Description

These are Avian Cadence cranksets that have spent time on display in our store, so they carry some very small marks that are hard to spot once installed. They are in a polished finish and are otherwise the same pro level race crankset.

The arms are hollow forged 6066 aluminium on a heat treated 24mm 16 spline 4130 chromoly spindle, with chromoly pedal bosses and a CNC machined 7005 alloy 104 BCD four bolt spider. Sizes run from 170mm to 180mm. The bottom bracket is sold separately and most chainrings will need long 7mm chainring bolts.

Features

Ex display, very small marks. These have been on display in our store, so they carry small marks you would have to look hard to see once fitted.
Hollow forged 6066 arms. Hollow forged aluminium arms keep the set at 845g in 170mm while staying stiff under load.
24mm chromoly spindle. A heat treated 16 spline 4130 chromoly spindle, so your effort goes through to the chainring.
104 BCD four bolt spider. The CNC machined 7005 alloy spider takes standard 104 BCD chainrings, with long 7mm bolts needed for most of them.
Five lengths, 170 to 180mm. Available in 170mm, 172.5mm, 175mm, 177.5mm and 180mm, so you can match your current crank length.
