SRAM Etap Hydro 1x
Has anybody seen a setup using SRAM Etap hydraulic and some type of wolf tooth or other adaptation to run a 10-42 cassette 1x ?

I've got a buddy doing it though I'm pretty sure he's 11-36. SRAM xsync 42 or 44 up front.

Only 1 person knows of someone doing this? I would have thought this would be more popular with the surge in gravel bikes and 1x drivetrains.

If anything I would say eTap might push those with a gravel bike to stay with a double. It doesn't require any extra cables to be run and you can always use the road chainring or subcompact chainrings to get a wider gear range. That being said I love my 1x and not sure if it's cheaper to source individual eTap parts or if eTap levers come with brake lever only for the left side only? My guess is most kits are drivetrain upgrades, shifters, FD, and RD. |

I have etap on my gravel bike and it would definitely be a step down to reduce this great groupo to a 1x, so I'm not surprised it's not a very popular setup.

Since ya gotta have a LH shifter on there anyway, why not add a front der and inner CR? And not have to contend with YUGE gaps in cogset or not high enough or low enough, gearing?

Pretty sure 10-42 wouldn't work with the existing eTap RD and a standard Woolf Tooth product.
I'm not riding eTap, but did set up red wifli 2x10-42 for a very specific road ride (extended 24+% sections) and even with the wifli cage, RoadLink, and b-screw swap it was a close fit for the 42. eTap short cage RD would need to be retrofit with mid or long cage. Theoretically should work to allow use of eTap RD, but.... As previously noted, need both eTap levers. |

It works. Well. Sidenote: eTap rear mech, aside from the obvious gearing limitations, lacks a clutch. Makes it kind of "meh" for gravel 1x atmo. |

While no SRAM wireless 1x clutch derailleur exists, I will tolerate a single shifter cable. It helps that the Force1/CX1 rear mech works incredibly well. Is the XX1 derailleur functionally any different than a long cage Force 1 derailleur? |

My guess is there will eventually be an electronic option for 10-42. |

I think I'd go nuts using 1x on a gravel/road bike.
The cog jumps are already pretty annoying IMO once you get to a 12-30 or 12-32 cassette. Yes Compact chainrings are annoying but at least they let you keep your cog spacing a little tighter in the back. I get 1x for a MTB but IMO gravel bikes still need some tight spacing for going fast on easy pavement/dirt areas where you need to put a lot of power down for a long time and you have to deal with winds... all cases where having the cogs spread way out can seem annoying. |

^ This is where I came down on the subject. I lowered my gearing at the crankset and with a 14t difference in chainrings and retained the reasonable gear jumps of 11-28 or 11-32 cassettes.
