    About 6 months ago, I decided to convert it to 27.5+. I got Hope Pro 4 hubs (by the way, they do still make an RDS front hub) and WTB Scraper rims with WTB Ranger 3.0 tires. I'm loving this combo too.

    Just today I received my new SRAM GX1 kit and I'll be making it into 1x11 with 11-46 Sunrace cassette. Will post pics when it's all done.

    At this point, not much is original on the bike anymore (cranks, stem, seatpost and bars only), but it's still going strong and I have no urge to replace it.

    Is your chainline ok?

    I am using raceface double chainset with a absoluteblack oval as 111. With 11 speed xt 11-46. I think a better chainline could be achieved with a turbine 30mm and reversed dish boost direct mount absolute black.

    My chainline is perfect right now (SRAM X5 crank with single 30T ring mounted on the inside of the spider, and XT 11-36 10-speed cassette). Hopefully it's still fine after going to 1x11, 11-46 this weekend! I'll let you know.

    Also interested in seeing how the Sunrace 11-46 turns out with the GX. Mine's got a 1x10 42T wolftooth and 30NW chainring. Seems to be fine for how I'm riding the bike now, which is less aggressive single track as I've recent built a 29+ for that purpose. The Fatty's just too heavy for when I need playful.

    How much BB drop and wheelbase change did you get going to 27+? also which fork are you using?

    The BB height and wheelbase were virtually unchanged - I did measure at the time, and it was really within a margin of error. I am using the On-One carbon rigid fork.

    I just got done installing the new drivetrain. Every gear is working perfectly and shifting is silky smooth. I used to swear by Shimano cassettes only (even on SRAM drivetrains), but this Sunrace cassette is a quality piece - I'm impressed.

    I bought the shifter, derailleur, and cassette as a package deal off eBay (vendor: mybicycleparts). Great deal and free shipping. I'm stoked!

    Here's the latest pics of my Fatty. 27.5 wheelset (Hope Pro 4, WTB scraper, WTB ranger), SRAM GX drivetrain with Sunrace 11x46. Shimano XT brakes.

    That is sexy. Nice setup.

    Wheelbase is determined by frame/fork geometry not tire size. BB height will change with tire diameter wheelbase will not.
