absoluteBLACK Oval 110BCD 4/5 Hole FSA Inner Chainring

Designed to work with FSA cranks that use 4 or 5 hole 110BCD asymmetric mounting configurations, this inner chainring has an oval shape to help the rider pedal with more efficiency and comfort. Despite only having four holes, this chainring is also fully compatible with FSA cranks that use a fifth hidden bolt, as this isn’t necessary for completely effective installation. Made from durable and stiff 7075 aluminium, excellent power transfer is guaranteed, even during the fastest sprints.

Includes

  • 1 x chainring

Compatibility

  • Chainring setup: Double
  • Mounting format: 4 hole, 110BCD asymmetric. Also fits FSA 5 hole cranks that use a fifth hidden bolt
  • Cranks: All FSA ABS (asymmetric bolt spacing) cranks like Gossamer, SL-K, K-Force, K-Force Light. Both 4 and 5 bolt versions. One model fits them all. ABS cranks only. Di2 Compatible
  • Chains: 10, 11 and 12-speed

Important

  • For Gossamer cranks - use original FSA bolts and spacers. There is nothing else needed to mount these rings
  • For SL-K - use original FSA bolt covers and bolts. These will fit perfectly. There is nothing else needed to mount these rings
  • For K-Force - use absoluteBLACK bolt covers (available separately). This is absolutely necessary as you will not be able to mount these chainrings to K-Force cranks otherwise
  • The different sizes of this inner chainring are designed specifically for the following outer/inner chainring combinations: 50/34, 52/36, 52/38, 53/39T
  • If you wish to use other configurations this chainring will still work, but gear shifting will be slower and more adjustments of the front derailleur may be needed in order to make it acceptable. Also remember that the front derailleur can only accept a maximum 16-tooth difference between two chainrings - this is how Shimano and SRAM designed them
  • absoluteBLACK recommends to always use a new chain with a new chainring

Features

  • A premium quality inner chainring for FSA cranks that use a 110BCD 4 or 5 hole asymmetric mounting format
  • Made from strong, stiff and durable CNC machined 7075 aluminium
  • A special oval shape specifically places the peak of the oval at 110.5° - 116.3° after top dead centre
  • The oval shape maximises the part of the pedal stroke where power is produced and minimises resistance where it isn’t
  • More pedalling efficiency and smoothness is promoted by the oval format, reducing oxygen consumption and fatigue
  • Reduced stress on the knees is another benefit of the oval shape
  • 4 hole, 110BCD mounting format that also works with 5 hole FSA systems that use a 5th hidden bolt
  • Optimised for 10, 11 and 12-speed drivetrains
  • Manufacturer claimed weight: 34-tooth - 32 grams, 36-tooth - 33 grams, 38-tooth - 38 grams, 39-tooth - 41 grams
