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.

We’re doing our best to make microSHIFT products available everywhere, all the time. We do our best to fulfill all orders as fast as possible, but sometimes supply does not keep up with demand. If your local distributor doesn’t carry microSHIFT, ask them to.

No. Advent has its own cable pull – it’s much longer than R9 to accommodate a wide range cassette. They do not work well together.

No. There are two types of mounts: MTB and road specific. The mountain shifter has a larger diameter, in order to allow for more throw. As a result, the MTB mount is larger.

Most our products use standard Shimano-style brake and shifter cables. The exception is our DS- and DN- series twist shifter, which uses a Campagnolo-style cable.

No, we work exclusively with regional distributors to sell our products.

We work with regional distributors to make products available around the world. We’re working to improve our coverage, but if you can’t find a product locally, try an online retailer.

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.
