Description

BLACKseries by ABSOLUTE BLACK chainring oval 1-fold LK 104 | 4-hole narrow wide black

The ultimate solution for Shimano and other cranks based on the 104 mm bolt bolt circle diameter diameter. If you've ever thought about installing a 1x9 / 1x10 / 1x11 / 1x12 drive and are wondering how to solve the chain guide problem, then here is the answer.
BLACKseries chainrings have special teeth that prevent the chain from jumping off. The principle follows that of the SRAM XX1 chainrings. In conjunction with a SRAM Type2 / 3 or Shimano Shadow + rear derailleur, which have a greatly increased cage preload, the chain is reliably held in position even without a chain guide.

oval chainrings
The ovalization of the chainring increases performance and traction off-road by varying the drive train and optimizing the resistance. When pedaling, natural strengths and weaknesses are brought into harmony. In this way, better use of the stronger muscle groups is achieved and a balance is created in the weaker muscles on the way to work (lower stroke).

about BLACKseries
BLACKseries is a sister company of absoluteBLACK Ltd. It was founded out of the desire to be able to offer an alternative to the ultra-modern products from absoluteBLACK.
BLACKseries products use the same raw materials, manufacturing processes, quality controls and tooth profiling as absoluteBLACK. The difference lies in the overall industrial design, which saves a lot of time for CNC machining and thus makes the products more attractively priced for the end customer.
