    1x9 to 1x10 is it worth it??

    About 10 months ago I built up a new Niner air9 with a 2x9 setup. Great setup and have been very happy with it. I decided a month ago to convert to a 1x9 to simplify things. Have been very happy, but has taken me a little bit to get used too. The current gear selection is very close to what I used to have but just little off that I do notice it. I know time will cure that as I figure I've been riding the same basic gear set for 10 years now. With the only exception of the prior being a 3x9 setup. So I was kicking around the idea of going to a 1x10 to give me one more granny gear. Currently I have a 1x9 with an 11-34 cassette. The 1x10 would be an 11-36. A lot of guys I ride with ride the 2x10 or 1x10 setup and love it. I'm just not sure the cost justifies the gains?? I figure it will cost me $250 to make the change and if I sell my current parts probably a $100 investment.

    1x10 is the cats pajamas. But for that price, I would wait till you wear you current parts out then upgrade.

    How about just throwing a smaller front ring on... going from 34-36 in the rear isnt going to make that big of a difference.. But going from 32 to 30 or 28 up front will make a big difference and cost way less..

    exactly, I'm running a 30T chainring up front, it gives me the extra "granny" I need for long steep climbs. Love my 1x10

    I did drop down to a 32t up front when I made the conversion. Maybe dropping to a 30T would be the best way at $20 or so.

    Shimano CS-HG61 29er Cassette 12-36

    Shimano makes a 9-speed 12-36 cassette, that's what I use.

    The difference between 32-34 and 32-36 is barely noticeable and not worth the weight penalty imho. (more like half a gear) You could also keep your current drive train and just get a 36 cog or a new cassette.
    For a long time I thought that 9 speed was always going to be the cheaper alternative, but this season it seems like 10 speed takes the cake for good deals (especially on the oe stuff).

    I compensates for the 10% extra circumference of the 29" wheel , but it's only in Deore, no spider, so it weighs quite a bit more then the XT 11-34

    I did some research last night and discovered the weight issue. I'm not looking to add any weight so that's not going to be an option.

    Would not be worth it to me - I only use about 4 or 5 rings, not sure if I have ever used the big ring in the back. Pretty flat around here, most rides I may only use 2 rings. My bike has a 10 spd rear, single on the front, but 9 would have been fine with me.
    Women and cats will do as they please, and men and dogs should relax and get used to the idea.

    I got an 10 speed SLX shifter and cassette with an XT med cage derailleur and chain from Jenson USA for under $200. You should be fine with your front chainring though you'll probably want a guide.

    30t chainrings for a 104bcd crankset are rare and usually involve modifying your tabs a bit.

    I run a 1x9 setup with a 38 ring on 180mm cranks and an 11-34 cassette and have never felt I lacked anything. Plus, I can't imagine a 1x10 shifting any better either.

    Going from a 32t to a 30t in front is the same as going from a 34 to 36 in back. There is no difference. But true, that cost would be much less. With a 30t or 28t, you will more than likely spin out on flats.
    I live in SE Michigan, and it's fairly flat. I run 32t(sometimes 34t) 11-36 1x10 and I sometimes spin out with the 32t. I run 1x10 only because my bike came with 10spd. I would have been happy with 32t 11-34 1x9.
    To me, 1x10 isn't about better shifting, it's about having that 36t cog. Road riding benefits 10spd more, as having a steady cadence is easier with 10 speeds. I recently converted my road bike from 2x10 to 1x9. 10 speed was better, but I have an MTB cockpit( XO gripshifters, SD7 levers, flat bar) and it's pretty cool.

    Anyway, stick with the 1x9. And as irishpitbull mentioned, upgrade when parts wear out.
    Good luck

    10 vs 9 is only worth it if Shadow Plus benifits you.

    For me, Shadow Plus was benificial enough to convert.

    My 9 sp was like silk, and so far ten speed is as good.

    I'm getting one of those new MRP 28T rings for Christmas. I currently have one of those Shimano 12-36 9 speed cassettes and I'm thinking about putting an 11T on in place of the 12. Should be the perfect range!
