FAQs

No. You’ll need SRAM’s Flattop chain. Despite both SRAM Eagle and SRAM Flattop chains being 12 speed, Eagle* chains are wider and have standard 7.7 mm rollers instead of the Flattop* 7.9 mm rollers. Using the wrong chain feels like you’re pedalling a bag of rocks (trust us, we’ve tried it).

The Rear Exit Cable Stop replaces the cable pulley found on SRAM’s 1x mtb derailleurs. On higher-tier derailleurs, SRAM fits these with a bolt. However, on derailleurs up to and including GX* the pulley is fitted with a rivet. To remove the pulley, the rivet must first be drilled out with a 5 mm drill bit. We don’t recommend that you try this at home; it’s an irreversible operation that could result in permanent damage to your derailleur or you!

Yes. If you don’t have a chainring yet then you should really choose a 12 speed model, but Eagle* chains will generally run fine on 1×11 chainrings. The teeth on these chainrings are around 0.1 mm wider when they’re new. This is enough to reduce the mud clearance but not enough to prevent the chain engaging properly. Additionally, if your 11 speed chainring is already worn it’s highly likely that it already has a tooth width similar to a 12 speed model.

Yes. The listed maximum sprocket size for SRAM’s road 1x long cage derailleurs is 42t but this is quite conservative. We’ve tested the long cage derailleurs with the SRAM XPLR* 10-44t cassettes extensively and we’re happy to recommend this combination.

No. Our upgrade kits are designed for specific cassettes.

1X12 Wide upgrade kit: SRAM & Shimano cassettes do not have constant sprocket spacing and, in two regions of the cassette, the deviation between SRAM and Shimano MTB is large enough to cause clicking and ghost shifting. We’ve tried this combination and although some users may find it tolerable, we believe that you should keep that OEM feel when converting to wide range 1x.

2x12SH upgrade kit: Our Shimano 2×12 ratchet is specific for Shimano road cassettes and is not compatible with the Shimano MTB range. This is due to deviation in the cassette width and sprocket spacing.

No. The SRAM GX 2×11 derailleur uses X-Actuation cable pull ratio so would need to be converted to Exact* Actuation to work with SRAM’s road shifters. Our cable fin enables this conversion on SRAM’s 1x derailleurs but the GX 2×11 uses a different style of fin so ours can’t be fitted.

No. Shimano shifters are very difficult to disassemble and contain lots of irreversibly fixed components (permanently riveted together rather than screwed or bolted). We’d really love to make a Shimano kit but don’t see it being practically possible in the near future. We do offer the 2x12SH kit for upgrading your SRAM levers to use Shimano 2×12 road though!

Yes, but you’ll need to fit our Cable Fin. This is because Apex 12 speed derailleurs use X Actuation cable pull, but SRAM 11 speed road levers use Exact* Actuation; our cable fin changes the derailleur to Exact* Actuation. See our Cable Fin Kit guide for more information.

Yes, we ship internationally. However, we do not handle taxes for international orders so you may be liable for applicable taxes and duties when your order passes through customs.
