Good for you riding those ball bearings y'all call 'smooth'. I've done Baldy to Gashouse Gulch and it was nice but more technical than a beginner trail you'd find over here, because of those gravelly granite pellets. If you're riding those up or down you're doing a darned fine job, no matter how long it takes you. Keep up the good work, keep pedaling everywhere you can as much as you can and know you're doing well. The speed will follow the experience.
