2014 Carbon Hardtail for a 5ft 1in Female

[TigerMom]

Hi TigerMom.

I think I remember you saying you were having some trouble with switchbacks, is that right? If so a 27.5 would be a better choice over a 29er for the tighter turning radius and also your height. The Niner has a effective top tube length that is about 2.5 cm longer and a wheelbase that is 3 cm longer. The head tube angle on the two bikes is the same so the Niner will feel more stable at high speeds, but will be less responsive turning and the reach will be farther.

Are you bent on carbon? Are there any other models you've considered?

Hope that helps.

I am not nearly as good of a biker as you Wahine. So, I think that my problem with the switchbacks that I am currently doing has more to do with my lack of handling ability rather than the bike itself. In fact, after one month of practicing on my Santa Cruz Juliana 26er with all of Teamestrogen's great advice, I rode down the same switchbacks on a 29er without any problems. I think for my "beginner to intermediate" level of mountain biking ability, I can still use a 29er on the turns because I am not doing anything crazy gnarly. This is why I am still open to a 29er. Also, since I will be giving up my aluminum full suspension to go hardtail, I figure that the carbon with a bigger 29er wheel will feel similar when going over bumps....which is why I am picking Carbon hardtail over aluminum (I can't afford titanium, which is why I drool over your 2012 Moots Soft-tail). I tried an aluminum 27.5 hardtail and it felt terrible going over ditches and bumps compared to a 29er carbon hardtail. This is also the reason I am scared to buy a 27.5. But I have yet to demo a 27.5 carbon hardtail, so perhaps the comparison is not quite fair.

I would assume that the Niner carbon because it is a higher end bike was set up with a better wheel set and was probably tubeless which will make it feel different also.

Here is what I can tell you from first hand experience. Does my 27.5 roll over bumpy stuff as smoothly as my 29er. No. But it is darn close and SO much easier for me to climb on and is a nimble as my 26. Now my bike is also full carbon and a full suspension so that makes a difference in the cush of my ride, and the bikes fits much better than my
29er which I was stretched out on.

In a way I was lucky that I had the full range of experiences riding the 26er and the 29er. It made my leap of faith easier. I too would have been afraid if that had not been the case.
Either way it sounds like you will get a great bike. Keep us posted on the process. If you want any specific info, just yell.

Don't discount the opportunity to demo a bike in your size. While it's true that small and extra-small demos are less common, they're still sometimes available. My friend was able to demo a Niner Air 9 (not sure if it was alloy or carbon) in XS when the demo truck rolled through last summer. Never hurts to check.... I would also check with your local dealer. They may have your size available, or know of a customer who owns that size and would let you try it out.

Good luck!

TigerMom, this is a situation where a sizer cycle would be really helpful. A fitter could mock up the tow different bikes based on the gemetry given on the website and you could sit on both just to see how they feel fit-wise and then make your decision based on fit and projected performance.

This is exactly the kind of service I was hoping to provide with the purchase of a sizer cycle. But I'm not there yet. You could see if someone in your area has a sizer cycle and might be able to do this for you , if you can't find a demo.

I spent some time last night looking up geometry on various 650b bikes and I was surprised to find that all of the ones I looked at had a higher standover than the two that you listed.

Have you considered steel? It's slightly heavier (by that I mean about 1 lb for a good steel frame) but it would open up your option significantly.

I totally wish you lived in the area (@Wahine). But, I don't feel comfortable with internet viewing of my geometry, but I would totally have paid for a sizing with your personal attention.

I'm scared of steel due to the rust issue and slightly due to the weight issue (but more the rust issue). I am not the best caretaker of bikes. If it is raining/muddy outside, I usually still just hang up my bike without washing/drying. Hopefully, TE members won't yell at me for being lazy to my bikes. But I do take really good care of my dogs and my daughter

The sizer cycle fit is definitely an in person thing, it is not an internet fitting. I'm suggesting you might be able to find someone in your area that does it, in person, it's the only way to use a sizer cycle.

Steel carries some issues, but so does carbon. I used to ride a carbon mtn bike but I cracked a chainstay when I fell to the side into a rock. Fortunately I could replace it, but it cost nearly $300 to do so. With the number of times I hear rocks kick up and hit my downtube, I'd be afraid of fracturing carbon. Also, if you're not great about cleaning your bike, make sure any carbon frame you get is a single piece and not glued anywhere. Sweat, sports drinks etc, can break down the glue they use at carbon junctions and can cause them to fail.

aren't there some new carbon composites that are supposed to be more durable now?
