Acolyte Medium Cage SpringLock Rear Derailleur

The heart of the Acolyte derailleur is our innovative SpringLock system. By pairing a customized linear rate high tension spring and a dual stage activation mechanism, we’ve developed a system that can provide substantial chain security when you need it and can be turned off when you don’t. To engage the clutch, turn the engagement bolt clockwise until it clicks. There’s no way to overtighten the bolt. To disengage the clutch for wheel removal, flip the switch. It’s that simple.

Four years. We warrantee all products to be free from defect in material and workmanship for four years from the original date of purchase.

Our derailleurs work best within their suggested max cog range. 42-46t for Acolyte and Advent. 46-48t for ADVENT X. Moving to a smaller range will work, but it will also increase the distance between your guide pulley and the cogs of your cassette. This will result in slower, sluggish shifting, and our engineers will be disappointed in you.

If you exceed the max cog specification, you can stress the system, damage your derailleur, and negatively affect shifting.

You can, but we encourage you to keep within the specified max cog range. 42t-46t for Acolyte and Advent. 46t-48t for ADVENT X.

FAQ: How To Adjust Pulley Gap

This video shows you how to increase the gap between guide pulley and cassette so that the chain can smoothly travel into the larger cogs.

Verify that your b-tension screw is adjusted properly. The adjustment should allow for an 11-13mm gap for Acolyte/Advent and a 15-17mm gap for Advent X between the guide pulley and largest cog of the cassette. If that adjustment cannot be made, there is a good chance that your chain is too long.  Most derailleur cages are eccentric.  As the cage is pulled towards the chainring, the guide pulley is then moved out of the way of the larger cogs of the cassette. Too much slack in the chain will allow the guide pulley to rest on the largest cog.

Proper b-tension adjustment can make the shifts into the larger cogs easier. When set properly the distance between the Acolyte derailleur’s guide pulley and largest cog of the cassette should be 11-13mm. The b-tension screw is located above the limit screws near the derailleur hanger.

Standard Acolyte works well with most 24” wheels. Check to make sure the rear wheel has a standard HG freehub and not a freewheel.

FAQ: How To Adjust Clutch Tension

A quick explanation of how to adjust the clutch tension on a microSHIFT ADVENT or ADVENT X derailleur with a ratchet-and-pawl clutch.

Remove the clutch cover with a Phillips head screwdriver. Tighten the clutch bolt with a T15 torx at quarter turn increments. This will add pressure to the friction washers and strengthen the clutch. Clutch strength can be tested by hand throughout the process.
