"Easy, compliant assembly. To be seen over time for the quality of the bearings."
"Perfectly suited to the renovation of my bike, lightweight and inexpensive, easy assembly with the TL FC32 tool provided that the small TL FC25 adapter is added. To tighten to 40 Nm, use a torque wrench and the Lezine Socket driver and TL FC25 adapter".
