ZIPP ROAD HUB TIMELINE
Cognition Hubset (2016- )
COGNITION V1-GEN1 HUBSET (2016-2019)
Wheel Utilized In:
All NSW disc and rim-brake wheels
Zipp’s Cognition disc or rim-brake hubset rolls efficiently whether you are pedaling or coasting. Its Axial Clutch technology allows the freehub’s ratcheting mechanism to deliver half the mechanical drag of conventional three-pawl hubs.
The ultimate in Zipp hub technology
Every time a conventional hubset starts to coast, friction within the freehub ratchet mechanism works like a drum brake to slow the rider down. The drag between the hub shell and driver body during coasting is considered as efficiency loss, especially for road wheels. High drag also can significantly contribute to chain-dropping issues. The drag torque drives the cassette clockwise so the chain gets loose on the load side.
The solution? The rear Cognition™ hub with AxialClutch™ technology reduces drag by disengaging the ratchet mechanism when coasting. It then uses magnets to re-engaged once the rider starts pedaling.

ZIPP ZR1 Hubset (2020- )
Wheel Utilized In:
All Firecrest wheels
In designing an upgraded hubset for our pro-proven Firecrest wheel lineup, we turned to our engineering colleagues at SRAM’s development center in Schweinfurt, Germany. The result is the ZR1 hubsets for disc and rim-brake wheels. This hubset features better seal design for improved durability and quicker response with 66 points of engagement. Our engineers spent more than two years developing the ZR1. Proving the durability of the hubset included more than 58,500km of test riding, part of 3,222 hours of total testing.
The ZR1 features key technology from Zipp’s Cognition hubs. The seal design is the same as the Cognition, with a large dust cap at the base of the driver body and better bearing seals for more protection. The bearing size also is the same as the Cognition, although the Cognition uses a premium bearing. The six pawls are offset to work in two groups of three pawls. At any time, there are always three pawls engaging. This design creates a quick engagement feel, with 66 points of engagement. The driver body is designed so pawls stay in place for disassembly to make service convenient. Zipp hubs are designed to use J-bend spokes, the most popular type of spokes today. J-Bend, widely available, are easier to replace.
Key Benefits
• Better sealing, increasing durability over previous hub model
• Automated Bearing Preload
• Quick engagement for a responsive ride
• Lighter weight than previous hub model
• Same bearing size and caps as premium-level Cognition hub
• e-bike certified
Design Features
• 6 pawls design (2 groups of 3) with individual leaf springs
• Ratchet ring: 33 teeth
• Points of engagement: 66
• Disc brake hub with Center locking rotor interface. The lock ring is included
• Disc and rim brake variants
• Through axles or QR with removable end caps
• XDR or SRAM / Shimano variants
• Campagnolo driver sold separately

ZIPP 188 REAR AND 88 FRONT HUBS (2009-2014)
Zipp 88 V4 Bicycle Wheel Hubs Recall Notice
Zipp 88 V6,V7,V8 Bicycle Wheel Hubs Recall Notice
A completely new design, these hubs have a 17mm axle, pawls with individual leaf springs, 32 teeth ratchet ring, slotted flanges, aero clinch nuts, internal seals and lateral play adjustment. Front end caps are smoke colored with blue/smoke or red rear end caps. Wheel lacing is reversed with 2x drive and radial non-dive spoke pattern. Free hubs are NOT inter-changeable and require a separate conversion kit that includes spacers, seal and matching end cap. The rear end caps on Shimano hubs changed from smoke to red in November 2009.
In May 2010 the 88 front hub spoke retention ring and clinch nut were altered. The spoke retention ring was made thinner, clinch nut diameter enlarged and the boss shape changed. Older version is on the left of the image above.
88/188 – October 2011
Re-design (V7) and improve the current 88/188 hubs with canted, rear, non-drive flange and rear axle changed to accommodate 7.5mm wider non-drive bearing location. Hub are offered in two color options - falcon gray and beyond black across the wheel line, (October 2011).
These changes improve rear 188 hub axle durability and allow 6% stiffer wheels to be built with the same spoke tension. On the 88 front hub, the only change is the color options – the silver and ZedTech hub 88/188 hub versions are discontinued.
Note: the rear 188 hub shell and axle are NOT compatible with the earlier silver version. The bearings (61803) end caps and seals remain unchanged.
Front hubs = 16, 18, 24
Rear hubs = 20, 24
Bearings:
Front = 2 x 61803 (17/26/5)
Rear = 2 x 61803
Free hub = 2 x 61803 (we do not recommend replacing these - very tricky)
JULY 2012
To accommodate Campy11 electronic, we re-machined blue anodized Campagnolo free hubs to remove a small notch at the start of the splines. During July 2012 all available 182 and 188 free hubs were reworked. Going forward new blue Campy11 free hubs will be fully anodized with no silver markings.
