The new Shimano standard also limits the choice of gradations - only three different ones are currently available. If you are looking for a special combination, you will find it at Specialités TA.
The French specialist for drivetrain components has chainrings in its programme that not only technically match Shimano's own four-hole standard, but also visually integrate well into the design of the crank. The covers, which form the connection to the crank spider, are made of plastic and are available in four colours to match Shimano's Dura-Ace, Ultegra and the silver and black versions of the new 105. The large chainring is available in nine sizes from 42 to 53 teeth, the small one in seven sizes from 33 to 44 teeth, whereby all combinations are possible. A price was not yet available at the trade fair, but will be significantly lower than the original.
