With the small chainring with BCD 74mm, every climb is no longer a nightmare. Our latest spider is based on the double spider and has additional M8 threaded holes for the small chainring with a bolt circle of 74mm. This spider fits our ST and OR cranks. Made in EU from high-strength 7075T6 aluminum. The scope of delivery includes spacers and 17mm  Titanium chainring bolts for the small chainring.

Please note that this spider is fully compatible with the OR and ST cranks. When used with the GR crank, the space between the outer chainring and the right crank arm may be too tight for some front derailleurs. If you want to ride this combination, please let us know in advance.
