    Good point, crazy how quickly that can add up. I'm more likely to just wait until I upgrade to a new ride.

      $748.99 shipped for a chain, cassette, shifter, derailleur, and XD driver for my Hope hub from JensonUSA for the X1 level.

      Not sure from the local shops. Those of ya'll with a hook up obviously for less. I'm not going there yet, but when time comes to replace enough stuff all at once, it's tempting. The XD driver body setup for King or Hadley stuff is stoopid spendy.

      Four bikes with 1x10 now, one playing with a 30 x 11-40 setup that has been working very well. For drastically less $$$. Can snag a longer cage rear mech and one of the larger aftermarket cogs for uner $200.

      I'm inclined towards sticking with that for now. Whenever a derailleur blows up, plan is to replace with a medium cage and bump to a 40t rear at the same time. Running out of top end isn't an issue for me around here, and the 36t low is fine as well other than the once in a while end of a long and painful ride. Kinda nice having that bail out option, or when getting to places that have more climbing than my local riding spots.

        Front derailleurs still work too.

        I'm on a bike that's a bitch to set them up on so I was particularly eager to throw money at the situation. I'm glad I did but if I hadn't had a short history of bending front derailleur cages I would have cared a lot less. IMO if you're going to go 1x, and you pedal on descents and ride a bike or certain climbs that lend themselves to low gearing, scram 11sp is the only way to go. If you ride a light bike, only ride short loops, are just in really strong shape, then maybe 1x10 will work for you. I wouldn't run it with the shitty dirt around here and my 30lb trail bike.

        With a 1x10 you're sacrificing one end of 'normal' mtb gear range. That kind of sucks.

        But then again, front derailleurs still work.

          i rode a niner jet w/ 1x11 last summer at MTB OR after riding an ibis mojo w/ a traditional front ring setup (specs escape me) -- back to back days
          overall memory of it was: i didn't miss any extra gearing on the up
          (two bikes were totally different on the down so no comparisons there)

            BUMP - Old thread I know, but now that I'm looking at building a new bike, I figured I'd bump this thread because Shimano XT 11 speed system has kind of changed the costs of the best way to go 1x.

            Basically, it seems like if if you are building from scratch, or your 10-speed drive train has seen a lot of miles, or you are still on 9-speed, might as well go straight to 1x11.

            Let's say you have existing 10-speed (with clutch derailler), and you want to convert to 1x10. You'd need to buy:
            • Front narrow/wide chainring for 64/104 BCD mount, round or oval, 26 to 36t options available: $40-55
            • You could use your existing cassette, but if you don't like the range on your 1 x 11-36, you are also adding a 40t or 42t cassette extender kit: $70-80
            • You can possibly use your existing derailler with adjustments if going 40t, but if going 42t you are likely going to have shifting issues so now you're also looking at modifying your rear derailler mounting point (goatlink) or cage (RADR): $20-55
            • Also bear in mind that your drivetrain might be due for a refresh anyways, so why not just start with a fresh chain and cassette? If your cassette is 11-34 you need an 11-36 to do this update. XT chain and cassette = $25+$55


            MINIMUM COST: $40 (Just changing front ring and re-using existing chain/cassette, but if you have steep terrain or you are not in killer shape this is not a good route)
            MAXIMUM COST: $270 (11-42 with full drivetrain refresh and new derailler cage)

            Last year when I did this conversion I got a new cassette, new chain, was able to leave my cage alone with OneUp 40t/16t cog kit, and I got a RaceFace NW 30t for 104BCD mount which was all together just north of $200.


            Okay now let's look at just replacing your existing 9-speed or 10-speed system with a Shimano XT 1x11 drivetrain. You'd need to buy:
            • Front N/W chainring, same as before: $40-55
            • XT Rear 11x Shifter: $40
            • XT Rear 11x Derailler: $60
            • XT 11-40t or 11-42t cassette (works on existing Shimano Freehub): $65-75
            • 11x Chain: $25-45


            MINIMUM COST: $230 (Race Face N/W Chainring, 11-40 cassette, heavy chain)
            MAXIMUM COST: $275 (Abs Black Oval Chainring, 11-42 cassette, light chain)
            UPSIDE: Smoother shifting with less monkeying about with the rear derailler settings than the above option, compatible with friends/loaners if also using 11x and same rear hub size.

            To me it just seems like a no brainer when I compare to what I did last year. Factory 11 speed components will shift much smoother than the hacked in 1x10 stuff. The XT stuff is so much less costly than the SRAM stuff, and I haven't ever really had an issue with XT stuff.

            Am I missing something here? And forget about Eagle - this post assumes that money is something of a concern, because if it's not then you wouldn't be reading this anyways.

                  If I have the following, what size front ring should I go with if I wanted to covert to a 1x and leave the rear cassette and derailer alone?

                  Front Cassette: SRAM S1000 36/22T

                  Rear Cassette: SHIMANO 10S 11-36T

                  To keep things simple, does anyone have a 10-42t (or 11-4?t) 10 speed rear cassette? And if I found one could I switch out my current rear cassette for it?

                    Going from 2X10 to 1x11

                    I've been running 1 x 10 with a 30 tooth up front and 11-36 in the rear but needed lower gearing since I continue to get older and fatter.

                    Just got XT 11speed derailleur, shifter, 11-42 cassette and chain for $197 off bc.com rather than dicking around with a ghetto 10 speed 11-42 conversion.

                      Don't forget going to 1x11 may require a new rear hub as well.

                          So you need to do a little more homework before you jump into anything.

                          People who go to 1x on a 11-36 are giving up lots of gearing and making very deliberate tradeoffs about gear ratios. It really depends what you are riding and how strong you are. How often are you in your 22/36 or 22/32 and could you live without them? If you need those then you have to get a 42t rear cog. Do you ever need your 36/13? You need to do some math with your current drivetrain to figure out the range of gear ratios you need. Personally speaking, 11-36 would never work for me because I would need a 26 up front for climbing, and 26/11 isn't really enough for slightly downhill riding back into town.

                          As far as cassettes go, depending on your derailler you might be able to make a 40t work without modifications but I'm skeptical that a 42t can work (shift cleanly) without derailler mods. Praxis is the only company I know who makes an 11-40 10-speed cassette, everything else is a modified cassette.

                            Bingo. That's why I specifically said that XT 11 speed is changing the economics of how you do a 1x conversion.

                            I have to re-iterate that my XTR rear derailler with 40t/16t OneUp cassette mods shifted cleanly after very careful adjustment of the limit screws and b-screw, but many people with Shimano experience shifting stickiness and issues and can never really get it right without modification. That's why going straight to 1XT 11 speed gets you a clean system without all that dicking around of a "ghetto conversion" that Skistack is talking about.

                            (edited: clarified Shimano vs. SRAM shifting issues)

                              For 10spd, Sram midcage stuff can accommodate 42 cogs without any issues. If you're already running a Sram clutch, probably cheapest to stick to 10spd. Just went from a Wolftooth 42t GC on a Shimano 11-36 to the new Sunrace MX3 11-42, my X9 does fine. Going from the ground up, that Shimano 11spd stuff is probably the way to go.

                                ^ Good call on SRAM vs. Shimano derailler accomodation. I edited one of my previous posts.

                                I think you're right, the formula is a bit different if you are already using SRAM vs Shimano.

                                I also wasn't aware of a lower-cost alternative to the Praxis cassette. I'm not sure if that Sunrace was available last year when I made the switch - but now I see that rather lenghthy thread on MTBR ... a quick scan of the most recent 2 pages shows lots of discussion about Shimano related shifting
