E.13 Extended Range Cog

The Extended Range Cog brings lower gears to your 1x10 drivetrain. Currently, 10-speed cassettes only go up to 36T, which is plenty for 2x or 3x setups. However, with the increasing popularity of the 1x drivetrain the need for lower gears is what’s keeping most riders from converting over to the dark side. The Extended Range Cog replaces another cog on your cassette to provide a lower 40/42T cog to help on those steep climbs. Recommended for use with a medium to long cage derailleur, the Extended Range Cog also includes an replacement B limit screw which is much longer than the standard B limit screw, to allow your derailleur to handle a large 40/42T cog.

The 40T option is only meant to be used with Shimano 34T cassettes. This is due to the fact that SRAM does not make a 34T and the shifting will be compromised with a 36T as the timing will not be correct. A medium or longer cage derailleur is recommended, however you still may need to use the included extended B limit screw.

  • Cog Material: EXA+ Aluminum
  • Thickness: 5mm
  • Compatibility: 10 speed

      Comments about e.thirteen e.13 Extended Range Cog:

      I was able to get this working perfect in about 30 minutes. Once I got the med cage derailuer tuned, it now shifts smoothly in all gears 11-42.

      I did not need the long limit screw for my setup. I was happy with the way this performed and bought one for my other bike too. Both are now 1 x 10 with a 11/42 cog.

      NO-GO on my Norco Range

            Easy to install on my Mavic Crossmax Enduros. Seemed to tune fairly well on the stand, but on the trail when on the pedals, the chain jumps and skips. This cog would not keep the chain, no matter how the derailleur was tuned. I tweaked away for hours and even tried a different bb spacer arrangement to keep the chain more in line on this cog. Maybe it's my bike...maybe it's the cog. Either way, it's on the way back to Jenson.

              I bought an e13 for extended Range Cog 42T Sram. I use my e13 with Sram X9 Type 2, 10 Speed. Everything is new, derailleur, chain (PC-1071) and cassette. Chain jumps on the e13 42T, plus it deforms easily. I had to file down the teeth of Sprocket for it no longer jumps.

                Running this on a 1x10 setup (XT) on my trail rig.
                Great upgrade for minimal effort and low cost compared to say, full XX1.
                Easy to install with clear step-by-step instructions and extra longer B screw.

                there isn't much clearance behind the cog. on my sun ringle charger pro hubs it would barely allow the lockring to go back on and then bound the freehub to the hub because it wasn't flush on the freehub and rubbed on the hub body. if you have lots of clearance between the freehub and hub body without much shoulder on the freehub you should be good, otherwise go with the other brands.

                i install on a bH zenith 29er. the hubs are shimano anf the cassette is a slx 12-36 i think. i install the 42 tooth but wasn't able to install the smaller cog on the cassette when remove the 13 tooth. so i remove the 12 gear but the 13 tooth still slip it's not tight enough on the freewheel. Do i need to remove a space (where) or my freewheel isn't good quality enough ??? i try to solve my problem. on my other bike with a xt cassette and a sun ringle hub i install a one up 42t with no problem.
