best video explaining offset so far!!

now i understand it! thank you so much! the other videos was so confuse

Still waiting on the stem length video.

The true measure of a craftsman is how he uses a string. Very practical, sir. Nice touch with the pedal strap.

Another genius method. Thank you.

You are a genius. This video actually makes sense! I have two bikes with two fork offsets and I’ve been playing around with either swapping the forks or changing the travel to affect flop and trail. Your video made so much sense.

Спасибо братан, я собираюсь покупать новую вилку и хотел бы сделать управление более резким, думал что чем меньше рейк тем резче управление, а оказывается наоборот. Спасибо еще раз!

Sorry for my poor English. The current Chisel frame is, as you know, more progressive than the previous one. The factory head angle is 68 degrees and the fork offset is 42mm. Many people modify these bikes by installing, among others, a Reba with a 51mm offset, which significantly reduces the trail but slightly increases the wheel base. The bike will probably be more controllable, but won't there be an effect of a steeper head tube on descents, won't this Reba ruin the gains of the new geometry? By transferring the effect of the change in offset and wheel base to the head angle - will it be a change of about 1 degree or rather a less noticeable value?

Stating how offset increases affect wheel flop is excellent. I was originally thinking more offset, increasing wheelbase, would add stability and increase straight tracking. I've got a 70deg HT angle, and a Fox 34 Stepcast and trying to switch to a carbon fork. The Enve fork can switch from 44 to 52mm offset, the Whisky fork is fixed 51mm offset. Plus, the Enve fork is 10mm shorter in length than the Whisky.

what effect would have offset of the fork to the head axis

Good Job! Especially by yourself! You’re working smart not harder.

So so glad I stumbled upon this video... I need more.. I have been wanting to increase fork travel but know that is going to change the geo on my bike and have been looking for ways to offset the change in fork length so it doesn't affect the climbing ability and to a lesser degree, the handling. I will probably have to watch this again to understand it even better but a video including stem length, and perhaps bar sweep and height and other variables included would be so helpful.

good job thanks :)

A vertical stem is actually best, with zero flop. Mike Burrows put together a bike that was fully adjustable to check this. Interestingly BMW have done the same. Of course then the handlebars are out of reach, so you need a remote linkage. Historically the reason why we have inclined stems is to get the bars close to the rider. A Penny farthing has a vertical stem.

The flop force is surely the whole weight resting on the wheel, not just the weight of the wheel above the axis?

Thank you!!!

that's why I really liked my 72* head tube angle on my XC MTB back in 2017.. 2018. that angle was just almost perfect. of course.. for cross country bikes. for enduro or trail it's usually 68.. 67 66* for head tube angle.

Good job !!!❤. You are the second one I’ve seen do a ‘DIY’ solar job with inexpensive used solar panels. You have inspired me to really start thinking about really doing it. Thank you!

Excellent explanation, but needs more detail on riding characteristics for different purpose bikes. Another issue l have with my big feet is foot wheel overlap on road race style bikes.

Jeep bling decoration 😂....Ha !

this video gives 3 kicks in the ass to those GMBN offset videos

In Australia they call them Kangaroo Jacks. Which I use as a reminder to keep my body well clear of the handle in case it jumps up and kicks me in the chest or face and to use my foot to kick the pin, in case it bites my fingers.

Insofast has container insulation and you can even do it on the outside. TheContainerGuy up in Canada makes brackets if you want to stud out the outside for insulation and siding...that way you lose no interior room, you can weld to the walls and you can make sparks and they just hit metal not flammable stuff.

Great Video

Was that new ( one trip) , or used ? it looks to be in great shape?

@3:00 ...it´s 16mm I'd assume, Sigmund being German...?

Do you plan on making more bike fit videos? The two you've made are the best explanations I've found on the topics you covered. Would love to hear more from you about how to choose stem and handlebars for proper bike fit.

Parabéns pelo trabalho. Estudando e acumulando informações para construí os meus quadros e seus vídeos irão ajudar bastante.

Will a 51 offset give the bike a longer wheelbase. I'm building a bike and I want a longer wheelbase

At higher speeds, it's the gyroscopic effect that takes over increasing stability. You say here it is the castor and I disagree. I do like how you are showing trail as square to the head bearing angle.

My grandfather was a farmer, and he had a bunch of those jacks around... seemed like several in every machine shed.

Good to know. I just found out that my container is about 2’ close to the property line and the county is telling me I can’t have it but I filed an appeal. I’m hoping they’ll approve it and all I’ll have to do is move it! 😡🤞

Amazing video that clarified many things for me. I do have some further questions though. 1. Why is too much trail combatted by adding an offset instead of reducing the headtube angle? 2.Will you make a video on the whipple model of the bicycle, or any model that attempts to mathematically determine the motion and stability of a bike using classical physics? Thanks for your time.

That was the Best explanation of Offset I've seen in quite some time Brother, and I really appreciate it. I did feel as though I was back in School on this one, again Great Information........🤝🏾🇺🇸💪🏾

the flop is a major characteristic in motorcycle handling at low speed, in rough terrain, the handlebar get stuck or almost impossible to move if you stall the engine.

Incredible video! I learned a ton and the production quality was great

Thanks for the very informative tutorial. I would add that I use longer offset to give me greater clearance for my size 14 feet.

Instead of 4231 can it be done in aluminum?

I am digging the ToT vibe for the workbench shots. :)

Any ideas for keeping the tube in phase when making multiple bends? Or changing the phase for bends in different directions?

Cool, you could 3d print inserts and mill a casing for strength 👍

This is a new Tony!

nice intro ! chaos is very entertaining. and yeah, that middle dice definitely bottomed out, not sure what's up with the tube not bending properly tho.

I think of you make the 2 outher pieces from alluminium and the middle one printed with though pla and than aneal it in the oven (search for cnckitchen) he made a great video about that. You'll be able to make it work👌

Keep at it.

Might try making the blocks a bit longer, just to distribute the pressure more. And yeah, not rely on the plastic to pivot.. use metal backing that pivots. Nicely done!

Have you considered nesting your 3D print inside a cut section(think “U”) of steel tubing? The pivot points could be on the outside of the steel for the lower dies.

you should probably change the print orientation, because the weakness is between the layers

Probably need to print at 100% infill and support the backs of those blocks with metal plate vs a single weak pivot. Thanks for posting something not quite successful, often can learn more that way.
