ZIPP 188 REAR AND 88 FRONT HUBS (2009-2014)
Zipp 88 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
Front = 2 x 61803 (17/26/5)
Rear = 2 x 61803
Free hub = 2 x 61803 (we do not recommend replacing these - very tricky)
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.
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.
