This means any rider ormechanic can easily, quickly, and safely swap out the spider, spindles,and chainrings from one set to another. It also features a built-inchain-line adjustment system so that wider Boost and traditionalnon-Boost configurations can each be accommodated with the samecranksets – so essentially one crankset works across any bike. TheModular system allows for the perfect combination of components,tailoring exact specification requirements to the individual rider andthe type of terrain they're facing.FEATURES:Convertible spider design for different chainring and chainlineconfigurationsHollow carbon composite arms with UD finish30mm forged AL7050 BB392EVO spindleAL7075 100% CNC chainringsChromoly chainring boltsSPECIFICATIONS:Manufacturer: FSAModel: SL-K, Modular, SingleSingle, 32TMass: 628 gramsSpindle type: 30mm, 392 EVOCondition: New in box Note: Length shown in images may differ from what the listing / title /specs may state. Please refer to the written information for specificsregarding length.COMPATIBILITY NOTES:The spindle is a long 30mm type, which means that it's nearlycompatible with all bottom bracket shell types; assuming that the buyerpurchase separately, a 392 EVO bottom bracket made by FSA compatiblewith BOTH their crankset and frame. It is imand portant when choosing abottom bracket, that the buyer understand, measure, and determine whattype of bottom bracket shell they have. It a duty that must beperformed by the buyer for their frame, to understand and measure theirframe themselves to determine compatiiblity since they are inpossession of the frame in question.There is fundamentally not much of a difference between 10 or 11schains. Chains widths are ultimately the deciding factor in determiningcompatibility of the remainder of the drivetrain. For this reason, itis important to understand that cranksets can be compatible either with10 or 11s drivetrains.
