Product details


GARBARUK Chainring Melon oval 1-way narrow-wide LK 110 mm Shimano FC-R9100 asymmetric

Garbaruk is a company from Ukraine, which has its roots in motorsport.
The design and manufacture of tuning parts for engines and chassis were part of the Garbaruk company's hobby. The experience gained and the knowledge that the cycling enthusiasts Garbaruk brothers use today in the production of bicycle parts. All steps from design, production to surface finishing take place under one roof.
7075-T6 aluminum from Germany is the raw material from which the chainrings of Garbaruk are elaborately CNC-milled. The chainrings have some features that are different from competitors.

narrow-wide teeth
In order to hold the chain securely in position even without chain guide, the teeth have a special profile of narrow and wide teeth in alternation. To ensure that this is even under very rough and rough conditions, the teeth of Garbaruk chainrings are made about 40% longer than conventional teeth. Furthermore, the teeth are shaped so that even in muddy conditions, the chainring works very well. Dirt and mud are effectively removed when overflowing the chain.

We recommend using a derailleur with increased cage tension (SRAM type 2-3, Shimano Shadow +), which reliably holds the chain in place and prevents the chain from jumping off.

oval shape
Ovalization of the chainring enhances performance through powertrain variation and drag optimization. When pedaling with the legs, the natural strengths and weaknesses are reconciled. Thus, a better use of the stronger muscle groups is achieved and in the weaker muscles a balance in the working path (lower stroke) created.

VCLT (Variable ChainLine Technology)
Garbaruk works with chainrings with a changing chain line , which depends on the number of teeth. For other manufacturers, a fixed chain line common, but must be chosen so that even larger chainrings do not touch the chainstay. The smaller the Garbaruk chainring, the closer it is possible to place it on the chainstay. The chain line is thus even more optimal, since the chainring is aligned almost centered to the cassette.
