- 29er sizing.
Try some more frames, on all the 29ers I’ve tried the top tube and bb was the same distance from the ground as the same sized 26er and I ride the same sized 29er frame as I did 26er frame (6ft, 34leg, 19inch frame)Posted 4 years ago
The bigger wheels don’t mean everything is higher up, it normally means a bigger bb-axle drop than a 26er..
My full suss 29er has a lower bb than my old full suss 26, and feels lower when I’m riding it..steve_b77Member
Medium Cove Handjob, medium Genesis iO, medium Nicolai Helius CC all with 585/590mm top tubes. The first two with 90mm stems and layback posts, the latter with a 65mm stem & a Reverb
Now ride a medium Anthem 29’er and a medium Kinesis FF29 with 595mm & 600mm top tube respectively. They fit me just fine with bags of stand over, I’m 5’11” with a 32.5″ inside leg.
Anthem has a 90mm inverted stem with a layback post, FF29 has a 70mm zero rise stem with an inline post.Posted 4 years ago
Now, I’m not going to be buying a 29er anytime soon. I’m quite happy with the bikes I have.
Working in a bike shop it’s handy to know what fits you personally so you can relate to others. So to that end I’ve been trying any likely looking 29er for size.
Any 29er that’s the right length for me is far too tall in the stand over. I have no clearance at all
Any 29er that’s got enough stand over room is way too short like a sit up and beg shopper.
I’m 5’8″. 30″ inside leg, so shorter than average but not a midget. A medium sized MTB normally fits me perfectly
So what’s the crack with the sizing on these things then?Posted 4 years agotakisawa2Subscriber
5’9″ / 31″ on medium SIR.9 here. Just feels so right. Fits better than any other 26″ or 29″ bike I’ve tried. Niner only make 29″ frames so they are the all knowing voice. Or something.Posted 4 years ago
In fact, they have an all seeing eye in the sizing department. Plus, they burglarise your house to measure you, while you sleep.
air 9 medium should fit you fine, quite low standover
As above, I had the AIR 9 in a meduim and it was fine.
I’m 5’10 with about 32″ leg and all my 29ers have been a meduim.
My Niner RIP 9 had quite a high standover for a medium. I had an 18″ Scandal 29er which was brilliant, plenty of standover. My current Whyte T129-s is ok for standover, probably about an inch or so before the lads meet the bar 😀
Im my experience of 29er sizing the Ht’s are pretty good. Some FS can be a little high.
I tried a Santa Cruz Tall Boy LT and the sizing on that was all wrong for me. The medium was too small and the large was just massive, stretched right over and no standover at all.Posted 4 years agoamplebrewMember
I’m the same overall height as you, but with a 31″ inside leg.
I ride a 17.5″ 29er with a 23″ effective top tube with a 90mm stem.
I also have a 17.5″ 26er with a 22.5″ effective top tube and a 100mm stem.
Both have inline posts and are a great fit.
I’m surprised you’re struggling on standover with a 30″ inside leg.Posted 4 years agowobbliscottMember
I’m 5’9 with 30″ inside leg so similar to you. I’ve got a medium 29er. If I stand over my bike the top tube is close to my crotch, so not a lot of clearance, but I really don’t see it as a problem, I never had much stand over height on 26ers I’ve had. I ‘m never really sure what the fuss is about stand over height and why having a lot of it is desirable or advantageous – or is it a fashion thing to enable you to wear your pants with your gusset hanging between your knees?Posted 4 years ago
Really shouldn’t be any difference Pete. What bikes are you trying have to tried the same manufacturer in 26?
Mostly Treks, because that’s what we sell, so I need to know about the sizing but I’ve also tried a Whyte and a Ragley with little change.
Like I said in the OP, I have no intention of buying one anyway, but I thought as least I’d be able to get one to fit me!

Oh, and a Scott as well.avdave2Member
I’ve a similar inside leg and looking at 29ers the issue I’d have is stack. There are options with enough stand over but I don’t want my bars higher than my seat. If I go for one it’ll be rigid. I’m currently running my rigid bike as a 69er with 440mm forks and that works well. I reckon a scandal with slack set and the same forks would make me a perfect rigid bike bPosted 4 years ago

I have to SELL THEM. I’m not buying one!
I’m not going to be buying a 29er anytime soon
So you were possibly going to buy one sometime soon but now you’re not buying one at all?
Would you like to read that post back you yourself until you understand how you’ve contradicted yourself? 🙂Posted 4 years ago
