GARBARUK chainring Melon Direct Mount oval 1-way narrow-wide Cannondale Hollowgram crank | Ai compatible
Garbaruk is a company from Ukraine, which has its roots in motorsports.
Design and production of tuning parts for engines and chassis was part of the Garbaruk company. The experience and knowledge gained have allowed cycling enthusiasts to take part in the production of bicycle parts. All steps from design, production to surface refinement take place under one roof.
7075-T6 Aluminum from Germany is the raw material from which the chainrings from Garbaruk are CNC-milled. The chainrings have some features that differ from competitors.
In order to keep the chain securely in place even without chain guide, the teeth have a special profile of narrow and wide teeth alternately. To ensure this even under very rough and rough conditions, the teeth of the Garbaruk chainrings are manufactured approximately 40% longer than normal teeth. Furthermore, the teeth are shaped in such a way that even in muddy conditions the chainring works very well. Dirt and mud are effectively removed when overflowing the chain.
We recommend using a shifter with increased cage tension (SRAM Type 2-3, Shimano Shadow +), which keeps the chain in place and prevents jumping.
Direct Mount mounting
The chainring is mounted directly on the crank arm and replaces the possible previous spider.
The result is a tidy look that saves weight while providing excellent stiffness.
These chainrings, specially developed for Cannondale bikes with Ai frame geometry, have an optimized chain line which perfectly harmonizes with the rear of the wheels. (E.g., Cannondale F-SI, Scalpel SI, Beast of the East, Bad Habit)
VCLT (Variable ChainLine Technology)
Garbaruk works with all Direct Mount chainrings with a changing chain line which depends on the number of teeth. For other manufacturers, a fixed chain line customary, but it must be selected in such a way that even larger chainrings do not touch the chain strut.
The smaller the cooking bar chain, the closer it is to place it on the chain strut.
The chain line is thus even more optimal, since the chainring is almost centered with the cassette.
Melon - oval shape
The ovalisation of the chain chain increases the performance by varying the drive train and optimizing the resistance. When walking with the legs, the natural strengths and weaknesses are brought into harmony. In this way a better utilization of the stronger muscle groups is achieved and in the weaker muscles a compensation in the working path (lower stroke) is created.
