NOTICE: In order to use 12mm springs with the V2 small bore AE shocks you will also need the AV1017 Spring Cups.
AVID B4.1 12mm Spring Collar Adapters are machined from billet 6061-T6 aluminum allow, black anodized, and 4-40 x 1/16" stainless steel set screws to give that premium look. These collars are used by sliding them over your stock AE collars and securing them in place with the included SS set screws. With these adapters you will be able to run the 12mm Avid Springs Sets (must also have AV1017 Spring Cups). Fits on any B4, B4.1, T4, T4.1, B44.1 and SC10.
