For those who want all of our recent
Field Test reviews distilled down to just the pros and cons, here you go. Don't worry, though, we still have a very scientific speed test, the infamous Huck to Flat, and a roundtable discussion on the way.
Commencal Meta SXPros

Our MTB history is littered with head scratchers
645ish top tube for a large is simply too much for me. This isn't only too long in terms of MY body, which you alluded to, but also in terms of balance - compared to something steeper in the seat tube, it just doesn't have that planted feeling on the front. I also feel that even my Spire has too long of a reach at 485. The Enduro is larger still. The combination of longer reach and lower stack again gives the Enduro a very large feeling. While it does have balance, I would say dimensionally I would like it to just be a little shorter and taller. I think this does a lot to give a better position in terms of feets, hands and eyes, and coaxing me towards and alround better riding technique.
The Enduro is a very good bike, whereas when it came out it was a fantastic one relative to anything else. Like I said, I'm putting something together and I hope it will address this larger topic. It won't be so much where the Spire or Enduro are, but more about where geometry is going.
The transition spire is a bit shorter in reach (7mm), and a bit higher in stack (4mm). That said, if you were to alter the bar height on the Enduro to match the Spire, you'd shorten the effective reach a bit anyway.
This is one of the reasons I've never understood the obsession with super steep seat tube angles. Of course, it has to be such that I can get that saddle position where I need it to be to create the perfect pedal stroke, but any fussing beyond that is pointless, and a slightly slacker STA also provides more effective saddle-drop for a dropper post.
Imagine dialing in that fit on flat ground, then raising the front of the bike up 10 degrees, this trashes your fit for a long climb by increasing your saddle setback relative to the BB. Steeper STAs are trying to replicate these proven relationships but for the climbing part of mountain biking, where most of us spend the majority of our time.
Challenge: S sizing. S1 on an enduro represents an Extra Small t-shirt size while the S1 on the Ibis represents the Small. This is from conversations with both brands and looking at the Geo charts. The Reach on the enduro is 464 for the S3 and 487 for the S4 with an Effective TT of 619mm and 644mm respectively. The reach on the HD6 is 454 for the S2 and 480 for the S3 with an Effective TT of 610mm and 630mm respectively. Stack on the HD6 S2 is 625 and on the Enduro S3 it's 620. Comparing the sizes is difficult becuase the geo's are just different, That said, at 5'8" I'm confident I was on the right size enduro S3 and HD6 S2.
Results: The Enduro felt much more stretched out especially climbing. It was a great bike and super balanced with the slightly longer chainstay but the lower front end and longer reach did make the bike harder to manuever than the HD6 in both directions
My consensus between these two bike is that the Enduro was better for straight line speed. It was super composed and fast in the rough- that suspension was buttery smooth and the 29" wheel was fast. But the HD6 is an easier bike to ride. It pedals better and has better manueverability with the shorter reach, higher stack, and smaller rear wheel, so much so that on a lot of DH tracks I was able to set PR's over the Enduro once I got my suspension dialed. This bike rips in the corners and is great in the air. It accelerates up to speed really quickly too.
I wish the HD6 had a SWAT box, but I've gotten used to using pockets again.
I acknowledge that for someboy 1-1.5" taller than me, the Enduro may fit better. It's all about what fits you.
Also- I have felt Transition bikes to feel very cramped in the seated position. I like a slightly slacker STA.
and enduro bike when geometry was still a bit conservative and reach provided some stability with the increased wheel base but now that ht angles have gotten slack enough the extra reach isn’t necessary.
Not sure if that's 'accurate' or not, but that has been my experience. Went from a 455 reach on my old bike to a 485 on my new one and I feel really comfortable on both, despite the large jump in reach. I think the biggest reason why is that even though the reach jumped by 30mm, the TT only grew by 6mm, from 615 to 621. For my next bike reach is going back down to 460, but TT is growing another 6mm to 627. FYI I'm 5'9" usually in between sizes for most manufacturers, so I typically choose based off a combo of reach and TT lengths.
It's interesting being between sizes as I can get along with a pretty wide range of reaches and TT lengths but I'm still really figuring out what I like most for an all around trail/all mountain bike. Being at the top end of medium and bottom end of large ranges basically means that most bikes are usually designed for people 2 inches shorter and 2 inches taller than you and I.
I'm going to get my saddle in the exact same position relative to the bottom bracket for the same type of riding because there is an "optimal" pedaling position for a given type of riding. From there the bike fit comes down to reach and stack. Stack height can be effectively altered by playing with bar rise/stem spacers, which really just leaves reach.
Looking at the Transition Spire and Specialized Enduro that Henry was comparing, they are so similar that one could easily make them feel nearly identical in terms of pedaling position/feel on the bike, with the Enduro being between 5-7mm longer because of the reach figure. Hence, I've never been convinced how effective TT is useful to me, given that I need to know STA, reach and stack height to calculate it anyhow.
"Low stack height combined with long reach" - same thing, don't you just need to raise the bars and that will increase the effective stack and reduce the reach
I personally have a hard time getting comfy on an XL (~500mm reach) with 650mm stack despite running 50mm rise bars, +10mm stem and 30-40mm spacers. YMMV. It does matter to some people and at the end of the day it's just easier for me to buy a bike with a tall stack than try to rig ways around a low one.
Unno - 644.5
Commencal - 642.8
Nicolai - 640-646 (depending on rear wheel size)
Trek - 632.1
Nukeproof - 631.25
Ibis - 630
Pole - 625
Chromag - 625
Did PB complain about the Pole and Chromag being too low? If you can fix your "low" stack with a single 10mm spacer, is it really an issue? I get that the crowd of very tall people might want as much as possible, but for most people it's a non-issue in this case and I can only guess that PB is bringing it up just so they have something bad to say.
Putting more spacers under the stem is almost never possible, because bike companies cut off the steerer tubes way too short (I buy new forks every time I buy a bike because of that)! So at least for me and my body, a low stack height is a no-go with any bike/brand.
The Onni is too stiff with a lot of trail feed back. Too race(e). No other problems You guys don't like it.
The trek super stiff but you like it. Has been refined for years and still looses chains but it's ok.
The criteria seems skewed to me.
Can you describe this feeling a bit as I think this is where it's unclear to me. Are you feeling lateral flex in the BB itself in the high-load berms? Like, you're able to notice a bit of frame flexing around your legs/feet in these high-load scenarios or are you saying the tire is sliding/washing out because of this?
The issue in a way is that the tires aren't washing relative to how much your feet are moving, hence my comments on grip. Hope that helps.
The Unno Burn in the smallest size has a reach of 435 and 445CS, which would definitely be a unique experience.
And that bike got rave reviews for handling in every test it ever entered.
Taking a bike out for a spin is much different from committing to a purchase.
Cons: Future of brand questionable.
I'd love an HD6, but I think the Commencal is more my pay grade.
Also, the way the chain drop issue was discussed in the podcast, it certainly doesn't come across as "fixed", but rather something that can be lived with in exchange for the positive aspects of the bike.
