The 39a extension provides a comfortable 39-degree angle with an 87mm rise. This is the only low stack clip-on aerobar on the market that maintains the pad-to-grip angle as the bar is stacked up.\u003c\/li\u003e\n\u003cli\u003eSubsonic 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 stack height without changing the relationship between the armrest and the grips.\u003c\/li\u003e\n\u003cli\u003eThe Ergo armrest is designed to tightly cup the rider???s arms, facilitating a narrow position and increasing control at speed.\u003c\/li\u003e\n\u003cli\u003ePerformance\u003c\/li\u003e\n\u003cli\u003eThe Subsonic\/Ergo 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 both aerodynamics and fit range.\u003c\/li\u003e\n\u003cli\u003eFit Data\u003c\/li\u003e\n\u003cli\u003eArmrest Offset: -85mm to -17.5mm in 7.5mm steps\u003c\/li\u003e\n\u003cli\u003eArmrest Width: 142mm to 272mm in 18.5mm steps (with extensions at 100mm)\u003c\/li\u003e\n\u003cli\u003eArmrest Stack: Minimum 40mm. Compatible with existing risers adding up to 70mm of stack in 5mm increments.\u003c\/li\u003e\n\u003cli\u003eThe 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.\u003c\/li\u003e\n\u003cli\u003eThere are 80 distinct position options achievable by moving the armrests alone. When combined with risers, this bar offers 1200 possible configurations. As a clip-on bar, extension width and tilt can also be adjusted easily, making this the most adjustable low stack clip-on on the market.\u003c\/li\u003e\n\u003cli\u003eOrigin Story\u003c\/li\u003e\n\u003cli\u003eAfter releasing the Supersonic (J5) as a premium bracket with market-leading fit options and versatility, we wanted to bring the same level of adjustability to the rest of our aerobar range.\u003c\/li\u003e\n\u003cli\u003eWhere the Supersonic and Sonic brackets have a minimum stack of around 60mm, similar to most popular aerobars, the Subsonic was designed to offer a substantially lower position. This helps riders who struggle to achieve their ideal fit on modern bike frames.\u003c\/li\u003e\n\u003cli\u003eIt was vital to include stack height adjustment without altering the pad-to-grip relationship, allowing riders to fine-tune every aspect of their setup.\u003c\/li\u003e\n\u003cli\u003eThe Ergo armrest shares the flippable design of our new generation armrests. By swapping sides or rotating the armrests, smaller increments of movement are achieved, making it easy to fine-tune a rider???s position or replicate a previous setup.\u003c\/li\u003e\n\u003cli\u003eWho Is It For\u003c\/li\u003e\n\u003cli\u003eThis bar is ideal for riders seeking lower positions than those possible with standard aerobar designs. Unlike other low stack bars, it allows fine-tuning of stack height so riders are not limited to a single armrest height.\u003c\/li\u003e\n\u003cli\u003eWith Race armrests fitted, it is tailored for riders aiming to be low and narrow to punch the smallest possible hole through the wind.\u003c\/li\u003e\n\u003cli\u003eTech Specs\u003c\/li\u003e\n\u003cli\u003eBracket: Subsonic\u003c\/li\u003e\n\u003cli\u003eClamp Diameter: 31.8mm (26.0mm with Shim Kit, sold separately)\u003c\/li\u003e\n\u003cli\u003eArmrest: Ergo \/ 10mm Pads\u003c\/li\u003e\n\u003cli\u003eExtension Length: 340mm\u003c\/li\u003e\n\u003cli\u003eWidth: 142mm to 272mm\u003c\/li\u003e\n\u003cli\u003eWeight: 590g\u003c\/li\u003e\n\u003cli\u003eColor: Black\u003c\/li\u003e\n\u003cli\u003eTech Guide\u003c\/li\u003e\n\u003cli\u003eTorque Settings\u003c\/li\u003e\n\u003cli\u003eBar Clamp: 6Nm\u003c\/li\u003e\n\u003cli\u003eExtension Clamp: 5Nm\u003c\/li\u003e\n\u003cli\u003eArmrest Bolts: 4.7Nm\u003c\/li\u003e\n\u003cli\u003eWeight Breakdown\u003c\/li\u003e\n\u003cli\u003eBracket: 304g\u003c\/li\u003e\n\u003cli\u003eArmrest: 148g\u003c\/li\u003e\n\u003cli\u003eExtensions: 186g\u003c\/li\u003e\n\u003cli\u003eTotal: 590g\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eProduct code: PRSSNC3.\u003c\/p\u003e","brand":"Freewheel \/ Madison","offers":[{"title":"Default Title","offer_id":55543669227862,"sku":"PRSSNC3","price":189.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0801\/1425\/4166\/files\/ftp_f_freewheel_imagesmadisonfwaccessoriesprssnc3_01.jpg?v=1790787206","url":"https:\/\/substancecycles.co.uk\/products\/freewheel-prssnc3","provider":"Substance Cycles","version":"1.0","type":"link"}
