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 4525a is a 45° / 25° bend in aluminum. Performance - The sole purpose of extensions is to provide a comfortable position for the rider's 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 4525a 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 4525a 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 45/25a 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. So it can be used by any rider wishing to improve the comfort of their aerobar grips. - Length: 400mm - Outer Diameter: 22.2mm - Construction: 6061-T6 aluminum, pre-drilled for bar-end shifter cable routing - Weight: 200g/pair

Performance The Airstryke II is intended to allow riders to add aerobars to their road or adventure bike without sacrificing the ability to hold the bars close to the stem.

Fit Data - Armrest Offset: -85mm to 17.5mm in 7.5mm steps - Armrest Width: 131mm to 298mm in 18.5mm steps - Armrest Stack: 40mm Origin As one of the most popular model in the history of aerobars it seemed appropriate to update the much loved Airstryke with our new generation fit range and comfort focused armrest. We didn't want to change the elements that have made the bar so successful and the changes made just enhance the adjustability and comfort. - Bracket: L2 Flip-Up - Clamp Diameter: 31.8mm (26.0 w/Shims) - Armrest: Ergo Armrest - Armrest Stack: 40mm - Reach: -85mm to 17.5mm in 7.5mm steps - Extension Adjustment: 150mm (center of basebar - end) - Armrest Width: 155mm - 203mm - Weight: 592g

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 - Armrest Offset: -70mm to -2.5mm in 7.5mm steps - Armrest Width: 124mm to 290mm in 18.5mm steps (With Extensions at 100mm) - Armrest Stack: 60mm (no riser kit) to 130mm in 5mm increments (With aftermarket Riser Kit) - 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 rider's position or match the position from their previous aerobar or bike. Extensions - 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 35a is a straight 35° bend. - 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
