Custom precious hard coating (MOD. PREGIO)
Dimensions:
93 mm x 93 mm x 13 mm
Weight: 150 g

+3mm chainring offset (chainline 52mm/55mm)
Chainline is the distance between the centerline of your

Compatibility:
OCHAIN∙R is a 1X 104 BCD Boost active spider
It replaces the stock chainring spider or direct mount chainring so that you
match it with most popular cranks’ brand direct mount standards. Updated model
list on our website for directing the correct purchase.
Nethertheless, Ochain srl cannot guarantee compatibility with every single
frame mounting these motors and with every single cranks on the
market.
Bolt Circle Diameter or BCD is the
imaginary cirlce that passes through the center of all the chainring mounting
holes.
OCHAIN∙R 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∙R, 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∙R using 4 standard chainring nuts.
WARNING: OCHAIN∙R 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∙R chainring
bolts and nuts (tightened to 8 Nm).
Align OCHAIN∙R with your crank arm as shown in the picture.
Lasered mark signs “>>>” on OCHAIN surface show the correct crank arm
position. 
Finally re-assemble your crankset referring
to the manufacturer’s manual or to a professional bicycle mechanic.
OCHAIN∙R active spider different setups
Pedal kickback is measured in degrees to indicate how much the pedals rotate
backwards at a given point in the suspension travel. OCHAIN∙R allows the
chainring to rotate backwards in order to disengage the transmission from the
suspension, improving the whole riding experience and the bike’s performances.
Our engineers defined four setup possibilities, resulting in different degrees
of proportional rotation. The defined options are: 4° / 6° / 9°/ 12°.
OCHAIN∙R makes it easy to switch from one setup to another in seconds, using a
2,5 hex key.
An hex key is all you need to disengage the system by rotating backwords the
black regulation nut. Same key, now on the central allen seat, and you access
all possible setups. Lasered lines are there as a reference for you. Lock back
the system and you are ready to ride.
OCHAIN∙R is facing you, mounted on your bike.
Gently clean it dust and mud with a cloth.
NOTE: Please do not use any chemical products to preserve our environment.
The Black Regulation Nut (BRN later in this manual) has two sockets for 2.5
hex key, lasered marks indicate them. Insert the 2.5 hex key in the available
socket on the radial face of the BRN, as shown below.
To allow setup modifications, release the regulation system by slowly
unscrewing counterclockwise, for as far as an half turn.
IMPORTANT:
Do not unscrew more then half turn to avoid damages to the system and the
accidental removal of the Seeger ring.Now the regulation system is released.
Remove the hex key and insert it in the socket of the regulation axis, on the
central axis of the BRN.
IMPORTANT:
Never operate on the regulation axis without releasing the system first.
Unscrewing till the end point, the system will stop on the 12° position. Slightly screw clockwise and the system reaches the 9°, the 6° and the last 4° position The lasered graphic shows the order and the reference distance between regulations.
Once the desired position is selected, remove the
hex key from the central axis and insert it back in the available radial
socket on the BRN.
Slightly screw clockwise to secure the regulation system in the position.
The ideal torque is 3Nm.