2013 NEW ZIPP V8 188 HUB FOR 11 SPEED
In October 2012 a new rear hub version was released to accommodate Shimano11 and Campagnolo 11 speed drive chains. The 188 V7 (2012 gray and black) rear hub was modified as follows:
- Overall drop to drop length (OLD) is increased by 0.8mm
- Axle internal diameter is reduced by 1.0mm (walls are thickened to increase axle strength) (left in image)
- Non-drive side rear end cap is reduced by 1mm, ‘O’ ring removed and colored black (left in image)
- New 11 speed free hub with laser etching, serial number and shim for 10 speed
The V8 88/188 hubs are only available in black, they build a rear wheel which is more durable and marginally stiffer at the same spoke tension. The axle, end cap and free hub are not compatible with the older hub versions (2009-2012). A conversion service is available for only for 2012 188 hubs (gray or black) from Zipp certified wheel builders. The conversion kit is not sold after-market.
November 2012 – revised V6 black rear axle with thicker wall and anno treatment replaces original gray V6 axle. Note the revised axle uses the black end cap and not the red or blue.
In March 2013 the 10 speed ring spacer changed from silver to black in color. This spacer must be inserted first (ahead of the cog set) with the smooth side towards the spokes. The 1.85mm spacer is needed to run 9 or 10 speed Shimano or SRAM cogs with the 11 speed free hub.
July 2013 - Disc Brake Hub
We introduced the 303 Firecrest disc brake wheel set with new front and rear black Zipp disc brake hubs, 24/24 spokes 100mm front and 135mm rear spacing. Note the spoke angles for disc brake wheels are different (lower angles) than regular road brake wheels and the lacing pattern is 1x, 1x front and 2x,2x on the rear.
Bearings:
Rear hub – 61903 x 2
Free hub – 61803 x 2
Front hub - 61803 x 2
2014 V9 rear hub
In September 2013 we released a stronger and more durable revised 188 rear hub. Larger 2 x 61903 hub bearings, wider non-drive flange, virtual 3x cross lacing on drive and non-drive sides. Front hub remains unchanged (V7).
2014 V9 88 front hub
The Zipp 88 front hub received an in-line change (February 2014) to increase durability & performance. The retaining ring that was previously used has been elimated and the spoke slot depth increased. We made a similar design change to the rear 188 V9 last Fall. This front hub change does not affect spoke length, price, part numbers or function.
ZIPP TRADITIONAL 208 REAR AND 108 FRONT HUBS (2006-2009)
This hub set uses Hi / Lo rear flange geometry (58/47mm) to increase lateral and torsional stiffness. Has colored free hub bodies and may be laced radially. During 2009 this hub was used in the team issue wheels only.
Front hub = 20, 28, 32 holes

ZIPP TRADITIONAL 220 REAR AND 95 FRONT HUBS (2004-2006)
A silver polished Al alloy hub body matched to traditional hub flanges and silver free-hub body distinguish this hub. Like the 84/202 hub set, these hubs also have the carbon dust caps, held on with a rubber retaining ring. Most of the internals are interchangeable with the 84/202. Available in 28 and 32 holes. Call for information concerning compatibility between the two hubs. Status: discontinued, contact ZIPP customer service for replacement parts.
ZIPP 202 REAR and 84 FRONT hubs (2002-2005)
Al alloy silver polished hub bodies, most easily recognized by carbon weave protective end caps on both front and rear hubs. Available for either Shimano or Campagnolo, the bodies are interchangeable, but are not compatible with earlier models due to over-sized 15mm axle on the 202 rear and 84 front hubs.
There are 2 versions of the silver free hub body for this hub model. The 202W free hub has a solid silver ring on the free hub side adjoining the pawls, while the 202P has grooves that are machined all the way through with a slight 'lip' at the end of each spline.
Status discontinued (2012), spare parts (e.g. axles and non-drive end caps) may not be available or will be very hard to find.

Front hub = 2 x 61802 (15/24/5)
Rear hub body = 1 x 61802 1 x 61902 (15/28/7)
Free hub = 2 x 61802 (we do not recommend replacing these - very tricky)
ZIPP 282 REAR AND 102 FRONT HUBS (1999-2001)
The 102 front and 282 rear hubs are an ideal combination of performance, weight, durability, and value. Recognizable from other ZIPP hubs by their black anodized all aluminum hub construction; the 102 and 282 are available for both Shimano 8/9 speed and Campagnolo 9/10 speed systems. The 102 and 282 are the first ZIPP hubs to utilize butted or oval straight pull spokes. Free-hub bodies are interchangeable. Both front and rear hubs turn on the highest quality industrial cartridge bearings available. These bearings were used in a number of subsequent ZIPP wheel sets. If you need parts for the 2 pawl earlier 282 hub (shown above - often called the Swiss version), you must change axle, end caps and free-hub to upgrade to the 3 pawl (USA) model. Hub maintenance notes. Status: discontinued, parts are difficult to find.
