    Planning stages of 1x9 conversion help

    Still a noob a few months on the mtb. I am currently in the planning process of converting my 3x7 drive train to a1x9 mostly for simplicity reasons but also for a little weight savings. My first problem I'm running into is that my current hub is a 7speed cassette hub. If I want to change it to a 9speed will I have to purchase a whole wheel with free hub or can I just purchase a free hub and use it to replace my current cassette hub till I have the funds to get a better wheelset?

    Depends on if you have a freehub or a freewheel.. Take a look at it and go from there.

    How do I tell if it is free hub or freewheel? It is a 2014 specialized hardrock

    There is info about that on the link I provided at the top of the page.
    I am pretty sure it is a freehub if it is a 2014. I would also say your freehub will likely accept a 8/9/10 speed cassette as well since it's that new. There is probably a spacer behind the cassette.

    Says freewheel on the description. It's a pretty low end bike they cut every corner these days. 10 years ago the hardrock was pretty decent for the money I had an 06 and it was a great deal. I wouldn't be surprised if it's a freewheel at all.

    I would ditch the fork and go with a suntour raidon or epicon instead of dumping money into the drivetrain. You will lose more weight where it matters, it will ride a million times better, and then later down the road you can do a 1x10 setup and do it right.

    Not worth it.

    Why not just do 1x7?

    I had thought that the Big S decided to stop doing freewheels entirely. However, a 7-speed cassette is narrower than an 8-10-speed cassette, so you still may not have compatibility.

    Pull off your rear wheel and take a picture from the cassette side, so we can see the lock ring clearly.

    Well I didnt think I could use parts like x9 with a 7 speed? And also I wouldn't get quite the range as a 1x9

    The range you need depends on where you ride it. If you do a lot of technical climbing you might miss your small ring up front. Like I said though, I'd invest money in a fork if you want to lose weight and gain performance. I mean, you're losing gear range and spending money to lose weight. A new fork would probably benefit you a lot more than your current plans.

    I agree a fork would help more but I do have a good friend that is upgrading forks soon and said he would sell me his rockshox tora solo air for cheap so I have that covered very soon.

    Drivetrain "upgrades" are about the worst value going, IME. Particularly the high-dollar stuff. I don't know SRAM well, but I think Shimano's value peaks around Deore.

    What's your end goal here? How long have you had this bike? How many parts have you thrown at it so far?

    I've had it about 3 months. So far the only money I have put in to is replacing a cassette I broke and some captain control tires. I really want a 1x9 or 1x10 setup and replace the crappy components this bike came with.

    Can you give it back?

    The way you're headed, you're going to pay for a Stumpjumper HT Evo about twice, but have a frankenhardrock.

    Never been there myself, of course. :-p

    No I can't return it now. Would I be better just going 1x7? Also if I do go 1x7 what kind of rear derailleur can I use? Most of them I see are at least 9 speed

    check if bottom bracket and rear hub is compatible, but seems kinda expensive for performance value...

    Derailleurs are 7 8 or 9 speed, so either one advertised should be good. At least shimano. I don't know about sram. But why do you need 14 less gears?

    Well I don't NEED it but I guess I just have upgradeitis. I just want it to have better components and I never use the outermost or inner chain ring so makes since to get rid of them and shave a little weight off at the same time.

    Re: Planning stages of 1x9 conversion help

    It's July. If you're losing any riding time to screwing around with your bike, IMHO you're doing it wrong. I'm swearing I won't even change my handle bar until after my last race, probably about six weeks from now.

    If you're going to do upgradeitis, do it well. Ask yourself if the Hardrock frame is what you want, long-term. I still have mine - it's proven durable and didn't fight me as my riding position got a little longer and lower. Now it's next to my desk at work, waiting for my next lunch ride. But if you really want something else, start with the frame.

    Can you post a pic of your crank? It may not be possible to remove chain rings without damaging it.

    Winter is a good time for these projects. Stuff's on sale, shop staff aren't busy, and the weather sucks. A lot of things you try to do to this bike are going to snowball, so not risking riding days is better.

