Shimano Dura-Ace WH-9000-C35-CL Wheelset
Virtually every performance oriented rider likes a light, dependable wheel set. And if you can get an aero profile while keeping the weight below 1500 grams - even better. The rims on the WH-9000-C35-CL wheels have a 35mm profile which if perfect for riders leery of deep section rims but wanting an aero benefit. The lower rim weight also comes into play in booting acceleration and climbing performance.
Shimano uses a proprietary, in-house construction where carbon is lamented to a thin aluminum rim. You then get the best of both worlds. The carbon portion is light and stiff does an excellent job of dampening the ride while enhancing the strength of rim at the same time. The alloy braking surface is far superior to carbon and is incredibly durable. Extra carbon is located around areas of stress such as the spoke holes for season after season durability.
The WH-9000-C35-CL is 11-speed compatible and comes with a 1.85mm spacer so it will work with 10, 9, 8-speed and SRAM too. Other differences over the WH-7900 wheels include improved hub flanges that are 7mm wider for increased strength and a now 100% titanium freehub body for lower weight. Styling is a bit sharper with a new black anodized hub finish, black spokes and nipples and a glossier finish on the rim.
The hubs are based on Dura-Ace design featuring angular contact bearing and labyrinth seals, however vary a bit by offering straight pull spokes and a wider stance for the spokes. The flanges are super wide increasing the distance of the spokes between the flange creating a wider footprint for a far stronger and more stable wheel. The spokes are bladed and the nipples are the standard Shimano black alloy variety. The front wheel is 16 hole with a radial lace, while the rear is 21 hole with a OptBal 2:1 lacing meaning there are 14 spokes on the drive side and 7 on the non-drive to enhance rigidity and durability. OptBal balances spoke tension meaning no spoke breakage and wheels that seldom need truing. If truing is required, the nipples are external at the rim for easy access.
In terms of how the wheels ride, we would have to say 2 words that comes to mind are fast and responsive. You also get a particular amount of built in durability and longevity with the hubs, because of the design - they will last many seasons with no required maintenance. They offer a pair of the best skewers in the business and over the past few years this carbon-hybrid rim design has proven to be as durable as anything else currently on the market. Includes skewers, rim tape, spoke wrenches and wheel bags.
