GARBARUK direct mount chainring for 8-bolt mounting SRAM cranks is an extensive solution for Road/CX and Gravel bicycles. Until recently used to operate with the Quarq power meter only, we designed the chainring to be mounted directly. Garbaruk chainring for 107 BCD is still to be used either with powermeter or spider.
We recommend using a rear derailleur with cage tension, which holds the chain reliably in place and prevents the chain from jumping off.
GARBARUK CHAINRING FEATURES
Special tooth shape guarantees a tighter contact with chain and softer pedaling (in comparison with regular chainrings)
Chamfered edges and wide mud gap keeps the ring from getting muddy
Increased tooth height improves chain retention while the bike is shivering and jolting
Overall bicycle weight reduction in the range of 150-400 grams (with no front derailleur and chainguide)
Manufactured using highly durable aluminum alloy
Variable teeth thickness prevents chain dropping
