This bike brings to mind an inexperience-based question: What is the appeal of a linked-driven single pivot (LDSP)?  I have owned and ridden exactly one full-suspension bike, and it is a Horst link design.

I know that simplicity is a valuable thing in and of itself, but a linkage brings additional bearings and whatnot into play.  I know that other designs separate braking and suspension forces to various degrees in a way that a LDSP design cannot.  Given that LDSP bikes are still the preference for certain manufacturers in certain applications, though, I know that there must also be positive qualities that someview as outweighing the benefits of a Horst or what have you. 

Are LDSP bikes poppier?  More supple/sensitive?  Do they create cool leverage curves or something that gives a bike a nice ride feel  Can some suspension/braking cross-talk actually be beneficial in some instances?  Is the axle path particularly nice?  What's the pitch? 

Not casting aspersions over here.  Legitimate inquiry from a place of humility.  

We can continue to talk about this over here to not derail this forum 

https://www.vitalmtb.com/forums/hub/frame-design 

But in my opinion there are benefits to a linkage driven single pivot design over a Horst link, depending on what you are looking for. The biggest consistent difference between Horst designs and ldsp is the anti-rise, where Horst link bikes are generally low (80% and below) and ldsp bikes are high ( above 100%) and each of those have their own merits. I love ldsp bikes, they tend to be playful, predictable, and consistent in feel and geometry, I'm designing a high ldsp DH bike right now that I hope to build in the next few years. I'll talk more about it on the other forum if you're interested.

What a beautiful master suppression technique* trying to end the discussion there 😄

That's fair, but the GX axs build is 6900 for the allied and the current Tallboy is 7149 for almost the same build... Unless the 4 bar Tallboy comes with a price drop why on earth would I get it over the allied? Or over a Norco Fluid or transition smuggler? Just going the long way around to talk trash on the new tallboy

SC has to do or say something to justify the change from VPP to Horst. There is too much competition in that space to just drop the bike and call it a day. Talk about the specific changes in kinematics, how they've adjusted them from the last Gen, why they did, and how they expect it to make your ride experience better, otherwise the bike is going to be a flop.

You would chose a horst tallboy over those bikes for the same reason you would currently chose a vpp tallboy over those bikes.  Frame quality, ride feel and kinematics, frame stiffness/compliance tuning/feel, geo fit/dimensions, brand loyalty/identification, colors/industrial design, warranty support, LBS/retailer loyalty and support, etc.  

I have owned countless VPP santacruz bikes and I also own a horst link bullit.  I have owned many other brands horst link bikes: specialized, rocky mountain, transition, norco, orbea.  Unsurprisingly, my bullit rides like a santacruz and has a few characteristics that other horst link bikes have that are nice.  Based on my experience with the vala/bullit, I don't think it will be a hard sell to get people to try them and spoiler alert... I think people are going to enjoy santa cruz's take on the horst link platform.  It won't hurt that it will be lighter, have better seat post insertion, better shock access and compatibility and potentially allow them to go down the rabbit hole deeper on size specific dimensions.  

I have tried the other brands you mentioned just trying to not be another guy on a santa cruz... for various reasons, quality, support, ride feel and most importantly sizing and fit to my body type, I have ended up with an all SC lineup.  I think a horst link tallboy will be better then the current generation tallboy.  I do not think a dual link, vpp based design is a make/break for me in sub 150mm travel packages where pedaling efficiency is abundant with modern shock designs and kinematics knowledge.  Having lower anti-squat, less pedal kickback is a great starting point for a 140mm travel platform.  

Mfw I drink the SantaCruz kool aid.

FW says in their Q&A that 27.5 rear wheel is superior for gravity riding, wonder if they will contradict themselves.

Full 27 or mullet? Because 29/32 mullet is still mullet

I think it makes a lot of sense to consider front wheel size and rear wheel size independently. There's no relationship between them as far as I'm concerned. Choose rear wheel size based on how you want your rear wheel to affect your handling and clearances, and then do the same with the front. If they don't like a 29" rear wheel now, then they're not going to like one just because the front wheel is even bigger.

Rear wheel size has a big effect on wheel path, and Frameworks really worked towards maximising the rearward path of the axle while still constraining themselves to a standard drivetrain. The smaller the wheel, the more rearward your axle path is for a given amount of kickback, so I don't expect them to change that up.

Their philosophy (paraphrasing/butchering) is the smaller 27.5 rear wheel allows you achieve an equivalent gearing to a 29, but with a larger chainring, which helps with pedal kick. Also clearance to your butt.. These kinda go away with a 32/29 configuration.

They also like to minimize rear center growth/shrinkage near sag, which apparently a 27.5 helps

That's because the BB to rear axle height difference is lower (the rear axle is lower), which, as per @AgrAde impacrts the axle path. The more vertical (or rearward) it is, the less shrinkage there will be.

The bigger the rear wheel, the more beneficial going 'high pivot' with an idler pulley is. Going from a 26" wheel (or a 24 even) changes rear suspension kinematics a lot. If you just moved the complete rear end upwards from a 26" wheel to fit a 29" wheel, you'd need an idler.

Getting early 2000s "throw ideas at the wall" engineering from guys with MSME from the school of Uncle had a lot of cool tools growing up from the 32" community. It's kinda fun but it's going to end in some embarrassing reflection in a couple years.

Can someone just tell me if any new XXL downcountry/xc bikes are coming this spring? If not I should just buy a used Tallboy. Tongue

Have you put any thought into an s5 norco revolver?  I demo'd one from my lbs (s4 at my 6'2" size).  They do have proper reach for us tall boys (ironic) and they actually ride a bit bigger then the reach figures suggest.  It was honestly the most fun xc-race bike I've ridden in recent memory.  Appropriate stack figures, super quick on the gas, proper fit, and good fc/rc balance for an xc bike.

I'm not sure when it's going to be released, but Forbidden has something more xc/dc oriented in the pipeline. They're not exactly known for making "compact" bikes. Ha ha

We're definitely going to have to go with a band-based mullet nomenclature system:

"I was rocking a Journey for a few months and didn't really like how it cornered. I was Billy Ray Cyrus for a few years before that so I might try a full Foghat setup before me and mixed wheel sizes go our Separate Ways."

Depends on what XXL means - I am 6'3 and ride a Norco Revolver S5 with the seat slammed forward. But I would call myself an XL rather than an XXL. 

Maybe the new Spur?

@ebruner  and @cmaac : I've definitely looked into that Norco Revolver. It's definitely the biggest XC bike right now, but I'm 6'7" and it would be hard to make a plausible attempt at making it fit. Fingers crossed for an XXL something this spring.

Overall a nice looking rig, but I really think Haro needs to stop competing with Trek for the biggest downtube font.

Just get a Mondraker or Ibis if you want crazy reach. I'm 6'4" and ride a Large Commencal Meta SX with a 485 reach and don't have any issues..
