Complete driveside spider swap for ROTOR 30mm OEM or UBB cranks.(Spiderswap1)

Bought a used ROTOR crank? Doesn't fit?

Need to change BCD?

Now we can offer a spider exchange, so you can!

ROTOR cranks fitted to some manufacturers production bikes (OEM), are specific to BBRight frames or Cervelo, we offer a service which means you can switch the spiders and make the crank fit.

These cranks will not fit through most frames as the axle will be short. The OEM lockring and spider need to be removed and replaced with a normal production ROTOR spider.

If you need a compact (110 BCD) crank but own a 130 BCD, we can switch the spiders for you. We can also create you a 1 X drivetrain for road or MTB cranks.

This service offers a full clean, removal, de-burr and re-seating of the new spider. 

See pics below, if your spider has the round holes, it has a built in 11.5mm spacer and WILL NOT fit any other frame except BBRight.

This service does not include chainring bolts or spacers and does not include any other products. Please let us know if you need the old OEM spider as we will not return it. For all other products, add them into your basket before checkout.

From the drop down variant, please choose OPEN spider 110 BCD, MAS spider 110 BCD, MAS spider 130 BCD.

ROTOR do not manufacture an open style 130mm BCD spider, only the MAS (Aero or filled in style).


The cranks need to be posted back to Velotech with the following form. This contains the postal address. We need all your details (address/contact number/email).
