In becoming accustomed to the mental strain of riding this close to your FTP, both physical and mental adaptations will occur, and your confidence in performing future workouts and events will increase. A pacing strategy is an essential piece of the puzzle for a rider seeking their fastest time trial. Nearly all time trials reward a negative split pacing strategy, which centers on going faster the second half of the race. That means starting out easier than you can sustain, then building towards the top end of your sustainable power by the end.
This is one of the most challenging aspects of time trialing but one that reaps massive rewards. This is a sweet spot where your body experiences the least amount of fatigue but carries the highest overall speed. Having a power target for race day is an integral part of the planning process. Your time trial training gives you plenty of opportunities to practice your target power.
This is the reason for event-practice workouts starting in the Speciality Phase. If you have been riding your practice time trials, you will be familiar with your power and previous performances.
Practice time trials will familiarize you with the demands of your goal event. It also means finding the balance between aero, comfort, and power production with your bike fit. Being familiar with your position and your equipment is essential to feeling confident going into your event.

UCI rules currently prohibit the use of such deep tubes or fairings, but cyclists taking part in time trials governed by the CTT Cycling Time Trials — a UK-based governing body for time trials not regulated by the UCI can take advantage because its rules are much less prescriptive.
The extensions protrude forward, and, combined with the armrests, allow the rider to adopt and maintain a more aerodynamic body position than would otherwise be possible. The armrests and extensions should be adjustable for both width and reach, to allow you to fine-tune your position. There are many pages of rules dedicated to restricting the range within which the extensions and armrests can be positioned in UCI sanctioned events, though.
Outside of UCI governed events, this is unlikely to be a concern. For this reason, time trial and triathlon bikes are generally not deemed suitable for bunch riding outside of the team time trial , of course. Aero is practically everything when it comes to time trial bikes, with weight being of only minor importance. Because of this, tube shapes are optimised to be as slippery as possible, within the UCI rules.
While older time trial bikes used narrow aerofoil shapes , modern machines have gravitated towards wider, kammtail shapes. These larger shapes are intended to trick the air into behaving like a much longer and therefore more aerodynamic aerofoil shape is present, and also provide benefits in terms of stiffness, weight and shielding water bottles from the airflow.
The geometry of time trial bikes also differs from that of road bikes. The most notable difference is that time trial bikes typically have steeper effective seat tube angles around 75 to 78 degrees compared to road bikes. This can negatively affect handling, particularly on descents. The use of solid rear disc wheels and front wheels with ultra-deep rims or low spoke counts such as tri-spoke wheels are typical in time trials front disc wheels are generally only permitted for use on the track.
Until recently, bike manufacturers put a lot of effort into dreaming up aerodynamic solutions to hiding rim brakes within the fork or under the bottom bracket. This usually meant compromised braking performance or complicated servicing or both , but was considered to be acceptable in the pursuit of aero gains.
Many have argued this is a step backwards in terms of aerodynamics, but removing the requirement for the rim to act as a braking surface, and for the frame to integrate two relatively large sets of rim brakes, opens up new design possibilities for wheel and frame manufacturers. This is because it enables you to brake later and with increased confidence, which — all else being equal — helps improve your average speed. Time trials often take place on flat or rolling courses, so riders chasing every advantage can optimise their gearing to suit.
This typically means large chainrings tooth or larger and closely spaced cassettes. The former is useful for optimising chainline, and the latter helps riders modulate cadence more precisely, which can be important when riding close to your physical limits. Given power is lost to friction within the drivetrain, dedicated racers will also look to optimise their drivetrain efficiency as well. This means larger chainrings, cassette cogs, jockey wheels , as well as fast chain lube , high-quality steel or ceramic bearings and even 1x drivetrains or short cranks.
Think of taking five pounds of theoritical weight. First, add it to the saddle. Try to imagine what it feels like. Now, remove it from the saddle and put it in the bottom five inches of the down tube. Now try to imagine what THAT feels like.
