Quick Summary
The Fredertent 7/8 Speed Bike Rear Derailleur Direct Mount Long Cage Derailleur is a rear derailleur for compatible 7-speed and 8-speed cable-actuated drivetrains. It uses a direct mount interface and a long cage design, so the key buying check is whether your frame mount and shifting setup match the part.
The listed 38T total capacity, 85 mm pulley distance, and limit screw and barrel adjuster setup are the main technical points to compare before ordering.

What to Compare Before Buying
- Mount type: This model uses a direct mount interface. Check that your frame uses the same mounting style.
- Speed: It is intended for 7-speed and 8-speed cable-actuated drivetrains. Match it to your drivetrain speed.
- Total capacity: The stated capacity is 38T. Compare that figure with your gearing needs.
- Pulley distance: The listed distance is 85 mm center to center. Use that as part of your model comparison if you are replacing an existing derailleur.
- Adjustment setup: Confirm that you are comfortable working with limit screws and a barrel adjuster during setup.
Compatibility, Size and Fit
This derailleur is meant for a bicycle with a matching direct mount frame interface and a compatible 7-speed or 8-speed cable-actuated shifting system. The listed reference setups include 14-28T freewheel or 11-28T cassette with a 28T largest cog for confirmed 7-speed setups.
Check your current frame mount, cassette or freewheel, and shifter speed before choosing an offer. Direct mount and hanger-mount systems are different, so the mount style matters.
Before You Decide
Confirm the direct mount interface, 7-speed or 8-speed drivetrain match, and 38T capacity before buying. If you are replacing an existing derailleur, compare the mount style and 85 mm pulley distance with your current setup. Review the cassette or freewheel range as well if that is part of your drivetrain setup.
