I actually saw a bicycle brand called nutcracker and it had that written on the top tube :D

Now I need a vid explaining all the different types of suspension linkage and how they behave (VPP, DW, DELTA, etc)

Best geometry explain ever!!

Absolute hero of an episode. We've all been waiting ever since that ask GMBN ep a few months ago

THANK YOU! Great episode. After a near 25-year hiatus, I started mountain biking again. (Didn’t realize how much I’d missed it. Loving it.) As you can imagine, A LOT has changed; including terms used, varying types of MTBs, components, and more. This episode has provided me with clarity needed.

How about a video about different suspension linkages. Does the shock placement have any real difference? For example Canyon Neuron 2019, AL vs CF. AL has bottom mounted shock, CF has top tube mounted.

Hi guys how about 26ers frame with 27.5 front fork and 27.5 wheel set?

I've been waiting for a comprehensive video like this for so long. Thank you gmbn tech! I love the quick bike anatomy explanation at the beginning. Perfect video to send to friends when they ask about what effects certain measurements have, half the time I never even know myself haha.

You have made it so much easier for me to understand the dynamics that go into my bike. Thank you for the great information!

I've been waiting for this video without knowing it! Really helpful to know the anticipated handling changes with changes in geometry.

Thanks for this video, great and simple explanation about different parts of geometry, there's not that many good vids like this out there so definitely something that was needed.

Knowledge is a weapon. GMBN..🙌

Probably one of if not the most helpful MTB vids I’ve seen. Keep up the great work guys!

Make a video about fitting the mountain bike for really tall riders. In some countries it's not easy to find frames bigger than 21", which is not enough for guys >2m tall. There's no video like that on YT, so it will be great to hear some tips how to make 21" bike feels comfortable. PS. Another great video. Great job guys 💪

Great video Doddy. Been biking for over 35 years and I can honestly say I learned a couple things. Well done sir

Great video that takes some of the myths and headaches out of all the number crunching you seem to have to be able to do before committing to a certain size bike. Perfectly explained, great stuff!!

You are a good teacher, I have learned more on bike than I have learnt my whole life, thanks you

This is outstanding, guys! Top quality video, thank you!

17:47 so actually when 29" started it was only 26 existing which usually had around 1.5inch=38mm fork offset. 29 usually had around 2inch=51mm fork offset. so then came 27.5 to split the difference in the middle and it usually had around 1.75inch=44mm fork offset.

This was so helpful, I wondered what all these terms were and how to apply it to riding, now I can. Good speaker too.

I’ve been riding for over 30 years and l’ve learnt so much. Thanks. Brill explanation

Brilliant video. One of the most helpful I've found for mountain bikes.

Bravo! I've long wondered about most of this, and wasn't even aware of some of it. Fascinating stuff. And as others have said, an explanation of differences in suspension design would be most welcome too. Thanks for pulling this together.

I don't know how you make me listen to such a boring subject so intently. You have helped me as a beginner rider with so many of your videos, you and your team. Thank you! I ride a 2015 Diamondback SYNC'R with a 4" bar rise built up an old proflex 96 with a 1x10 as well as a 4"bar rise and I even got the wife out there with me an a 2018 GT aggressor with new hydraulic breaks bar riser pedals upgraded rotors mig shift 1x7 which when I get the money will become a 1x10 and I learned almost all I needed through this channel!! Thanks guys and ride on!

Great video Doddy! Looking forward to the up coming info.

This is really helpful, thanks. I paused a lot and took notes. About to buy a new bike and the jargon blows my mind.

GMBN has risen to the top of online MTB publications - just exceptional! Thanks!!

Great video and information, Doddy! Of course, I’ll need to watch it a few times to let it sink in. 👌

Great info and great way to show measurements. Helps alot when looking at a new bike for sizing or ordering a bike online. Thanks

super informative and very clearly presented, big thumbs up!

They should provide a range of numbers for each key geometry spec, and describe how those ranges change between riding style (XC, Trail, etc) and frame size (S, M, L, ...).

Great video, looking forward to more video’s as I am always interested in experimenting with different geometry depending on the trails / tracks that I ride both here in the U.K. and Espana!

Finally a step by step explanation. Most appreciated

Great job! This is exactly the kind of video I'm looking for. Thanks a lot!

I knew all this, but it really made me think about how hard it is to end up with the perfect combination.

I feel like I'm going to school and doddy is my teacher 😃

I still prefer to measure the bike by going by the length of the top tube not by the reach. When I am sitting it is supposed to be comfortable and while I am standing I am supposed to be agile and move around.

@ Ride Alongside How do you pedal a bike? EET is very much relevant and should be the first measurement considered.

@philmean5603

@@smalerider1727 I agree as well. It was a bit of a disservice of him to say ETT isn't really important. I feel it's more important than reach. Especially with these steep seat tube angle bikes, if they don't make the reach absolutely huge by old standards, the bike is way too short. It's all preferences and how you ride, but I ride in the saddle probably 80% of the time. It's hard to argue I should size the bike for only 20% of my ride, but that's the going advice these days...

@rataflas

Probably reach is more important for enduro/DH riders where you car about descending and not really on the seat pedaling... I kind of agree about ETT or TT measurement thought... it is probably the first impression if the bike is small or large. Stack is a good one! I never knew I loved a large stack just makes you feel more like in a BMX to me. Shame you are pedal strike prone

@j4m35doc9

True, but you can adjust the seated length of the bike with Saddle adjustment, offset seapost and stem length but the standing reach (ie weight distribution between the wheels when standing) is set by the geometry.

