I was just looking at hora's bike the other day and thinking how sorted it looked. In fact, I almost posted something like "Mate, that looks like a really sorted bike that looks all proper and not a monstrous shambles of ill-judged random tinkering to failure like that wretched Planet-X roadbike you had yeah?".
But I thought that was maybe a bit patronising. Anyhoo.....

I dont want to adapt to it. It feels better with 26'er wheels
In all seriousness, I'm not doubting the authenticity of your lived experience and all, but I find it very difficult to believe that after a good few rides of "adapting" to it/not obsessing about it you would be able to detect any serious difference.
I went 26" -> 29er -> 650b over 3 years (all fairly slack, mid-travel hardtails)
The 29er feels genuinely different from either the 26" or the 650b. The difference between 26" and 650b is really not all that great.
🙂
Bigdummy thats a pic with 26'er wheels on
I often wonder if the difference that people are feeling between the wheel sizes isn't simply down to the wheels and tyres themselves rather than frames and geometry.
I use a bit more tension when spoking my big wheels to avoid that deadish feel that some wheels have. (Assume I'm using a decent rim.)
Any 29er tyre is going to weigh more than its 26" equivalent. I have never tried to calculate the difference in effort in getting it up to speed - not forgetting the 29er doesn't have to rotate so fast.
After riding fatbikes, all this is academic anyway. Any smaller/lighter wheel bike feels zingy. 🙂
BB's raised for a start- last night I had a tinker- dropped pressures right down. It felt alot better 😀
I've also had to drop the sag on the fork more than I ran on the 26'er.
Tempted to run the 26'er in the rear tonight but I know it'll make quite a slack seat angle just too slack - it'd be good for a Alps holiday though.
I had a 26" suss, 29 hardtail, now have a 650 suss and still the 29 hardtail
Find the longer wheelbase the hardest adjustment currently, constantly running wide in berms/corners definitely not sluggish though.
Pretty much every strava pb is toppling and the bike is 2 months old.
Think you can just over analyze things.
I had a tinker .... It felt alot better
Go on with ye! Get the settings right before deciding the wheels are the wrong size!
😀
I don't understand why you would want to run 26" wheels in a bike designed for 650b. It makes no sense.
I can't see it making it much slacker or lower anyway to be honest. By the time you have your sag dialled in the difference must be negated surely?
For what it worth I didn't get on with my 650b trance. It just didn't feel right to me whereas loads of people love them.
FWIW I never got on with the 26" oranges, not really the wheels being the problem though 😉
Did you lower the handlebar after putting the new wheels in?
If not, go and do it before you do any more whinging.
I've only ridden a couple of 650b's so not a world of experience, but in a blindfold test I wouldn't be able to tell the difference in the wheel size.
Some people seem more sensitive to small changes in their bike than others.
Did you lower the handlebar
Stem seems to be slammed in the picture of it with 26" wheels...
🙁
only option is a droopy/neg rise stem then....
though the travesty of a non remote dropper should really be fixed first
Flat bar (if that's a riser).
Bar height makes a massive difference IME.
I've got a 650b and bloody love it. There, I said it.
If you prefer it with the 26 inch wheels then ride it like that!
As you've found out though you've dropped the BB and may get pedal strikes but you'll learn to ride around that.
The wheel size shouldn't make any difference to angles and slackness, the static angles stay the same even if you put BMX wheels on it, you only get a slacker feeling by running more sag at the rear or by putting one of the bigger wheels on the front.
It sounds like you're enjoying the feeling of being sat 'in' a long low bike and have lost that by putting the 650b wheels on it.
I'm pretty sure Brant chipped in on a thread a few years ago when 650b was just coming through and somebody asked him about running 26 inch wheels in the 45650b, he didn't see a problem other than what you've already mentioned re. the BB being very low....I'm sure most designers of most AM/enduro type bikes have experimented with really low BBs for the 'railing the corners' feeling you describe and incredible stability but in practical terms to put a bike on the market like that knowing people are going to be smashing pedals and hitting stuff on technical climbs etc just isn't appropriate.
I disliked my 650b HT for similar reasons and have gone back to 26 inch wheels there but still run a 650b full-suss and like how that feels....I suspect you wouldn't have minded if you hadn't tried the smaller wheels first!
You could always run the bike with more sag at the rear and an angleset on the front to further push the forks out and get the bike sitting lower on the bigger wheels?....that's what I'd do, I wouldn't sell that frame as it's just too good looking!....easily the best looking full-suss out there right now and I know that shouldn't matter but in the case of the Commencal most reviews praise the ride too so you've got the complete package of looks and performance!

