Shimano is still not completely falling for the single-chainring hype, but is indirectly paying tribute to the death of the front derailleur initiated by Sram: the new XTR no longer offers a triple crank. The marathon rider - or the rider who doesn't want to leave it at the bandwidth of a single-chainring solution - can ride a 38/28 double crank and thus obtain closely spaced gears that can be used to suit the load. The small chainring is bolted to the large chainring, while the large chainring is connected to the crank using the direct mount method. If the crank is to be used using the single chainring method, the small chainring can be easily removed.

Shimano has developed a new shift lever for shifting on the front derailleur. This is called Rapidfire Plus Mono, upshifting and downshifting is done with just one lever.
