I've watched SOOO many videos about this subject and this has BY FAR been the most informative.

I appreciate the terms and analogies you are using. Very much educational.

Wow. Who are you? You're the most knowledgeable, smart, well presenting, and explaining cycling guy on KZfaq. I was looking for this topic and, this video is by far the most informative! Subscribed!

STILL "thee" most underrated cycling channel on KZfaq.

Understanding Biomechanics and applying it on my cycling is a game changer. I have been riding and racing time trial and having a proper posture when riding my bike is night and day difference. I feel like it's easier to transfer power and it's easy to flash lactic acid because power transfer is pretty balance not just coming from the quads but anyways biomechanics is a real deal. looking forward for more videos sir and keep it up.

Great explanation. Thanks

Quite informative! Well done!

Just awesome man ! Your the man get stuff out.

thank you for the information 👌

Cool, i learned a lot👍 Thanks for the info☝

Jaaack! Hi my friend, just messing you to remind you own us that B. M. C. review and at least I am waiting for it very very excited. Cheers mi friend have a nice one

I loved it

Great video

Looking forward to team machine review. Almost bought one!

Very nice 🙂

so what is the correct stem length ?

Great video. I just hit subscribe. Any info on that gorgeous white bike? Make, model, wheels, etc? So beautiful, it is.

Great video Jack . Nice production again . Thanks for the answer to my question. I still wish I can put a longer stem at high speeds I feel my front end shaking. It makes me terrible descender. I would like to try a 100mm stem on an other bike to see the difference. Don't really feel like changing bikes now just for sn extra 25mm stem when I'm not sure if it will even make that much a difference. Thanks

I love seeing you on the SystemSix. You need to just go ahead and buy that thing. hahaha What size frame are you? I see tons of em for sale at discount prices. Now that the new Canyon Aeroad seeks to steal some of the Sys6 Thunder, you might even get one for a song.

Hi, I am a beginner looking for advice to purchase my first road bike. Background: My height is 148 cm and my inseam length is 67.8 cm. I have done my research and have set a limited budget to pick up a second-hand bike due to my cycling skills still requiring a lot of practice and improvement. Concern: My ideal bike is an XXXS in Merida (for point of reference). However, that is insanely impossible to find in UAE (part of Middle East). I have however found an XS road bike (Merida Scultura 300) which is still slightly bigger. My main concern is the reach (ideal: around 366MM and current at 373MM) and the size of the handlebars (and the drop curvature is too wide which doesn't let me grip the shifters very well). The current stem length is 100MM and the width of the handlebar is 400MM. Can someone please advise how short can I go on the stem length without affecting the bike handling too much or not at all? Would putting in a 70MM stem affect it too much? Looking forward to some advice. It shouldn't have to be so hard for a short person to upgrade and enjoy cycling 🙁 Thanks in advance!

The white bike looks like at least one size too big for the guy in the red jersey. His arms are stretched out too much, so it must be uncomfortable on longer rides.

is my 100mm stem just right for my 49cm frame? thanks

I suddenly need a captain america stem cap

what size of stembar can use may frame toptube 50cm? Thanks

I never break a sweat , i only use my gears and legs to cycle. I do 40 miles and i am 60. so i learned nothing from this useless video
