OCHAIN active spider installation
Disassemble your crankset from the frame, referring to the manufacturer’s manual
or to a professional bicycle mechanic.
Remove currently installed chainring configuration from the crank arm.
NOTE: If your bike already mounts a BCD 104 standard chainring bolted to the
spider and you want to use it on OCHAIN, remove the chainring from the spider.
For safety and performance reasons, make sure to check good conditions of
chainring with the help of a professional bicycle mechanic.
Install your chainring on OCHAIN using 4 standard chainring nuts.
WARNING: OCHAIN fits only with 5 mm female lenght chainring nuts!
Use Loctite medium on bolts.
Tighten all four chainring bolts to chainring nuts with the recommended nut
manfacturer’s tightening.
Use some grease on the external of the chainring bolts and tighten with a wrench
FULLY ENGAGED in the bolt.
NOTE: For a perfect result we recomend to use our OCHAIN titanium chainring bolts
and nuts (tightened to 10 Nm) and Carbon-T chainrings.
