The chain catcher, also known as the “chain spotter” is a part designed to prevent the chain from jumping off the front chainring. The chain can jump off the front chainring when shifting gears too quickly or when going over bumpy pavement.
Chain derailment is only an issue with bikes with a single chain guide on such as the CrossCurrent models. These bikes do not have enough room for both inside and outside chain guides. The chain catcher physically puts a barrier to prevent the chain from coming off the front chainring.
The CrossCurrent X comes with the chain catcher installed.
If the chain catcher is not adjusted correctly, it might rub against the chain and create noise or may not be able to keep the chain from coming off the front chainring.
To adjust the chain catcher:
- Put the bike in 1st gear.
- Use a 3 mm hex tool to loosen the chain catcher slightly
- Move the chain catcher so that the device just avoids touching the upper and sides of the chain.
- Use the 3mm hex tool to tighten and lock the chain catcher in place.
