Confirm before ordering
The RD1 MK2 fits by two things: the fin and the cage. The fin is a small interface that sets the cable pull for your shifter. A variety of fins lets one derailleur work with Shimano, SRAM, Campagnolo, or Ingrid shifters, and you select the version configured for your groupset. Changing to a different fin or cage is work for a professional bike mechanic. The cage sets the largest cog it can reach: the short cage handles a cassette up to 46 teeth, and the long cage handles up to 52 teeth. Hammer & Howl stocks the long cage with these fins:
- The R11SH fin for Shimano 11-speed
- The M12SR fin for SRAM 12-speed
It covers the widest range on one derailleur, from a 44-tooth cassette up to a 52-tooth, and that flexibility is worth a small trade on the smaller cassettes. On a cassette like an 11-44T the long cage is fully functional, but it is slightly over-caged: it carries a little more chain, so you may notice a bit more chain slap, marginally less crisp shifting, and slightly less ground clearance. A short cage is the tighter, more cage-optimal match for a cassette up to 46 teeth, and we can order one in. For a 10-44T or 10-46T cassette, the short cage is the optimal match, but long cage will also work. For a 10-48T or 10-52T cassette, the long cage is the only match.
