>>1086280>>1086367>>1085899>>1085805>>1085803So I got the fargo. Took the noobbies off and put on some schwalbe super moto-x 27.5x2.8 tires. rides well. mostly stock. Rival derailleur replaced with GX, wheels are stock so the whole thing is built around boost spacing. Right now it set up 34x11-42 and desu, it seems pretty slow. I dont have racks yet, so I can't ride it loaded down, but with just my fat ass on it I seem to spin out all the time. I really like the plushness of the + tires, I haven't had any back problems and I have been going mostly on gravel the can be pretty washboard and bumpy, I just wish I could go a little faster. I kind of lucked out in that my crank is fucked and sram is going to warranty it. Sram offered to give me a pretty steep discount on an upgrade, if I wanted to do that. I could get an x0 (x01) crankset for $60 more, or an x01 eagle for $80. My problem here is, with boost spacing my bike can only take a 36t chainring. With a double I can run 42t big ring, which seems perfect but IDK if I can still run + tires with a regular chain line. However, if I want to do that I would need to get a new set of alternator plates and a new rear wheel, minimum and that seems like a pain in the ass. If I get the eagle I will have a 10t meme cog and 36 chainring, which would be like a 38/11 traditional gearing, but I would have to get an xd driver, which is $100. That seems like it would be quicker, but not quite as appealing as the 42t on the double. However, with a 2x10 setup (42/28 rings, 11-36 cassette) my low gear ratio would be .7... whereas my low gear on the eagle would be .72, so it would climb better.
>tldrI got a basically free set of x0 cranks coming my way. I was thinking about upgrading my groupset anyway and now seems like a good time. Is there anyway to run a double with boost spacing? Could I just run a spacer on the bb? If not, would it be worth switching to eagle for the extra range?
