This has quickly become one of my favorite channels. It's super refreshing to see someone taking a detailed and objective look at things rather than just riding the hype train and relying on clickbait/hyperbolous reviews. Would you consider taking a look at niner's rip 9 rdo? Thanks for the awesome content! Cheers :)
@TrailPOV I can respect that but I miss having someone that cut through all the marketing hype and personal opinions about bikes and just giving me the objective facts.
Thank you so much for this review. I have been waiting for it. I currently have a 2018 Meta AM, but my 2021 version is showing up in January. I Can't wait.
Thank God I found your channel! There are few places where you can find videos of the suspension kinematics! I would like to see something similar for COMMENCAL CLASH 2021-2022.
I love your videos, thanks for all of the effort that you put in! I would be really interested to hear what you have to say about either Pole or Fracebike’s designs, I’m sure you would really help put some of their ideas into a digestible perspective!
I wanted this review so much, great video as always. Also wanted to say that I support the comments that suggest looking at the new privateer models. Also, the new Vitus range would be interesting to see imo
I used to have the 2020 and I now ride the 2021. Let me tell you, the change is HUGE, and for the better. The new bike feels much faster and planted, and is much more comfortable for pedaling.
Congrats for this amazing content! A comparison between the different rear suspension regarding the number of pivots would be awesome! I'm referring to the differences at mobile or fixed linkage between the "chain stay" and "seat stay".
The geometry is completely different and way more agressive, the geometry does like 75% of the difference and from my experience feels way better, you shouldn't compare them only by kinematics numbers and also by feel and geometry.👍
Great video, really like the details covered here. With the new StumpJumper suspension ditching the Horst Link, one idea for a video would be to compare the suspension design/behaviors of the old vs. new StumpJumpers.
Thanks for the input. I ended up looking at this suspension design for a Patreon member. Very interesting which some distinct differences especially when it comes to wheel path.
I love your videos man. Very informative. Can you please do an analysis of the GT Fury 2014-2018 Suspension Design with the IDRIVE and how and why it won several DH world cups with the Athertons and even went into Redbull Rampage with Kyle Strait in 2014 despite being a linear single pivot.
Amazing Video!!! I was wondering if you have any sugesstions for good literature to write an scientific work about the physiks of the rear suspension of mountainbikes. Thanks
Very good and informative video - Thank you. Could You please do the Nukeproof Mega 2021, and how does it compare to the old 2020 frame model please - Thanks in advance. Liked, and subscribed, regards
Appreciate all the work that goes into your videos! Would love to see you cover Niner's CVA suspension like on the Rip 9 RDO or WFO. I ride a Rip 9 and I have to say that Niner's suspension is possibly the most advanced and unique in the industry. Would be great to get your analysis on it. Thanks!
@@flexmtb Unfortunately the video's take 40+ hours to animate so decided it's better to do PDFs so you all can get the data and I can put out more content consistently.
Please make a video about suspension like NS Soda / Transition Bottlerocket This is bikes for freeride, and I'm pretty interesting in this type of suspension!
Great video..I'd be interested to see you do a review on the new 2022 canyon spectral mullet and explain why they choose a coil shock vs the rest of the spectral line up has air shock.
Hello! You made a great video! I love it!! Can you do a video on KTM Prowler next time? I like this Austrian brand mountain bike so much, but I can't find its reviews on the Internet...
Oh... Thanks for your reply！！ I like KTM's mountain bikes very much, although they seem to be very obscure, few people are riding them... KTM prowler is my bike now, I wish someone could analyze this beautiful guy... I don't know whether the car is good or not
Do you know "KTM prowler"? It looks so handsome. May I ask you to do a video of it? This is "KTM Prowler.www.flidistribution.co.uk/2020-ktm-prowler-sonic-1
How would one calculate anti-rise and anti-squat values for a 6-bar suspension such as the DW6 system on Atherton Bikes? That particular system uses a layout similar to a Horst-link, but the lower bar is connected to the front triangle by two short, counter-rotating links instead of a fixed pivot. I'd assume one would treat it as a 4-bar system, with the lower link extending from the pivot near the axle to the instant center of the short links (so the lower bar would change throughout the travel), but I'm not sure if that's correct.
