RECOMMENDATIONS

• We recommend the use of a clutch style rear derailleur for the best chain security.
• We recommend using a T25 L-Wrench or similar for removal and installation of the bolts. An L-wrench works best, since the crank spindle may contact a socket adapter and prevent it from engaging properly.
• Use the same 3 bolts to attach the Wolf Tooth ring or we carry replacement bolts
• For a longer lasting and more durable option, check out the CAMO System that offers stainless steel chainrings.