Now imagine each situation over a ten mile sprint. If you just don't give a damn about this or believe it makes no difference, then please don't hesitate for a minute to go to another thread and leave this one alone. I want to hear from those who truly are interested in this theoretical question. If it were only that simple! The site has to do with sales, not tech weenie stuff.
But thanks for the effort! Okay I just came back home from a Two hour ride, went to town and put at least 4 pounds of groceries in my milk crate. I definitely notices a difference out the saddle sprinting on the flat roads.
All the wieght up high just makes the bike feel more flexy but I still accelerate about the same. That same wieght feels easier to ride with when in the saddle and not straddling the bike side to side so much.

Shifting comes courtesy of Shimano's Ultegra mechanical groupset, while braking is taken care of by Bontrager XXX levers paired with proprietary integrated Bontrager calipers. All of this is built onto a series OCLV carbon fibre frameset, which helps keep the weight down to a respectable circa 9kg 20lb level.
The seat tube is a pretty aggressive degrees, which is matched by an equally-steep With a close connection with the forward-thinking HUUB-Wattbike team and their aerodynamics expert Dan Bigham, the Ribble brand is quickly growing prominence in the time trial sphere. With Ribble's online BikeBuilder tool, you are able to choose your own spec and adjust the bike's colour at the point of purchase.
In a size medium, the stack sits at This is paired with a head angle ranging from Scott's Plasma 10 is the direct benefit of trickle-down tech, as this frame design sat at the top of the range with a massive price tag only a few years ago.
Now, at a much more budget-friendly price point, the Plasma 10 is still one of the fastest bikes on the road. With the seat post in the steeper option, to cover the extra hole in the frame, there is a removable storage box for tools and spares which complements a top tube bento box and dual-standard bottle cages.
Bianchi has incorporated its Countervail technology into the layup, which integrates a viscoelastic resin used by the likes of NASA into its carbon fibre and is claimed to absorb 80 per cent of the vibrations coming through the frame.
The Italian outfit also says it not only helps the rider stave off fatigue but also increases the stiffness of the frame. On the outside, every detail of the Aquila TT is sculpted to cheat the wind. The front brake sits inside the carbon fork, the rear brake is found beneath the BB, and the frame has an adjustable rear dropout which allows you to snug the rear wheel up against the seat tube to maximize aero gains. At the front, the Aquila features a proprietary integrated bar and stem system, which does limit adjustability to a certain degree.
Cube's Aerium has a funky silhouette, with sharp angles that make it look more like something that should be lining up for a light cycle match in the movie Tron rather than at your local TT.
Made using the brand's Advance Twin Mould system, the bike features rear-facing horizontal dropouts that allow you to snug the rear tyre right up against the seat post for the best possible aero benefit. All of the cables are hidden inside the frame except for the front brake, which utilizes the brand's Aero TTVO1 caliper.
For the money, the bike comes with a full Shimano Ultegra drivetrain R and roll on a set of Mavic Cosmic elite wheels, ideal for training. You sure can, and with a set of clip-on aero extensions, you can get a feel for the TT position and some aero advantage. That said, not only will the time trial bike itself be more aerodynamic, the geometry also differs quite a bit to help you minimize your body's front-on profile — which is what creates the majority of the drag.
To start, the seat tube will be extremely steep usually around degrees , placing your derriere directly above the bottom bracket to tilt you forward. The head tube will also be short with the armrests and extensions mounted on the top of the base bar being used to dictate the stack. A time trial bike will also typically feature shift levers or buttons, in the age of electronic drivetrains at the end of the time trial extensions, meaning you needn't come out of the aero position every time you wish to change gear.
As we mentioned, TT and triathlon bikes are designed with the sole purpose of minimizing wind resistance and maximising efficiency. At the front, a TT bike will have a base bar where the brake levers are mounted. This also provides support for the arm pads and extensions with the gear shifters at the end. The bike will definitely have a proprietary aero seatpost, and may even have an integrated stem, with some bikes using brand-specific cockpits too.
If it does, you will need to make sure you opt for a frame that has been UCI approved.
