IT does take time to get used to the descent. When Gina first wen up she was doing 10-15 on the dh riding the brakes. After doing the climb several times she now descents at 20-25 and maxes out at about 33 or so. I've seen some really good climbers that couldn't descend for beans. We did a forum ride once. One guy was probably 3 or 4th up the climb out of 30 riders. But heading down he couldn't do more than 10 mph. Seriously! I don't know how that happens but after he ad to wait for others at the top for 10-20 minutes, we had to wait for him at the bottom for about an hour.
We have a ski resort called Mt. Wintergreen. It is a fairly steep climb to the top, and they have a springtime hill climb race. I made the climb with a buddy of mine.He and I rode together, but he descended like a pro, hitting 55 on the way down. I hit 35, but wouldn't go any faster. I feathered the brakes, mindful of the rims heating up and rendering my brakes useless. He had to wait for me. I do remember descending into those mountain towns at the base of the mountain and realizing I was exceeding the speed limit of 25 mph in the town. I was expecting to see a blue light special but got through the town unscathed. Stopping would have been difficult, too without standing on the brakes. I might have been cited for felony eluding.
