RENNEN XL Chainring Nuts (x4)
Unable to load pickup availability
Description
Rennen Infinity chainring nuts make up the female half of the fastening system: fitted behind the chainring to receive the bolt, ensuring the assembly is securely tightened and centred on the crank spider. They are essential whenever the chainring is not threaded.
Like the bolts in the range, they are CNC-machined in the USA on multi-axis lathes from 7075-T6 aluminium, with the same attention given to stress distribution.
This is the XL length, measuring 9 mm compared to 6.2 mm for the Regular version. It is specifically designed for thick crank spiders such as the Answer Accelerator, where standard-length nuts do not provide enough thread engagement for secure tightening. Pack of 4 nuts for 4-bolt chainrings (104 mm BCD). Please note: the nut must be paired with a bolt of the same length — an XL nut with a Regular bolt will not tighten properly.
