Member  62  Raleigh |  Subject: Time Difference b/w Tri-Bike and Road BikeSo how much faster are you on a tri-bike? I've been racing the last 5 years on just my old road bike because I swore when I got into this I was not going to spend a ton of money. I don't have aero bars or fancy wheels or anything. Since I don't mind coming in middle to back of the pack I'm OK with this. I'm just curious how much faster I could potentially be if I had a tricked out tri bike. |

Master 3888    Overland Park, KS | Subject: RE: Time Difference b/w Tri-Bike and Road Bike Not sure about tricked out tri bike but I have been professionally fitted to my road bike with clip on aerobars and use an aero helmet (Gyro Adv II) and I am 1-2 mph faster over 20-30 miles than the road bike w/o the aero setup. But it's not just as simple as installing aerobars on the roadie. I have a FF seatpost and a different steam than my road bike setup. But the cost of all that was in the hundreds of dollars, not thousands. |

Pro 6582 Melbourne FL Gold member | Subject: RE: Time Difference b/w Tri-Bike and Road Bike Likely 1-2.5 mph depending how fast you ride at with the RB. Here's a good read about a track testing vs wind tunnel testing for Road bike vs tri-bike setups. At 40 km/h (24.8mph) they measured about 60-70watts saved, if you ride the RB at 40 km/h then on a TB you should be over 44 km/h (+2.5 mph). |

| NH | Subject: RE: Time Difference b/w Tri-Bike and Road Bike Very unscientific n=1 result, but here's my experience: I have a ~15 mile loop I ride relatively regularly as a time trial. Road bike, completely setup for training only, vs. TT bike, fully kitted up with aero helmet and wheels, etc, it's a 3.5 mph difference. |

Champion 7136 Knoxville area | Subject: RE: Time Difference b/w Tri-Bike and Road Bike Many years ago i wanted to test it out http://www.beginnertriathlete.com/discussion/forums/thread-view.asp... tldr; ~2 minutes, and I wouldn't consider a Planet X Stealth a tricked out tri/tt bike even then. (Note... just n=1, YMMV a LOT.) |

Champion 9407 Montague Gold Mines, Nova Scotia | Subject: RE: Time Difference b/w Tri-Bike and Road Bike For me, from a typical road position, on the hoods, road helmet, training wheels, jersey and bibs, I was saving about 8s/km. That was pretty good aero position, aero front plus disc cover, skinsuit and aero helmet. Plus I tried to take care of little things (horizontal bottle between bars), clean cable routing, avoiding cylinders exposed to air flow, etc. This would be at oly effort so a difference of about 3km/h (and that's definitely not with a high end bike - Leader 730TT - basic alu tri bike).
