Frequently Asked Questions

What fits with Shimano 105 Di2 REAR DERAILLEUR 2X12s?

Shimano 105 Di2 REAR DERAILLEUR 2X12s is compatible with cassettes, cranksets, chains, shifters that match its technical standards. Most importantly, it requires matching 12-speed components.

Can I use a higher or lower speed chain with Shimano 105 Di2 REAR DERAILLEUR 2X12s?

No, Shimano 105 Di2 REAR DERAILLEUR 2X12s requires a 12-speed chain. Chains for different speeds have different external widths and internal profiles, which will cause poor shifting or mechanical interference.

Can I mix Shimano 105 Di2 REAR DERAILLEUR 2X12s with MTB components?

While some mechanical standards (like cassette spacing at certain speeds) may overlap, Shimano 105 Di2 REAR DERAILLEUR 2X12s is optimized for Road use. Mixing with MTB parts often fails due to differing pull ratios and chainlines.
