comment Does a 700c wheel help you go faster?
I did look at your thread posting, did you?! If wheel diameter[radius] cancels out like you say, it wouldn't be IN that final equation: a = (2t)/(R(4m+M)) a=acceleration/t=toque/R=RADIUS of wheel/m=mass of single wheel/M=mass of rider&frame. The fact it IS there proves that it is relevant. It's become plainly obvious you didn't understand any of the math that was presented nor the concepts. I too am weary of this though I am sure you will probably make one more post just so you can have the last word.

comment How fast do you need to be going to get an effective slipstream on a bike?
It's my understanding that the pocket behind the lead rider gets elongated the faster they go. The extact size of the pocket could be calculated using math but suffice it to say that the closer you are the better for both riders it is. exploratorium.edu/cycling/aerodynamics1.html

So you're saying the length of the lever has no effect on the force needed to move the mass? Archimedes would probably take issue with that statement. However, the MoI of a thin hoop is defined by I=MR^2, as per Newton. You change the [M]ass or you change the [R]adius and you change the MoI. Your linked thread even proves this(acceleration is inversely proportional to the Radius of the wheel times the mass) but I guess you have the right to believe what you like.

Agreed, it is physics, Newtonian physics actually. I've been talking about the difference in acceleration between a small wheel and a large wheel of equal mass. You seem to be hung up on rider mass vs wheel mass distribution which I haven't really talked about. Original post asked if a 700C wheel would make you go faster than a smaller wheel. I formed an answer for the question and your link helped prove my point. Thanks.

comment Does a 700c wheel help you go faster?
I agree that a pound of mass on the frame is the same as a pound on the wheel if we were simply dragging the bike down the road on its side. However I'm talking about MoI of a rotating hoop and the numbers don't lie. If you shorten the radius the force needed to rotate that hoop decreases. Do the math yourself. Anyway,700c wheels were tradtionally sew-ups, which meant you could run at 130psi+ compared to a clincher at 90psi. That's probably where the whole debate started. 26in/27in/29in -all will go as fast as the rider can make them go just make sure they have race slicks at rockhard psi.

comment Why Do I Need a Better/Lighter Road Bicycle to Train For 'Fitness'?
I would guess the mind set of the sales people is if you are going to do fitness then you are going to be more serious about riding and in turn want/need a better bike than what they are trying to sell you. Experience has shown me that people that say they 'want to commute' to work want to pay about $100 and try it. People that want a bike for fitness&commute ride because they have fun on the bikes. Reality is that a low end bike rides like a low end bike and you'll be less likly to just go for a 'fun' ride. You don't take a panel van out for a sunday drive, you take the convertible.

comment Tube constantly getting punctured near the valve
Your tire is slipping and pulling the tube along for the ride? Put talc inside the tire so the tube and tire slip and DON'T stick and cause pinches and stem rips. Also could make yourself a gasket ring for additional stem protection as well as taking a file to the rim and smoothing out the edge. Yeah, clean your tire too so the rim grips it better but you'll always get some slippage when riding under inflated so what you're looking for is a frictionless interior.

comment Front derailleur is hard to shift into the big ring. Where to start?
If cables are good and limit screws are set then an old school tweak is to take a set of needle nose and slightly bend the front of the chain guides of the derailleur inward. This will narrow the guide just enough up front that the chain will respond better to shifts, but because the back is left alone you shouldn't have chain rub issues.

comment Problems with a slipping seatpost
Quick release seat clamps never work for me as I'm a big guy and unless I use a allen bolt type I can never get them tight enough. As it's integrated into the bike you might have problems fixing it. Go back to the shop and have them check things out for you.

comment Straight-pull spokes - worth it?
I ride both mtb and road. Spokes have always broken at either the elbow (90%) or the nipple (10%). Yeah, I know it sounds weird but the nipple as snapped on me twice in my 35 years of riding. I use regular spokes on the mtb and butted on the road. I also stay away from the top end parts because they are made for racing and have the lifespan of a fruit fly. I've always gone 1-2 steps down from the top and get far longer use than my buddies with a weight cost of a latte. Just something to think about.
