving.
If your afraid to fall, then you shouldn't ride. If you never fall, then you may not be pushing yourself enough. You won't progress without testing your own limits.
I have played rugby for 7 years and believe me, I am not afraid of bruises, bumps, and contact. I recently injured myself pretty severely playing: torn ACL, medial & lateral meniscus. Yet still I would rather go through the pain and torture of surgery than live life afraid to try.
