Joining the pre-Tour de France new bike launch frenzy, Cervelo has just released their new S5 aero road bike. Alas, without seeing data, it’s impossible to say whether form followed function or not. I ‘ ve seen Cervelo 2012, S5 the white one, I can say, the white color one S5 looks better than 2008 Beijing Olympic one, very shine, one of best, It will beating any bike on the market from mane different ways, I hope that I can gat a white one, no black one !!! Rode this bike the other weekend, dream machine, climbs hills like floating on a cloud, unbeleivable ride! Want to Contribute?We’re always looking for enthusiastic, positive and talented writers that know their way around both a bicycle and sentence structure. This puts them in the growing category of fast, comfortable bikes, but introduces some interesting technology. Elastomer inserts on the lower rear fork legs sit just above small fender bolt holes, which are also on the rear dropouts. Considering this is the manufacture partner of Specialized its no wonder it has aspects that resemble a Roubaix. Provided there’s actually come clearance at the brakes (unlike a big American brand) then having the ability to put mudguards on a bike is hugely convenient. On the Gary Fisher Cronus (the proper road bike, not the CX bike) the fixing bolts for the brake calipers had a thread inside them for the top of the mudguard to fix into so you could take them off without having to remove the brakes.
TPE16: Praxis goes carbon, shows gravel ready micro-compact rings, chainguide and MUCH more! Unless they pulled some photoshop magic, the frame barely registers beyond the tire’s frontal profile.
Up front, which is better seen from the side profile pic at the top of the post, the downtube starts really low, which lessens the gap between the fork and front wheel, which Cervelo says keeps air running smoothly from one surface to the next.
It’s just to bad that the bikes built for average Joe cyclist are held back by these UCI rules. Triathlon Bikes I am constantly asked what the big differences are between road bikes and triathlon bikes. From there, the downtube was shaped to maximize aerodynamics even with a standard water bottle and cage attached…particularly when mounted to the lower of the two available positions.


The stainless Firefly road frame is setup with a Campagnolo 11 speed drive train featuring Super Record shifters, polished Athena derailleurs and Cannondale Hollowgram Si SL Cranks. The obvious difference is the fact that one races a triathlon in an aero position, but sometimes we see aerobars on road bikes so what is the real difference? The flattened chainstays and thin seatstays should provide a bit of compliance in the rear. While I ride my cross bike most of the winter it would be nice if I could throw fenders on my road bike in the early spring when weather and road conditions can be sloppy but I still want to get miles on my race bike before the first race of the season. You might think it’s an eyesore but that won’t matter to the guy who’s riding one as he passes you and won’t be concerned enough to look back. There is a smaller difference between UCI legal time trial bikes and triathlon bikes, though they look very similar. The short answer is, road bikes are designed to have three hand positions, triathlon bikes are designed to have one. The Enve rims and C-4 hubs are a recipe for speed and those EE Cycle Works brakes will help bring you back down to earth. They are designed to be able to do all that a road racing bike does and in fact, bicycle racers use the aero position of a draft legal triathletes all the time.Time trial bikes that are UCI legal have saddles that are set back further than triathlon bikes.
The bike is setup so the rider has to actually ride on the nose of the saddle (on the rivet, as they say) to get the proper balance point for the effort being produced. Since a time trialist is racing at max effort, the most efficient position is in front of the comfortable point on the saddle, so riders just tough it out. They don't have to be comfortable and their events are rarely longer than about an hour so who cares?Triathlon Bikes: Position is keyTriathlon bikes are designed to be ridden for longer distances and at a submaximal pace. This means that the rider will be putting more weight on the saddle and aerobars because they are not pounding the pedals hard enough to support themselves. As such, the saddle and aerobars are located in the place the rider is the most efficient or most aerodynamic.
The reason I distinguish between the two is traditional triathlon positions are very far forward to accommodate a triathlete's greater hip angle needs and to allow a super aero position. First, the position is not powerful and many triathletes give up more power than is gained by pure aerodynamics.


Second, the further forward one is positioned relative to their balance point, the more front loading occurs on the knees and overcompensation by quadriceps occurs. This muscle imbalance is paid for in the transition and the start of the run.The perfect triathlon position is the one where the rider is as strong and aero as possible, with enough comfort to be able to stay in the aerobars the entire event. If you have to sit up during a race to rest because the aero position is not sustainable, you have a problem.
Remember, though, power trumps aerodynamics to a point, so your best position may not be where you think it is!Can a triathlon bike be as aerodynamic as a road bike? Since the position on the bike and the setup of the bike to support that position are the two defining differences between a road bike and a triathlon bike, what about all the aero tubing on some frames and the round tubes on others? Some frame manufacturers advertise how fast their frames are based on wind tunnel testing, but I think that is a lot of marketing hype for the most part. Here is a critical fact: The part of the time trial or triathlon bike that creates the most drag is the rider!
The frame is inside the boundary layer and as such doesn't make as big a contribution to aerodynamics as one might think.The concept of a boundary layer is a tough one so imagine the air right next to you going the speed you are, and at a certain point away from your body (and the bike) the air is undisturbed.
This means that the 2" part that was sticking out of the fuselage had virtually no real aerodynamic detriment!What all this means is, a road bike with aero tubing still won't be as fast as a triathlon bike with round tubing, assuming the rider has a good position! What this also means is, the aerobars, fork and front wheel have a huge impact on aerodynamics as they are outside the boundary layer. Third, having a good set of integrated aerobars that have the shifters at the ends of the aerobars is important.
You have to move around to reach back and get those saddle mounted bottles, so that is an area that could yield good results.Triathletes are in charge of all of the aspects for all three disciplines in the sport.
The bike is so critical and yet so overlooked it is not surprising that much bad information travels around the transition area.
