    Cheap way out, 700c on my 29er

    Don't have the extra cash to spend $1500 on a cx bike right now, but would it be ok for me to put a 700c wheel set on my 29er for when I ride around town.

    Or should I just save up?

    You should be able to put cross tires on your 29er wheels if you wanna go that route.

    Well I know it'll fit, just not sure if I would be going backwards in the processes?

    It will work just fine, but you will still want a cross bike. . . . .

    Oh for sure, will I be able to keep up better since the tires are slimmer, less rolling resistance.

    I run Club Roost Terras on Gravel. Don't know what the limit is, but I would not go much narrower than the rim width (i.e. on 23mm rims don't use 19mm wide tires). Sheldon Brown has an article on this (and everything else) with a ratio he recommended.
    The most expensive bike in the world is still cheaper than the cheapest open heart surgery.

    what's the width of your 29er tire?

    i've used a cx tire in a 17mm 29er rim.

    29" IS 700. Just get some new tires. I ride a 29" MTB to work everyday with 700x40mm tires.

    I've ridden and raced 700x33 CX tires on my American Classic 29er rims (1600g/21ID) for two season with no burps or issues. Works great!

    My next wheel set for cyclocross is hopefully going to be Roval Control SL wheels weighing in at 1370 grams and 22ID. I've made a deal with myself that I have to lose 10 pounds before buying though.

    I'm currently running 40mm WTB Nano's on a set of C29ssmax's. No real reason not to do it.

    What is your goal? You asked about being able to "keep up better" but I'm not clear who you're keeping up with.

    Replacing MTB tires with road tires will make the bike feel a lot zippier on pavement and over a long enough distance the time saved will probably be measurable. You'll pick up maybe 1-2 mph making this change and you'll experience a bit less fatigue. Replacing MTB tires with CX tires would provide less gain on pavement, but would still let you take the bike off road.

    Either way, a second set of wheels is probably a good idea because changing tires is enough extra hassle that you probably wouldn't end up doing it very often.

    ^ this.

    Most of the drawbacks of using a 29er for cross/road are not related to the tires...

    Aerodynamics and gearing are much bigger hindrances.

    Agree with a spare set of wheels to avoid having to mount tires constantly. Once you have the money you can use them to build up your cx.

    FWIW I went with these on my cx. Right now only running the rear with a 700x35 Happy Medium. Downside is the rear hub is actually an SLX and I need six bolt adapters for these hubs, but the price was hard to beat and the SLX has surprisingly excellent engagement. Mine came pre taped so all I needed was a valve and sealant to get them setup tubeless:

    I have been running some 40 mm tires on a crave 29er rigid for a few seasons,goes great they are mounted on sram roam 50 wheels i use a 32 t cassete to gain some top end.works ok but you will like a cross bike better if your area allows for higher speeds.

    I've run 35c tires on my 29er rims for commuting and gravel riding. Since it's only 10 miles each way I don't notice much difference aerodynamically. I do notice how much quicker the lighter/skinnier tires are though.
