In the UK time trialling is a popular sport, however in the rest of the world it is much more niche. Consequently, the market for Triathlon bikes is much larger than that for TT specific bikes.
The best time trial bikes are primarily designed for use by professional riders competing in WorldTour bike races such as the Tour de France. Races such as the Tour fall under the jurisdiction of the UCI and have to convene to the rules of that governing body.
The UCI rules and regulations dictate tube shapes, frame design and geometry. UCI legal bikes have to conform to the classic bike frame design of two triangles and the other rules stipulating what can and can't go on a bike, not that brands haven't questioned the balance between clarity and ambiguity of the rules. The rules and regulations for the best triathlon bikes are much more relaxed than that laid out by the UCI and the result is that riders can adopt more aggressive positions and bike design can be more radical.
A great example is the Cervelo P5X. If your wondering where to start, our page dedicated to everything you need to get into triathlon will help and guide you in to the sport.
A notable exception to this would be the National Time Trial championships. The best entry level time trial bikes will usually come with a good quality aluminium frame and mid tier groupset such as Shimano Wheels are likely to be non aero, although some brands will supply entry level deep sections, although you can always upgrade at a later date to a pair of the best road bike wheels. They will feature less integration than the much more expensive top end models and this results in the frame being slightly less aerodynamic.
However, this is usually less than you would think, often in the region of just six watts. Although the bike was made up of used parts, it demonstrates that the difference between top end frame sets and entry level is aerodynamically small. The best mid point time trail bikes are likely to be carbon and you will likely start to see some integration. Integration involves specially shaped parts and components that help streamline the package.
Groupsets are likely to mid level, such as Shimano Ultegra mechanical and Di2. At the highest end of the market are the best time trial bikes and will be mirror images of those used by professional athletes and serious amateurs. Expect to see lots of exotic looking tube shapes, especially if looking at a non UCI legal time trial bike, designed especially in the most effective way to cheat the wind. The top end time trial bikes will also be slightly more aerodynamic than mid price machines, although taking just the frameset into consideration this is only likely to be handful of watts, and the vast majority of the savings will be in the design or choice of components the bike is equipped with.
To a competitive rider, where every watt counts this can be significant though. Electronic groupsets are often found on top end models. Another option is the BMC Timemachine. The former features a 'v cockpit' which lifts the stack height and is more suited to triathletes. The TM01 also has a hinged fork, to allow for easy brake pad swapping when alternating between aluminium training wheels and carbon race wheels.
With the additional v cockpit and fairings, such as the storage box, the Timemachine is not UCI legal, which is worth bearing in mind. Generally speaking, the deeper the wheel the faster it will be, with a rear disc being the preferred option for top time trialists. Time trial bikes are not often sold with disc, or optimum race wheels. If buying a complete bike we would suggest a bike with some decent wheels that can become your training hoops. You can invest further down the line in some faster wheels.
It is worth budgeting for fast wheels as many experts suggest they offer more of an aerodynamic advantage than the frame. Regarding which wheel type is fastest tubulars, clinchers and tubeless , we have a video you can watch here. If most of your racing is likely to be flat, then the slight weight saving of a premium groupset is not going to be hugely significant.
If you are looking to save money without a loss in performance then equip the best time trial bike you can afford with a slightly lower specced road bike groupset. That said, electronic groupsets are useful because they are easier to set up and maintain - something advantageous on very aero frames, with complicated cable routing. Black Blue 2.

Sign In It looks like you've already got an account! Cables run inside the handlebar and down through the stem directly into the frame. The relatively broad top tube helps keep the front triangle from twisting under load.
The articulating front brake is nearly seamlessly integrated into the fork crown. Rubber plugs mark the pivot points and the tops of arms are just barely peeking out out of the frame surface. The rear brake is built right into the chain stays and the guts are tucked cleanly away behind an access plate. The compact rear triangle stiffens things up and also presents less frontal area. The seatpost clamp mechanism is virtually invisible.
The integrated DuoTrap wireless transmitter picks up speed and cadence information with only a minimal effect on airflow. The stout front derailleur braze-on has a large surface area for bonding and is also reinforced at the top and bottom edge to resist bending during shifts. The aluminium fork tips already include safety tabs. Think the Speed Concept is just a one-off? Think again. According to trek, the kamm tail truncated airfoil second from right behaves identically to a full cross-section far right and markedly better than a section second from left , especially at higher yaw angles.
Time trial bikes are all about stiffness and aerodynamics so the speed concept is fitted with giant chain stays to help put the power down.
