Narrow-Wide chainrings have definitely helped reduce dropped chains but they are still not a 100% guarantee.
The OneUp chain guide is for riders who want additional security. Not only does this product eliminate dropped chains, it helps reduce chainring wear. The model you are viewing is for frames with threaded BB brackets. This product is also suitable for frames with ISCG 03 (ISCG old) mounts since they usually have threaded BBs. Please confirm before ordering.