Back in 05 there was one of these on show at a bike demo in the lakes, Tracy Moseley was explaining that Fabian Barrel was experimenting with the floating brake jack arm, in some positions it could be used to jack the suspension and drop the bike low into corners.
What about keeping the 650b rear wheel in and fitting the old 26" front wheel for a best of both worlds experience?
Yes it rolls quicker down trails but Im losing that.... Zing?
I'm not overly impressed with 29 tbh. Wheels weigh a sodding ton (1800g) and what with that weight being further out, feels even heavier. Haven't noticed it being faster rolling either. Hard work riding fast on tight trails with all the acceleration. If I find some money down the back of the sofa I may experiment with b+ but that is unlikely to result in any additional zing.
Makes my old Patriot feel brilliant on the techie bits by comparison. I hope someone keeps making 26er bikes because I still really like that wheel size.
£20 for some offset bushes, lovely job.
Remote dropper sorted, no more mid-descent fumble crotch-grabbing 😀
Bar height makes a massive difference IME
Does anyone other than Niner make a proper, negative rise bar?
A mate of mine, searching for more reach on his Moulton, fitted an old style 24" riser bar upside down. It added reach because the sweep went the wrong way. It was shocking to ride.
I've given him some drops from my spares bin 😯

I had one of those (lower end version). Tried the brake in the lower setting a few times in the alps, it pushed the bike into its travel on dragging the back brake, phenomenal going into berms, terrifying when you forgot and tried to use the brake to actually slow down.
I'm just not getting it. Last night I was oversteering(?) on any turns so maybe I have to start leaning in turning before I usually do?
I'm going to fit a 26'er rear tonight and give it a spin round a local trail- partly out of curiosity 😀
Then after the weekend if I'm still in the same frame of mind I'll refit the 26'er wheelset and put on slightly larger diameter tyres as a sort of offering/compromise to the 'bike 🙂

Syntace do one
Surely a 26" wheel with big tyre is near enough the same as a 650b wheel with normal tyre ?
I think you are overthinking this hora. Just ride the bloody thing.
I'll buy your frame if you want rid of it...
A 26" wheel with a huge tyre is the same size as a 27.5" wheel with a tiny tyre. Make it big enough and you can call it 26+
Perhaps you are struggling with the slacker head angle compared to your previous bikes.
The internet says 25mm difference. Back to back though (Maxxis& Maxxis) the difference looks way bigger.
Renton the angles shouldnt change that much
Iridebikes commencal have great prices. Im sure you'd like one. It'd be a whole lot better than a shonky on one full sus too
Have a minority of people convinced themselves that they're so in tune with their bike that these things really impact on the weekend's 20 miles rides?
Scunny why start a topic 'will I die' around a 650b/26'er fork/wheel combo like you did?
Hysteria from someone with obviously little bike-feel? Pwned 😉

Glad I wasn't the only one!
I went from a 456-Evo 26er to a 45650b 27.5er and with both bikes on High Rollers the 650b wheels looked massive compared to the old bike.
The whole 'just sling big tyres on your 26er' for the 650b experience doesn't do the difference justice IMO.
I'm not sure then mate to be honest.
I can sympathize with you though. Sounds like you are having issues like I was with the trance.

Something odd with that picture.
Look at the difference in height between the rim at the bottom compared with the smaller height difference at the top of the tyre

If you cant feel that.... Wow
Nothing wrong with the image, just the 26" wheel is sitting in front of the 650b/27.5" and the picture is taken at an angle...so the 26" looks to be lower...
Well yes, it looks a bit different but the important bit is the difference in radius, not diameter...
584 - 559 / 2...
So 12.5mm, half am inch (assuming like for like tyres and fork, unlike the pic above)...
You,ll easily find more varied BB heights between stock bikes based on geometry or adding more/less fork travel... It's not that massive a drop really.
shame you cant put them nose into the wall side by side to get a comparison that way.
I didnt notice much difference if any going from 26 to 650b
It sounds like yet another one of those bikes where Hora knows better than the bike designer.
Have you considered a career change ?
Ah yes the 5spot that I felt was awkward. Turner coincidently made changes for the next year that funnily enough improved it?
