"Well, Tom, you are a miracle worker! On the way to the mountain, I did a 20 minute "tempo" ride at 130 Heart Rate; then 2 intervals of 8 minutes at lactate threshold 139-145 HR with a two minute rest in between, then two more 8 minute intervals up the mountain. I was able to either use the granny gear and spin faster to get my heart rate up to LT, or drop down a gear or even two and stand up to get my HR up. Then when it was time for a rest interval, I could just sit back with my granny gear and my HR went down to 127 while still climbing. But the miracle is , this hill is where I would always get back pain shortly after I started up it. By the time I would get to the top to the Ski lodge, I would have to get off and lay down on the ground for about 10 minutes to alleviate the pain.
But today, I rode right up to the top with NO BACK PAIN whatsoever. When I got to the top, instead of stopping, I just kept going. I reached back to my new pack and got out a flax bar, ate it while I was riding back around the lodge before I started back down the mountain. I rode all the way home, a total of 25 miles with NO BACK PAIN."
A couple months later, Rick writes...
"I absolutely love my Titanflex. I am riding 100 + miles a week now. Unless I tackle a lot of big hills, I am able to average 17 miles an hour, which I could never do before. I also have no more problem with back pain, which is almost unbelievable. I set a goal 1 1/2 years ago on my 55th birthday "To be as fit at 58 as I was at 28, weighing 168" I weighed 233 lbs at that time, Sept.28, 2007. Yesterday I weighed myself for the first time in a month, and I weighed 165.5 lbs. And I have another year and 4 months until my 58th birthday. I had plateaued in my fitness and weight at 175 until I got the Titanflex. Then, reading a couple of books about cycling, I was able to begin bike training with new understanding of heart rates, etc., and am now possibly the fittest I have been since high school. My brother, who is 61, is a huge inspiration to me. We are planning on riding across the US next summer."
