Crazy Deals Shimano XT FC-M8000-B2 Hollowtech II Crankset

XT FC-M8000-B2 crankset by Shimano – chainline three millimetres further out

The Shimano XT FC-M8000-B2 crankset is a variant of the FC-M8000-2 with a chainline that is 3 mm further out. It can therefore only be used in frames with 148 mm rear over locknut dimension. The aluminium crank is equipped with two chainrings in 24-34 or 26-36 tooth increments. It has been optimally tuned with regard to gear ratio and even pedalling rhythm (Dyna-Sys11 technology), whereby the Hollowtech II design with fixed 24 mm axle, which has been tried and tested for many years, ensures a balanced ratio of stiffness and weight.

Note: A chain line 3 mm further out is intended only for hubs with 148 mm over locknut dimension. Shimano B cranks therefore require special frame dimensions with the corresponding cassette position and front derailleur mounting position. Such frames are only compatible with E-Type and Direct Mount derailleurs.

Dyna-Sys11
Dyna-Sys11 is the name of the 11-speed shifting system for MTBs from Shimano. The focus lies on maintaining the pedalling rhythm both on flat ground and on uphill segments. The gear ratios are selected so that you make efficient progress in the most frequently used gear range and do not have to shift gears as much (” Rhythm Step” ).
