3DF ROAD CRANKSET 172.5mm R52/36

The 3DF cranks have the main technological features of their 3D+ bigbrothers, but at a lowerprice.  

It shares the 30 mm UBB spindle that ROTOR launched with its 3D+ cranks, which allows a weight reduction compared to cranks with a 24 mm spindle, making them compatible with all bottom brackets on the market (with the exception of the BB90 on Trek bikes). 

The 3DFs are produced by a combination of forging and CNC machining, and use ROTOR's patented Trinity Drilling System internal casting system, which gives the connecting crank unmatched torsional strength.