    I switched my big ring for a bash guard because my fs bike was hitting logs with the big ring so it made sense to take it off since it was trashed anyways. But saving like a pound isn't really worth it to me to lose my small ring too. Mainly because I use it though. I was looking at going with a 36t rear cassette on a 10 speed setup and then maybe a 30 or 28 up front so that I keep most of the gears I use, but it didn't seem like it was worth the money so instead I'm cutting apart a 9 speed cassette for the 34t 1st gear and am just gonna make my own cassette with the gears I want. If I were you I'd start pricing out 9 speed single shifters, rear wheels, cassettes and chains, along with a chain guide or a clutched derailleur, and see if it's worth all the money. Spending 300 bucks or so to drop some gears isn't worth it to me. People who do that already have the rest of the setup, so it'd cost beneficial to remove parts without replacing them with other parts. You have to first build your bike up to a setup that you can remove stuff from and that's really the problem.

    And another thing, add a chainring to your shopping cart and you're replacing everything required to do a 1x10 setup. And that's the route you should be going in my eyes.

    No I'm not losing any riding time. I really like the hardrock and I think I will stick with it. I enjoy riding but between archery shoots and kayaking I only ride about once a week so for now I see no point in getting another bike when I can just get the one I have to a lot better components and just keep on riding.

    I just did all this to my hardrock. If you have a 7 speed you probably have to change the rear hub because it will not take a 8,9 or 10. I got lucky because my rear wheel was replaced under warrenty with a wheel that would work with a 10 speed cassette. I went 1x10 with a raceface ride crankset and a narrow wide 32 tooth ring in the front and a slx der and cassette and deore shifter. Dont forget you have to replace your brake levers when you do this. All of that was 205. I had already used the suntour fork upgrade and got the raidon shock for around 200 with shipping. I have about 900 in it right now and will probably have 1100 in it when I finish it(brakes bars and seat). Base model stumpjumper is 2000 so I don't see the problem with upgrading within reason.

    Well considering I was about to put my 3rd chain and cassette on and I am on my second set of cranks and chainrings since march, the step up to raceface and slx must be an upgrade from suntour and sunrace. I have put 1400 miles on my bike in 4 months.

    Planning stages of 1x9 conversion help

    Stick to 1x7. If you don't have enough gear range change cassette to provide more range. LBS can help with this.

    Weight savings will be minimal. Better to replace fork. Best to save up for a bike upgrade next year. Ride your ride, enjoy it.

    OK here is a pic of the cassette, unless I'm wrong it looks like a free hub according to the link that was posted. So does this mean I can just put a larger cassette on or will I have to change hubs?

    It looks like a cassette to me too.

    I don't know if you can put an 8+ on there. Take it off. You need two special tools, but they're cheap and you should have them for regular maintenance anyway. There'll be a big spacer between your largest cog and the wider part of the freehub interface if it's compatible with a larger cassette. If you're not sure, take it to your shop.

    I'm going to make one last pitch for a do-over. At this pricepoint, you basically get a collection of parts and a free frame that they're hanging on. At the bottom end of high-end bikes, you get a nice frame and some heavily discounted parts so you can ride it. Still nicer parts than what's on a Hardrock, but at the top end, it's fancy everything.

    I don't think it really makes sense to throw parts at this bike to begin with, more so since it sounds like you don't want to ride it that much anyway. But since you want to have fancy parts, I'd suggest pricing the bike that comes with those parts to begin with. You may find it costs less to buy a nicely equipped complete bike than to buy everything to put a vanity drivetrain on this one.

    Read the spec sheets on Specialized.com. Until you get well over 2000 dollars the parts are still lower quality then my bike with upgrades. I would be doing the same upgrades on a rockhopper or a stumpjumper. The parts are still x5 , sunrace and tektro brakes and samox cranks with spring shocks. Some of them even use 1 1/8 steerers with adapters to make it look like they use tapered headsets. Unless you buy custom there is always going to be something to change.

    My bike is 3 x 10, but I recently rode a 1 x 9. It was nice not having to think about gear combinations. However, I was not doing technical climbing. I would have been very unhappy with the 1 x 9 on a tough clmb.

    look down between the cassette and the spokes and see if there is what looks like a large washer in between. If there is its a hub that you can put a 8,9 or 10 speed cassette on. If not you need a new wheel or hub.