Nice accurate info my dude!!!!! Yeap, and let me just say that trail angles can change how a bike feels almost more than a frame being a little too long or short. When I raced BMX I had an XL frame, but ran with a fork that had the axle at the bottom centre of the fork tubes, not in front. So I had better stability in the frame with quick steering! Got me a trophy at Bexhill back in the day! 😎

Clear simple vid doddy, great job. Clear graphics, well done to the doodler with white pen!

It's just diamond frame... there's one diamond. There are two triangles though.

OK - I think I figured it out by connecting the dots. You get 5 points on the side view of a "Double Diamond"frame - front and rear hubs, headtube junction, BB, and the seattube-toptube-seatstay junction. The 1st diamond is the one we see clearly in metal - seatstays > toptube >downtube > chainstays. The SECOND diamond in the "double-diamond" construction includes one line that doesn't exist in metal, but is critical to modern geometry. It goes like this: seattube > toptube > FORK LEGS > "missing link". So there's the forward-leaning obvious frame diamond, and a second rear-leaning diamond with a missing bottom line that connects the front hub and BB. What? Ok so - imagine a Penny Farthing. Huge front wheel, tiny back wheel, and no chain - the pedals are mounted directly to the front hub. You can't draw that second diamond because there's only 4 total points. Later than the penny farthing you got bikes with equal wheel sizes, but still pedals directly on the front hub - no double diamond. It was only when someone moved the pedals out with the chain drive that we got the 5th point to connect and the modern bicycle. That invisible bottom line in the 2nd diamond is what makes bikes work the way it does, with stable rear for smooth power application and power disconnected from leading-wheel steering = nimble, controllable turns.

Thanks for this, very informative, I have not measured myself up for a bike since the early 90's and things appear to have changed!

Excellent video, for sure. I can't wait to see the others.

Thank you - excellent explanation, so clear and easy to follow.

This is the greatest informational mountain biking video ever made.

Great work Doddy. Finally I have a bit of an idea what the geometry of a bike is. Thanks.

As a carpenter, that has never got to use that laser level Christmas gift - I finally have a use for it 😬

love this..Answered alot of question about modern geometry

Thanks, Doddy, that was the best intro to geometry I've seen. Bookmarked.

Thanks Doddy, this is fantastic to know and really well explained

this channel is so amazing, thx guys!!

Nice vid! Been waiting for this. An idea for a video could be the different stresses that each part takes and has to accommodate. Maybe another one about advances in or about experimental geometry.

Brilliant explanation of mtb geometry, the best I've seen. Thank you.

Great video, very informative, and explained a few things I didn't know, and confirmed a few I suspected. I'd like to know some example of "average" and greater / lesser extremes of these dimensions in your next videos: what constitutes a short or long length or tight / wide angle for example. Keep up the good work :)

Thanks for the useful info Doddy

Thank you! Easy to understand and good information.

Thanks for the informative video. I'm more of an urban rider than trails. But, this was very informative. Keep up the good work.

Very informative. Thanks!

Great video. I'm 60 and was riding a Norco Sasquatch back in the early 80s and touring and mountain biking since then. Do I say this to pontificate with my superior knowledge about bike geometry? Not at all! Until this video I have basically been a geometry illiterate and ibnorance has been bliss. I remember putting a suspension fork on a late 90s rigid Cannondale CAAD 600 back in the early 2000s and the LBS guy telling me it would change the bike geometry. I thought "WTF are you jabbering about?!?!" Even with upgrading bikes over the years I just thought this was mumbo jumbo and happily went flying over my handlebars thinking this was expected. Finally, started to clue in it all wasn't just propaganda a couple years ago when I bought a drop bar mountain/adventure bike (Salsa Fargo) that could alternate between fixed fork and suspension with specific specs. This video would have helped me in cobbling together the rudimentary understanding I now have of bike geometry. Any young whippersnappers out there that are poo-pooing this knowledge, listen to the man.

The video was very helpful, thank you.

Some manufacturers like Trek, sometimes list geometry at 30% sag for full-suspension bikes. That makes sense, because on hardtail head angle steepens when you start pedalling in normal position, and on full-suspension it actually slackens. So why doesn't every manufacturer provide that info?

Nice video and very informativ, I´m a XC rider, but is good to know that kind of information!!......I love your show, keep up like this and please include more videos and info about XC bikes and races!!!!.....(I`m a big fan of your show)

Outstanding Content, more Please!

Not that any of these measurements wouldn't make a difference to different riding disciplines, but how long ago did manufacture start advertising the engineers notes??? Seems like a mind boggling amount of different things to keep track of vs what your realistically thinking of when one would buy a new or used offroad motorcycle. In any case, I always appreciate a rather diligent effort to make info like this digestible. Top notch content!

Superb Video .. Thanks a ton ..

I came to your channel to search for orientation regarding a vintage bike called the Cannondale M800 Beast of the East. The Beast’s frame has a sloping top tube, a high bottom bracket and a very short seat tube. I guess that the next step is actually riding in one. I come from a Cannondale M400 which has a traditional top tube, with minor sloping. Later I purchased a used AMP Research B4 bike and upgraded the rear damper with Risse air and oil unit. But I never evolved to more expensive and modern bikes and long for this M800. Thanks for the clarification of the elements of the bike!

I am just now getting into mountain biking. Very informational.
