it was a joke kid... and my argument... for the 1000th time... wasn't saying Icon was crap... it was that they don't have the rep that Teknic and A*'s has... and that they're products as a whole are flashier than most others.
and yeah FTW is for the win. FTL is For the loss.... I used to think it was FUCK THE WORLD! and couldn't figure out FTL was either |

2. Well,if you read my post,I was talking about ALUMINUM sprockets making a $159 Ti sprocket economically feasable and specifically said that it doesn't make sense to a steel sprocket user. Guys that purchase Alum sprockets care about weight savings. BTW most people only change gear ratio once. 3. I mentioned front sprockets to agree that $89 was way too much since fronts don't "seem" to wear out. 4. then why fuck with it? I was merely illustrating that running your bike at higher rpm can have adverse effects which include; lower gas mileage, increased engine wear,increased vibration,inacurate speedometer,confused engine/fuel mapping,etc. Like I said,I ride my bike all the time in various capacities and don't want to narrow it's focus further by modifying the gear ratios. The engineers spend hours,days,weeks developing the trans,engine control computer and gearing to find an all around good working compromise. For example,an engine might have a definitive rise in vibration at 7000 pm. So the designers set the trans and gearing so that at 70 mph the engine spins at let's say 6500 rpm in 6th gear thus avoiding dead hands and feet after a freeway jaunt. After you installed sprockets with two more teeth in the rear and one less in the front. It spins at 8500 70mph in 6th gear. Now you have sleeping hands and you've lost 5mpg in fuel economy. Yea it's real smart to set your bike up for that one in a hundred rides "Veyron" race and sacrifice your day to day comfort and over all capabilities. Sure. |

Here's a thought. Lets say two guys have identical bikes. One guy commutes on the interstate back and forth 20 miles and averages about 80 mph on the trip. We'll call this guy Tigger. Another guy, rides 20 miles to work, but cuts across a mountain, and averages 60 mph on his commute. We'll call this guy Warputer. Now, Tigger, since he rides on the interstate, likes his gearing. If you don't believe me, ask him. Warputer, on the other hand, wants a little more torque since he avoids the highway, and stays lower in the rpm range during his commute. Warputer makes a change, which results in 20% change in the gearing towards the lower side. Now, even though the two bikes have significantly different gearing, they are running at the same rpm range through the commute.
The point being, if someone lowered their gearing, they are probably riding at lower speeds, and any additional wear and tear from increased engine speeds will most likely be negligible. In the end, gearing is just like jacket designs, oil, bike brands, and women. It is personal preference. No one is right, and no one is wrong.
