I'm 6'1" 215 pounds. I have always ridden bikes. As a child I rode and freestyled a bmx. Even now at 38 y.o. I have a freestyle bmx. Yes, the tricks have all but diminished but hey a 21" top tube on my Standard let's me pedal along with my children. I just started riding a road bike, originally as a way to increase my cardio and lose weight for dirtbike (KTM 525)riding. I think I'm hooked. In the past few rides I have had more pleasure with wildlife and smells and observing surroundings than I would ever have expected. My last ride was a little over 30 miles and my favorite thusfar. That being said, I know absolutely nothing about roadbikes and I feel like my lbs is either too busy or too impersonal to field a bunch of dopey questions. So here are some dopey ?s: Why are bike shorts so tall waisted...do they serve as a kidney support? I need to upgrade my pedals...since they will transfer to my next bike is it worth spending Dura Ace type prices..I have the ones(bearings are almost shot) that came stock on my Felt and I'm not sure if I dislike them or if the issue is my bike shoes are a little large. Why do people cut the steering tubes? If you buy a used frame fork with the tube cut what do you do? My bike is a 58 cm, I have heard a hardcore rider advise to go smaller when possible. I am considering going larger because one of the two ten speeds I had access to growing up was an XL and I thought it rode great. Maybe too much info but anyway my inseam is only 32" but my torso is long. In time I hope to buy a Specialized Roubaix or something comparable do I stick with 58 or consider a larger frame. My last question I haven't read the same thing twice whether I should concern myself with higher rpms or higher gears. I have a cateye velo 5. The only info i know is I average 18mph or a little better(it's very flat here). I don't want to replace the cateye but is there a watch or anything else good for keeping cadence. I know it's a lot of questions but I appreciate any help or advice.