@@TrailPOV I think my assumption was correct, according to this article: pinkbike.com/news/pinkbike-poll-whats-your-favourite-suspension-system.html . I was unaware of this particular system until recently, but it seems very interesting. Atherton doesn't publish any kinematics as far as I'm aware, so maybe you could do a video on this in the future? The Orion system (also by Dave Weagle, of course) on the Esker bikes also seems interesting, but those are both fairly boutique and would be more for fun than for helping potential buyers.
@@theshortestcharles6886 Thanks for the link. I have actually looked at the Orion system for one of my Patreons and it definitely does have some advantages especially when it comes to wheelpath
Thanks. I try to get all my data from Cad drawings that I simulate linkage movements and then calculate the various params using a giant excel spreadsheet.
Very cool. Thank you! Can you take a dive into the 3VO Suspension system currently used by Jamis Bikes on the Portal 29" and Hardline 27.5" Thanks!! Keep up the great reviews!!
Hey there again! I’ve got libreCAD and am wondering how you figure out the leverage ratio and the shocks progressiveness, is there a formula...because I’m wanting to calculate the wheel rate of a bike so I can analyse it and understand its performance! Thanks 😊 great vid too, always interesting and informative!
Max I feel you man! TrailPOV if you aint gonna take on suggestions for bikes in the comments section, at least let the man know how to do it himself. You got real fans here, don’t let ‘em down
@@excusegenerator2098 If you plot the motion of all the pivots and the calculate the incremental movement of the wheel vs the shock through the travel you can easily calculate LR. As for progressiveness, that is based on the slope of the LR line.
Subscribed. Great visuals and explainations. I would love to see an analysis of the Banshee Rune v3. I just went from a Reign which you've assessed to this and I can't believe how different it feels (better). All manufacturers your their own benefits but I wonder if the numbers support this...or is it just placebo. Thanks!
Howdy Matt, what software do you use to create the graphics as well as the graphs? I’m hoping to break into the industry and have been studying suspension designs for a few years… been drawing and measuring on paper!! Thanks!
As much as possible I take the geometry data from 2D CAD diagrams of the bike. Alternatively I use a photo along with geometry data from shock length and chainstay length to account for the perspective effect cause by the camera that elongates the far corners of a bike photo
@@TrailPOV Where do you finde the 2D CAD diagrams of all those bikes? Im an engineering student and so far i was doing measurements of my bike by taking pictures from as far away as possible and then taking the crankarm or shock length as scale for counting pixels...
Hello, I have this bike and was thinking about puttig a coil shock, but at the end you said it wouldn't be ypur first choice. Wich one do you think is better?
I have some general question about this argoment, With smaller crown we have a lower anti squat exactly? and than, i can't understand the pratical meaning about "100% anti squat"....can you explain me please? thank's a lot for the video about the suspension design , i love riding my beast and know how it works better and better...🤘
100% anti-squat means that the chain force counteracts the weight of your body moving backward by slightly pulling the shock. In other words the suspension is elongated by X and at the same time your body compresses the suspension by X also = bike stays level
Can you take a look at the Norco Shore. I'm curious what the anti-rise values are and also how the idler effect the anti-squat with the high pivot design.
Could you do a video on pull shocks (fox dyad, equalizer 3)? It probably won't be the most popular topic for you, but it will be super geeky, which I think you do better than anyone. I own a Cannondale Trigger with the fox dyad rt2, and the rear suspension feels so different, but the performance is absolutely amazing.
@@TrailPOV Could you do a Kona Hei Hei next it's a single pivot down country bike that incorporates flex stays into the design I think that could be super interesting from an engineering perspective.
@@eastcoastcruisin4071 Flex stays are such a difficult thing to model. One can estimate this middle of a link as a pivot, but ultimately one would need some simulation software to show how a beam will actually bend along it's entire length
@@TrailPOV makes perfect sense, Kona assumes that it flexes 5mm cause of how the shock is setup the stroke would only give 5mm of travel but it is marketed as a 120mm front and rear trail bike.