Bearings:
Front = 2 x 61900
Rear = 1 x 6901 2RS, 1 x 6001 2RS
Free hub = 2 x 6901 2RS (we do not recommend replacing these - very tricky)
Note: early 282 hubs may be silver. When interchanging free hub bodies, check to see if the existing hub uses two or three pawls in the engagement mechanism and check bearing seal color.
In mid-2001 a 'USA' built version of the 282 was introduced. It is laser etched in the center of the hub flange with "USA" in silver on the black hub shell. Free-hub bodies are not inter-changeable between earlier 'swiss' versions and the usa version (shown on left). Model 102 front: flange diameter = 23mm, center to flange = 39mm. Model 282 rear free hub: drive side flange = 51mm, non-drive flange = 33.5mm, center to drive side flange = 12mm, center to non-drive flange = 35mm. Maintenance notes.
Free hub bodies: 'USA' have blue bearings seals, 'Swiss' has black bearing seals - not inter-changeable.
Bearings:
Front = 2 x 6900-2RS
Rear = non-drive 1 x 6901 RS, drive= 60012RS
Free hub = 2 x 6901RS (we do not recommend replacing these - very tricky)
ZIPP 377 REAR and 182 FRONT HUBS (1998)
The 182 front and 377 rear hub set are designed to offer a more traditional hub mechanism with a combination of performance, weight, durability, and value. This hub set is recognizable from other ZIPP hubs by its all aluminum hub shell construction and distinctive hour-glass hub body . This hub series used 6001 2RS bearings. The hubs are anodized Smoke/Silver Gray with a laser etched ZIPP logo. Shimano 8 and 9 speed compatible. Complete service information is available by contacting ZIPP Technical and Customer Service.
ZIPP 217 REAR AND 100 FRONT HUBS (1995-1999)
The 217 and 100 front are recognized by their narrow carbon fiber center sections and Smoke/Silver Gray laser ZIPP logo etched flanges. The 217 is an extremely light high performance rear hub, with an average weight of 220 grams and used R6 bearings. The free hub body is Stainless Steel. To achieve its lightweight without sacrificing durability, the 217 free-hub body rotates on two non-contact bushings rather than traditional ball or cartridge bearings. The free hub mechanism is very simple and reliable. Remember, however, that the free-hub body is essentially "floating" on a thin film of lubricant across the surfaces of the bushings.
The free-hub body must be lubricated every 300-500 miles. Look at the back of the drive-side flange for the lubrication port. Lubricant is injected through this port while holding the free hub body facing downward and rotating the mechanism. It is essential to use only specially formulated Zipp Lube or Zipp recommended lubricants. Any other lubricant will almost certainly cause the hub mechanism to malfunction!. The 217 rear hub is available in Shimano 8 and 9 speed compatible free hubs as well as Campagnolo compatible 8 speed free hubs. Note the free hubs look very similar - the Campy has one wider spline. Technical data: weight = 223gm, spacing = 130mm (8sp), flange diameter = 43mm, center to drive = 19mm, center to non-drive = 36mm. Bearings model 100 = 2 x R6. Model 217 = 2 x R6. The free hub body needs a special bearing cup removal tool to disassemble. Status discontinued
ZIPP 145 MTB. FRONT SUSPENSION HUB (1995-1997)
A front hub designed for mtb. applications with front suspension, the ZIPP 145 was rated the stiffest suspension hub available by VeloNews. This hub is recognized by the large diameter carbon fiber center section and by the grease injection ports on each hub flange. Hub flanges are anodized Smoke/Silver Gray with a laser etched ZIPP logo.
Note: Remove the outer end cap and seals before injecting new grease. Use regular bearing grease. Hub also features 19mm hollow over-sized axle and over-sized 6092 bearings with an auxiliary seal. Status: Discontinued please contact ZIPP Speed Weaponry for Service information.
ZIPP 295 REAR AND 104 FRONT HUBS (1993-1995)
The 295 and 104 retain the large diameter carbon fiber center section of original Ballistic hub set, but are anodized a Smoke/Silver Gray color. This hub set is a refinement of the original Ballistic hub concept and still used R6 bearings. All internal parts are interchangeable with the original Ballistic hub models except for the end caps. The 295 rear was also available in 7 or 8 speed freewheel models as well as a Shimano 8 speed free hub (shown here). Not available in Campagnolo style Status: Discontinued. Please contact ZIPP Speed Weaponry for service information.
ZIPP BALLISTIC (1992-1993)
The original ZIPP hub, the Ballistic front and rear hub set is identified by gold anodized hub flanges and large diameter carbon fiber center section. The Ballistic rear hub was available in 7 and 8 speed freewheel models (left) as well as a Shimano compatible 8-speed free hub (right). Flange diameter is 43mm (both types), for free hub type: center to flange front = 35mm, center to drive 19mm center to non-drive = 36mm front = 110gm rear cassette = 305gm. This hub model incorporated a wave spring preload system and used R6 bearings. Note the black free hub body with threads on the end, only available in Shimano style. Status: Discontinued.
