According to this study, an aero water bottle can save 1.6 to 3.9 Watts compared to a normal 500mL water bottle mounted on the downtube. However, the benefits are negligible below 19mph (30km/h). The true benefits only show if you ride at 25mph (40km/h) or above. Fork: SuperSix EVO Carbon, integrated crown race, 12x100mm Syntace thru-axle, flat mount disc, internal routing, 1-1/8″ to 1-1/4″ Delta steerer, 55mm offset (51-54cm), 45mm offset (56-61cm) Aero bottles are banned under UCI regulation since 2013. Bottles can only be located inside of the frame: on the down and seat tubes. The dimensions of the bottles are regulated: 4 to 10cm in cross-section and 400mL to 800mL in capacity. Integrated water bottles are also forbidden by the UCI. What ultimately seals the victory is the fact that this hydration system is about 50% lighter than the Profile Designs option.

A better location was the seat tube - only resulting in a 3.6w penalty at 40kph or 1.6w at 30kph (1min30sec over an IM bike leg).I believe the UCI regulation is question is that –‘bottles themselves must not exceed maximum cross-section dimensions of 10cm or less than 4cm.’ Aero bottles are a great place to store concentrated nutrition. Swap to a standard cage for longer training rides. The cage is longer than your typical water bottle cage. Fortunately, it comes with quite a degree of flexibility where you place it on the down tube (or seat tube) For one, this hydration system can support up to 2 bottles but is just as effective and aerodynamic when supporting only one.

This hydration system also features an aerodynamic profile with a slip-free design so you do not have to worry about slowing down. This is also one of the larger frame mounted systems with a capacity of 24 oz and a bottle made of BPA-free plastic. Finally, this hydration system maximizes its design with an aerodynamic profile as well as a non-slip grip. Time trial bikes are typically designed for high-speed, straight-line stability. Road racing bikes, on the other hand, need to feel nimble and versatile. Bottles shall not be integrated to the frame and may only be located on the down and seat tubes on the inside of the frame. The dimensions of the cross sections of a bottle used in competition must not exceed 10 cm or be less than 4 cm and their capacity must be a minimum of 400 ml and a maximum of 800 ml.“ This allows you to get a great price on a carbon fiber cage mounted to the frame, though it is not especially secure or durable. Reasonably Decent

Anyone. Anywhere. Anytime.

Time gain per type of hydration system over the length of an Ironman distance in comparison with standard 500mL bottle fixed on the downtube

Considering that their products are top-notch no matter what decision you make, it should only make sense that we include one such component that is featured on one of their larger systems. The Aero TT impresses us most with the inclusion of a carbon fiber cage that is less likely to deal with some of the durability issues other carbon fiber cages demonstrate because of its frame mounted position. Cage – This is a far simpler form of bike hydration system though it will inherently require more effort on your end to use. Basically, the cage type of triathlon fueling systems merely hold whatever receptacle in place but do not aid or assist the transfer of water in any way. This means that cage systems do not have a feeder tube or any other automatic method of distribution. However, this also means that the cage type of hydration systems are much easier to refill as you can just grab another bottle. One issue is that cage systems do not always hold the bottle securely and can allow it to topple out of the cage if you ride over rougher terrain. Mount Though this may sound surprising (received wisdom is weight matters above all else on climbs), the tide may be turning in our understanding of what actually slows road cyclists down.

Cannondale partnered up with Italian brand MOMO Design from the motor industry to develop their new one-piece integrated handlebar. Orbea’s testing showed the relationship between adding weight to a bike, versus the extra power required to overcome that additional mass on various gradients. Orbea Indeed, according to simulations by Swiss Side, a pure aero road bike with clincher or tubeless tyres may have been the fastest bike setup for Stage 11 of the 2021 Tour de France, which included two ascents of Mont Ventoux.
