Handmade in Minnesota, USA by Wolf Tooth
Machined from 7075-T6 aluminium
ED coated steel bolts included
This is a spider for use with the Race Face Cinch system
3 different chainline options are available. The number and letter refer to the mm offset and direction from the mounting face to the centerline of the teeth:
M8 (minus 8mm - dished towards the frame) is for standard 49mm chainline. This is for use on bikes with 135mm QR, 142mm thru axle, and some 148mm bikes.
M5 (Boost - minus 5mm - dished towards the frame) is for 52mm chainline that boost bikes may need. This link explaining 148mm ""Boost"" spacing will help you decide if you need the M5 or M8.
P2 (plus 2mm - dished outwards away from the frame) is for fat bikes that have 190/197 rear spacing but use a 100mm spindle. This is now very common on production fat bikes to keep the q-factor slimmer
You will be able to access all bolts without removing the spider
Line up the little dot on the ring with the dot on the spider. Don't worry, you cannot install the ring in the wrong rotational orientation.
Be sure the bosses on the spider ""plug in"" to the chainring.
Torque bolts only to 4-5 Nm and use blue Loctite thread locker
