Compatibility

Are ADVENT X 10-speed shifters and derailleurs compatible with Shimano 10-speed shifters and derailleurs?

No. ADVENT X uses a different cable pull from Shimano 10-speed systems. ADVENT X shifters and derailleurs are designed to work together as a group.

Can the ADVENT X system be used with any 10-speed cassette?

ADVENT X is compatible with standard 10-speed cassette spacing. We recommend a cassette with a largest cog in the 46–48T range. Smaller ranges may work, but shifting performance can be reduced.

Which brake calipers can be used with microSHIFT drop-bar brake/shift levers?

All microSHIFT brake levers are compatible with short-pull mechanical brake calipers. Hydraulic brake levers are not currently produced.

Can I use a smaller- or larger-range cassette with an Acolyte, Advent, ADVENT X, or SWORD derailleur?

microSHIFT derailleurs work best within their recommended largest-cog ranges. Acolyte and Advent are optimized for 42–46T and ADVENT X for 46–48T. Smaller ranges may function but can slow shifting because of increased guide-pulley distance. Do not exceed the specified largest cog, as doing so can place excessive stress on the system, damage the derailleur, and reduce shifting performance.

Can Acolyte be used on a children's bicycle?

Acolyte is designed to work with most 24-inch wheels. Make sure the rear wheel uses a standard Shimano HG freehub body rather than a threaded freewheel.

Can Advent work with R9 shifters or bar shifters?

No. Advent has its own cable pull, designed for its wider cassette range, and is not compatible with R9 shifters.

Are all thumb-shifter and bar-end-shifter mounting sizes the same?

No. There are two mounting standards: mountain and road. Mountain shifters use a larger-diameter mount because of their cable-pull requirements.

What type of cable should I use?

Most microSHIFT products use standard Shimano-style brake and shift cables. The main exception is the DS and DN series twist shifters, which use Campagnolo-style cables.

Technical Questions

How do I set the low-limit position on Acolyte / Advent / ADVENT X rear derailleurs?

How do I set the high-limit position?

How do I install a new cable in a flat-bar shifter?

You do not need to disassemble the shifter. First shift to the highest gear (smallest rear cog). Remove the cable cap if fitted, loosen the derailleur cable-fixing bolt, push the cable head toward the cable port, and remove the old cable. Feed the new cable through the port and out through the barrel adjuster, making sure the cable head is fully seated. See the microSHIFT technical documents for more detail.

Some shifters do not have a cable cap; on those models, the cable port is next to the upper shift lever.

How do I install a new cable in a drop-bar shifter?

How do I keep an Acolyte / Advent / ADVENT X derailleur from contacting the largest cassette cog?

Check the B-tension adjustment. The recommended guide-pulley gap is 11–13 mm for Acolyte / Advent and 15–17 mm for ADVENT X. If the gap cannot be achieved, the chain may be too long.

How do I increase clutch tension on an Advent / ADVENT X derailleur?

Remove the clutch cover with a Phillips screwdriver. Tighten the clutch bolt with a T15 Torx wrench in quarter-turn increments. This increases pressure on the friction washer and strengthens the clutch. Check the clutch feel by hand as you adjust it.
