    I have tried a hartail 29” a hard tail 27.5 with a very aggressive frame, 27.5+ hard tail and 27.5+ full squish.

    For trails like walnut the 27.5 hartail was really fun. Any kind of street/trials manuals etc was much easier on that.

    For longer rides my body really aprecciates the full squish, I can ride longer and my back doesn’t take the pounding. Bigger drops are soo much nicer

    If I had to choose just one bike it would be to go back to a slack 27.5 plus hardtail. I think 2.8 tires are more than enough

    NN front and rear on my bike. Have held up better than any other Schwalbes i've had. Rocket Ron's are a POS for this area. Hans Dampfs get severely under cut on outer lugs. Racing Ralph works OK but lasts about two miles. Rock Razor also works OK lasts longer than Racing Ralph. So far the Nobby Nics have been good for me. I ride Deception most of the time and the loose rocks will eat your tires.

    Went out with the wife to Mary Searight Park... First time with her GT Helion 27.5 bike and she cleared features that gave her problems in the past riding her 26" bike... Big smile on her face. No doubt in my mind that the larger tire is a huge plus to mtbing, and I found out that the '16 GT Helion 29er used the same frame as the '15 GT Helion 27.5... So I'm going to give 29 front, 27.5 rear a try. No worried about the BB height as at 12.8" it's pretty low to begin with (lots of rock strikes)... And not worried about the head angle becoming too slack, as the bike comes with a 69.5 angle, and from what I've read going with a 29 on the front, 27.5 gives you around a 1.5°-2° head angle change (depending on tire used). And I'll bump the rear tire size, up from 2.2 to 2.35/2.4; so I'm thinking it will be closer to the 1.5° change, which means a head angle of around 68°.

    Other things like reach and handlebar height can be easily fine-tuned moving the saddle forward/changing seat angle, and removing some headtube spacers.

    IMO. Your money would be much more wisely spent lightening the front of the bike for your wife vs going down that path.

    Not sure what you mean, as I what I described is all about the front? DO you mean getting a carbon rim?

    ESI chunkys
    Carbon Bar
    High grip, high volume tire that keeps the weight down.
    Bolt on thru axle Carbon rim, and light wheel build
    and finally a lightweight fork.

    What fork is on her bike?


    Your wife will get more benefit out of the lighter cockpit and bike than the conversion to 79er. Odds are, you will just increase the weight for her to loft over objects. Sure she will get some benefit if her strategy is to just slam the front wheel into rocks and let the bike do the work, but other aspects of the experience will be worse and might totally offset the gain.

    No offense but i ride searight on my cross bike and really cant see anything out there that a 27.5 couldn't do just as well as a 29. Pretty basic stuff. Im all for getting someone as comfortable as possible on their bike, but here has to be better ways. Besides, youre gonna need a new fork to run a 29.

    Yes, some 2.6x27.5 F&R would be much better than the 29/27 wheel combo

    A slightly wider and lighter seat of wheels to go with above tires

    and yeah, which model/year is that bike? If it has a reba, thats a pretty good fork for basic XC riding.

    She's riding a '15 GT Helion, this one... https://www.vitalmtb.com/product/gui...ion-Comp,15140

    I'm sure you can ride most of the Searight trails on your cross bike, and if I had one I don't think I'd be too far behind you either. My wife didn't really struggle with any of the features we tried to ride, I'd just like to see, given how much easier her riding is with the 27.5, how she'd do with a 29" up front. Since she's been riding the Helion she's become more confident towards attempting to make features she would have simply gotten off and walked riding one of her other bikes. It's really quite amazing how just a few rides on the Helion has changed her approach. Granted, the online reviews of the Helion were pretty good, giving praise to the rideability ease of the bike (has to do with GT's AOS suspension system)... And there are a couple of online threads about this only improving with the addition of a 29" up front, or both front and rear. The bike is a bit on the heavier side though, so it's a balance between improving the rideability and keeping the weight down. Just changed out the BB for a much lighter external bearings one, and the cranks for a lighter set. Going tubeless will lighten things up too, and some upgraded rims. She's not hitting jumps, so a carbon bar will work. Stem is a short 80mm Specialized, and the drive I converted to a 1x9 (Absolute Oval 32, Shimano 11-36 cassette, XT derailleur, Alivio shifters — I think the 36T cog is a huge help too, over the 34T it had before). Not much more area to save weight... Maybe on bearings, the Helion has a lot of bearings. And I got a great deal on a rear RS Monarch like-new take off shock ($35 at a Frankenbike table... Got it just before the seller closed down) which is a little lighter that the X-Fusion it came with. It's 110mm travel.

    Regarding the front fork... It's a Suntour Raidon — sealed cartridge rebound on one side, air with spring on the other side — 110mm travel that I just converted to 120 (easy... move pin)... But, the other day when we were riding at Brushy Creek she told me that the fork wasn't feeling smooth. Thinking it needed to be serviced, and being easy to service, I took it apart and found to my horror that the previous owner had used some sort of cement-like product to, based on the only reason I could come up with, in some way stop a leak... Honestly though, being that it was used on the sealed cartridge side I don't understand the thought, much less what was used. Anyway, it seem this stuff was put around where the dust seal goes, but some leaked down into the bottom case (legs) and dried into a kind of hard cementy-type substance. Fortunately not rock hard, more like a clay. It didn't cause any gouging of the stanchion, but in gently scraping it off and lightly buffing with jeweller's compound, the gold coating came off. And again, fortunately, the internals of the Raidon are pretty simple, so after doing my best to clean out the bottom assembly, and cleaning up the stanchions, greasing where needed grease, I put it all back together... And added a little bit of 15W oil to each leg, as recommended by a few people (not Suntour though) online. Yesterday was the first time my wife gave it a thorough test since I did the work and she said it worked great. Which I was glad to hear.

    The above aside, I had intended to take advantage of the upgrade deal Suntour has, and after speaking with the Suntour rep, the fork I settled on is this one... https://www.srsuntour.com/collection...nt=27528893315, as it kind of gives her multiple options, and is something she can transfer to another bike if she wants to. It has great reviews. Honestly, I think it's more fork than she will ever need, but will give her lots to help her confidence.

    Regarding the 26/29 thought... The Helion has a 12.8" BB height and from her first ride my wife was telling me that although she loved how the bike rode, she was hitting her pedals far more often than when riding her other bikes. To help with this, I converted the fork travel from 110mm to 120mm, and put on a pair of 170mm cranks. She's 5'7", so the shorter cranks work fine for her leg length as well, and riding yesterday she only had one rock strike. Dropping from the 27.5" to a 26" on the rear would put the BB back low again. If anything, maybe instead of the 29" up front, I should just go with a larger 27.5"... More tire size vs. more rim size.

    Scroll down on this page to the white Suntour Raidon... Buying guide: 27.5 inch suspension forks you should look after in 2014

    Strange thing... GT says the fork is set at the 110mm setting... But Suntour says that the fork has only 80/100/120mm settings... And when I took the fork apart to make the 120mm adjustment, the three pin holes looked to be of equal distance with the space between the middle hole and the two on either side, which would suggest the 80/100/120mm settings. Could GT have been giving some marketing misinfo.
