Expert  1375    McAllen |  Subject: RE: Best equipment to gain speed on bike?as a fellow engineer I understand exactly where lifejustice is coming from. However, he is also wrong. Faster can be defined as getting from point A to point B in the least amount of time. Lifejustice is saying that the forward force generated by rider A (lets say 500 watts) will be faster than the forward force generated by rider B (lets say 300 watts) even though rider A can encounter 400 watts worth of resistance and rider B would encounter only 50 watts worth of resistance: Meaning rider A would be pushing forward at 100 watts (assuming no resistance) and rider B would be pushing forward at 250 watts. Saying rider B slowed down less, but is still "slower" than rider A would be wrong. At least that's what I understood from Lifejustice's post, so please jump in on the semantics if I'm wrong. I love this thread!!! |

I love this thread!!! Force is not measured in watts. Power is. If the net effect of the power output of the rider and the resistance is not zero, the rider is accelerating or decelerating. |

Expert 1375 McAllen | Subject: RE: Best equipment to gain speed on bike? Ugh I should have re worded forward force with just "forward vector". I hate myself a little now. But power is related to force so I'm not totally wrong! P=F*d/t.... |

Veteran 287 | Subject: RE: Best equipment to gain speed on bike? If you don't already have one getting a good trainer and using it will make you faster than any aero bars, aero helmets, or aero wheels. It doesn't make your bike look cool when you're out riding, but an ever growing FTP is always cool. It means no more missed workouts due to weather and no off season for the bike. Pair it with trainerroad and a solid plan for killer improvements in a short time span. |

Force being measured in watts is an issue but beyond that, the idea of a force being "faster" doesn't really make an sense and it would appear that you are attempting to address the acceleration phase of riding as opposed to the steady state situation that is most applicable.

ShaneThat was just my interpretation of lifeforce's idea of the physics of a moving bicycle. I never really broke it down before myself, so as a defense to my own pride my only error was with the force/watts thing x) but I'll definitely read the article! Time to expand the mind. |

| Veteran 353 41° 4' 36" N 71° 56' 10" W | Subject: RE: Best equipment to gain speed on bike? I bet that most of these things will help with the speed. I didn't understand all of that early on, so I focused on the conditioning. To date, my fastest bike times were still wearing my running shoes while strapped into the pedals. I was 10 pounds lighter so I could climb better. I was in my running shoes so my T2 was like 30 seconds. I was doing a lot of interval work. Lots and lots of 60 seconds all out and then 60 seconds at 75%. then I'd do 120 second all out. Then push it a little longer with races coming up. Granted I was only doing sprints and Olys, not sure how that would have worked on the longer rides. My back used to hurt after 30 miles. maybe fit would have helped more back then. These days I dont have the ability to do that kind of speed or acceleration, but a 50 mile bike ride is no longer a problem. I did work on my fit and now I feel I can hold it together better on the longer rides. It was good for me to just spend time on the bike on the trainer. It was key to sense that something that felt a bit uncomfortable at 10 minutes might turn into agony after 60 minutes. I saw how I was holding back, not becuase I was tired, but because I ached. |
