This is an updated version of the Oversized Pulley Wheel System for Shimano 9100/9150 and 8000 SS/8050 SS. This new design has an integrated stop tower for easier mounting.
The CeramicSpeed Oversized Pulley Wheels System has been proven to be the fastest pulley system in the world, providing energy savings starting at 2.4 watts compared to standard Shimano systems.
The OSPW System for Shimano 9100/9150 and 8000 SS/8050 SS is an industry-leading product, chosen by many of the world's leading cycling teams and professional triathletes.
It features a 13-tooth upper pulley wheel and a 19-tooth lower to provide absolute optimization of the rear derailleur, and these oversized aluminum pulley wheels come fitted with either standard or coated CeramicSpeed Bearings: your choice.
The Shimano 9100/8000 OSPW system is compatible up to a 32 tooth cassette for both Dura Ace & Ultegra derailleurs
The typical overall power savings of the OSPW System for Shimano 9100/9150/8000 is 30%-60% over a stock setup.
The oversized pulley wheels have lifespan that is 3-5 times longer than the commonly used standard pulleys on the market.
Please note: The OSPW System for 9100/9150 and 8000 SS/8050 SS is NOT compatible with Ultegra 8000-GS or 8050-GS (medium cage) derailleurs, nor with the clutch-equipped Ultegra RD RX800 & RX805. Choose CeramicSpeed's OSPW X for Shimano RX800/805 for a compatible RX800 & RX805 version. For a compatible upgrade for Ultegra 8000-GS or 8050-GS choose their Pulley Wheels for Shimano, 11s NW.
In The Box:
- A complete 13-tooth/19-tooth OSPW System
- CeramicSpeed Bearing Oil in 15ml dropper bottle

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

The Airstryke II takes the features of the ever popular Airstryke and adds an expanded fit range and more comfortable armrest. The flip up bracket and classic shape are retained.
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. The comfortable grip angle and smoothly curved armrest offer a relaxed position for long days in the saddle.
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
