The new range of extensions have evolved from our well proven T-Series. They have been designed to offer distinct fit options. We have also adopted a new naming system whereby the name gives the angle material of the extension. Thus 35c is a 35° bend in aluminum. Performance - The sole purpose of extensions is to provide a comfortable position for the riders hands relative to the armrests. They enhance performance by allowing the rider to relax into their optimal position. Which is why we provide different fit options so each rider can chase their best performance. Fit Data - Extension Shape: A 35 degree ski-bend extension suited to riders who prefer to adopt a wrist angle that is on the low side of the neutral range. - The 35c is a straight 35° bend. Tech Guide - All the extensions have a 22.2mm diameter in the clamping area. - They are designed for cables to be routed out the rear of the extensions so do not have cable exit holes. Who is it for? - The extensions will fit in any aerobar that is designed for 22.2mm. So can be used by any rider wishing to improve the comfort of their aerobar grips. - Length: 400mm - Outer Diameter: 22.2mm - Construction: Carbon - Weight: 262g/pair

The new range of extensions have evolved from our well proven T-Series. They have been designed to offer distinct fit options. We have also adopted a new naming system whereby the name gives the angle material of the extension. Thus 45/25c is a 45° / 25° bend in aluminum. Performance - The sole purpose of extensions is to provide a comfortable position for the riders hands relative to the armrests. They enhance performance by allowing the rider to relax into their optimal position. Which is why we provide different fit options so each rider can chase their best performance. Fit Data - The 45/25c extensions have a first section at 45° and the grip at 25°. The rider can choose whether to hold high for the shrugged position or low for a more open, head up position. - The 45/25a offer a 7.5mm lateral shift per side. This allows the rider to get their hands narrower or wider without tilting the extensions so much that the shifters touch. Origin - Recent trends in aerobar fit have been towards higher hand positions, so we've increased the rise compared to previous generation extensions. We have focused on the most popular angles from our previous range and added the 45/25c as a multi position option. Tech Guide - All the extensions have a 22.2mm diameter in the clamping area. - They are designed for cables to be routed out the rear of the extensions so do not have cable exit holes. Who is it for? - The extensions will fit in any aerobar that is designed for 22.2mm.

Our new Sonic bracket has been designed as the successor to the J2, which has been a somewhat ignored part of our range. With this update, it brings our new generation fit range to a wider range of price points, replacing the J2 bracket. The Ergo armrest has been created to offer both a huge upgrade in fit range as well as increased rider comfort with a supportive curve to cup the arms. Performance - The Sonic/Ergo is designed to present minimal frontal area to create as little aerodynamic drag as possible. The main purpose of an aerobar is, of course, to get the rider into a fast position. Despite a fairly minimalist appearance, the Sonic/Ergo offers a comprehensive fit range for exactly this purpose. Fit Data - The extension length and rotation can be easily adjusted using the top bolt. There are 100 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1500 possible configurations. As a clip-on bar it is also possible to adjust the extension width and tilt easily. This is the most adjustable clip-on bar on the market (and in history). It is worth noting that our previous top level clip-on aerobar, the J4/F35, offered 90 possible configurations. This highlights the significant step forward we’ve made with our new generation aerobars in allowing riders to precisely adjust their position. Origin - After we released the Supersonic (J5) as a premium bracket with market-leading fit options and versatility, we wanted to bring the same kind of options to the rest of our range of brackets and thus aerobars. By simplifying the extension clamp and shifting the wing forward to the bar center line, we were able to meet our targets. As a consequence of the simplification the Sonic is the lightest of our current brackets. The Ergo armrest shares the flippable design of the rest of our new generation armrests. By swapping sides or rotating the armrests smaller increments of movement are achieved – making it simple to fine tune a riders position or match the position from their previous aerobar or bike. - Bracket: Sonic - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Ergo / 10mm Pads - Armrest Width: 124mm to 290mm in 18.5mm steps (with Extensions at 100mm) - Armrest Offset: -70mm to -2.5mm in 7.5mm steps - Armrest Stack: The minimum is 60mm and the bracket is compatible with our existing risers which add up to 130mm stack with (70mm of spacers added) - Weight: 559g

The Subsonic/Race/35a aerobar combines the low stack Subsonic bracket with the arm-hugging Race armrest to offer an industry-leading fit range oriented towards low, narrow positions. The 35a extension offers a comfortable 35 degree angle with a 80mm rise. This is the only low stack clip-on in the market that maintains the pad-to-grip angle as the bar is stacked up Subsonic is not just another aerobar bracket. It brings our next-generation fit range to a low stack bracket design. This allows the bar to use our riser kits to increase the stack without changing the relationship between the armrest and the grips. The Race armrest has been designed to tightly cup the riders arms – facilitating a narrow position and increasing control at speed. Performance - The Subsonic/Race is designed to achieve a lower stack height than standard aerobars, without the added frontal area of a below-the-basebar extension clamping system. This improves aerodynamics and the fit range. Fit Data - Armrest offset: -85mm to -17.5mm in 7.5mm steps - Armrest Width: 142mm to 272mm in 18.5mm steps (with Extensions at 100mm) - Armrest Stack: The minimum is 40mm and the bracket is compatible with our existing risers which add up to 70mm of stack in 5mm increments. - The extension rotation can be easily adjusted using the shaft bolt. There is a 40mm range of extension length adjustment once the extensions have been cut. There are 80 distinct position options achievable just by moving the armrests. Combine that with the risers and this bar offers 1200 possible configurations. As a clip on bar it is also possible to adjust the extension width and tilt easily. This is the most adjustable low stack clip-on on the market. Origin Story After we released the Supersonic (J5) as a premium bracket with market leading fit options and verstility we wanted to bring the same kind of options to teh rest of our range of brackets and thus aerobars. Where our supersonic and Sonic brackets have a minimum stack of around 60mm, like most of the popular aerobars - we wanted the Subsonic to offer a substantially lower position. This helps the segment of the market who struggle to get into their ideal position with modern bike frames. And it was vital that we include stack height adjustment without altering the pad grip relationship - so our riders have the ability to fine-tune every aspect of their setup. The Race armrest shares the flippable design of the rest of our new generation armrests. By swapping sides or rotating the armrest, smaller increments of movement are achieved - making it simple to fine-tune a rider's position or match the position from their previous aerobar or bike. Additionally, there are two thicknesses of cushion available to ensure a snug fit for different sized arms. Who is it for - This bar is perfect for riders who wish to achieve lower positions than are possible with standard aerobar designs. Unlike other low stack bars, it allows fine-tuning of the stack height so the rider is not limited to only one armpad height. With the Race armrests fitted, it is tailored towards riders who intend to be low and narrow to punch the smallest possible hole through the wind. - Bracket: Subsonic - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Race / 5mm Pads - Extension Length: 350mm - Width: 142mm to 272mm - Weight: 590g
