How to Choose The Correct Bike Size

Thanks for the video. It really help me because I am in between sizes 54cm and 56cm. I am currently riding a 56cm bike. The bike rides well but, the reach is to low and long especially when my hands are on the hoods. I watched the video for smaller riders by Emma and moved the hoods higher on handle bars and rotated the bars and little more up and towards me this help alot. What your video help me to see is reach is not just to the handle bars, but to the hoods. Which is like an extension of the handle bars. what about the crank length? Would shorter cranks help a bike feel more comfortable? I am riding 170cm crankset now, but have a 152cm crankset from a nieghbor. Would that crankset be to short for a 5'8 person?

How fast did that guy talk? 🤦‍♂️

please help me guys. my height 163, can I ride Marin Muirwoods M size which is suitable height for M from 168 to 178. I found that bike on used online platform and I want it so much but still worry about the size. help me.

I'm 5’9 I think 54cm is better but I find a really good deal at Tarmac but is a 56 …should I buy it? It would make a big difference

I’m 5”11 would a medium size frame work for me ?

Sit height... when you sit on saddle land your hill with your riding shoes or your shoes on wear totl the pedal. And then straigth both your leg and make their level at the same levelings.. to avoide quite higher saddle that makes your pelvicular swinging when pedaling.. . Rotating or pedaling alternatively is not reqly a complete fundaments of measuring bike fit saddle height. So both hill is on same level while the other foot is on pedal.

Great video. Best one I've come across! Thanks for sharing!

Totally confused. Didn’t help a bit. Simplify.

Great 👍 information 👏

Great video, but I am still missing more info about all the seat adjustments.
Do you have a similar video more focused on this topics?

very informative for a beginner like me..welldone 😀🤜🏼🤛🏼

It's not bike it's bicycle

crazy TMI! I came ignorant asking a simple question and I leave still ignorant but now confused. Please keep it simple guys.

I appreciate your effort here guys but the explanations as to exactly what stack and reach are
is not clear and seem contradictory. At 4 minutes 37 seconds into the video Chris demonstrates what stack and reach are using his hand, but what he describes is nothing like what is shown in the diagram at 1 minute and 30 secs into the video. also at 2 minutes 47, do " Long and low" and " shorter but higher refer to stack or reach or both ? Without knowing these answers it's difficult to use this information to make decision on the best size of frame, especially if you are in-between sizes.

Its not so much a matter “what you want” but rather your ability and flexibility. You can wish “racier bike” all you want, but if you feel uncomfortable on it all it aero advantages are negated. Get a bike that fits your body not “your wants”

I was going to try and get into biking but there are just too many things to consider. it became so complicated that I just gave up.

what's the wheel size?

Thank you

I guess millions of new or intermediate cyclists all over the world appreciate GCN so much for so much valuable knowledge for free!!! They deserve their success. Thanks GCN

1 size smaller than what dealer recommends is ideal for me… dealers tend to go to bigger size and that’s wrong

It almost looks like they don’t exactly understand what stack and reach is, given the different wrong definitions during the video.

From watching people when I'm out riding, most seem to be on a bike that's too big. They correct it by not putting hands on the hoods or by having locked elbows. I'd say if you think you're between two, you're really the smaller size

I'm still so confused

Can't do any of this ordering online as this is the only place to get bikes now.

The others should take their video down. This one is the best 👍👍👍

Can you sen me a use endurance baike please

why are new bikes so ugly?

Can 11 years old ride a road bike

is there a size for a 4'4 kid

: )

Nice

Im 1,77m tal & i have size 54 for my bike is it too short for me or is it good size ?

Hi sir could you help me the exact size of road bike and my height is 5'3" or 160cm.
As of now in have the twiiter road bike 48cm size but the top tube size is 53cm is too long and it is aggressive very aero could please help me the exact size

I'm 5'7" (67 inches) but my inseam is 33.5 inches(50%)... I read that inseam on an average person was 45% of their height so I should be 6'2" extrapolating that out...!!! I sit between a 52/54 but for me the ETT is important and should be no more than 535mm. I got an ebay bargain Carrera TDF as a winter trainer in the 51cm size- but as these only come in 2 sizes the ETT is 565mm! More like a Large and this is the smaller of the sizes...I had to replace the 20mm layback post with a straight MTB one, and drop the stem length to 80mm (tried 70mm but was becoming very twitchy)- my ETT plus stem should be around 640mm...I'm struggling at the moment looking for a new "sportive" bike- I need the shorter ETT of a 50-52 but want the higher head tube of a larger bike for a more upright position (this again may require change of stem and/or seatpost).... I bought a KTM E-MTB from Merlin in a size S (17" Seat tube) which according to their charts I was bang in the middle of the range, and to my relief for a £3k mail order has been absolutely perfect.... I Think it's about working out which manufacturers seem to cater for your proportions.... Looking at the 54 Sensa Romagna 2021 at the moment, it seems to tick all the boxes size and spec wise...

what brand/model is that front light you have mounted?

I cant believe you have made it so complexed. It doesn't need to be ! All manufacturers make bike different yes but they are for different reasons and for different people . This is were people are getting it wrong. I don't know many people who set there bike up them self's and get it right. me included and i have been doing this for 4 decades. if you use a mirror you still wont get it right. Get a bike shop or a guy who knows what he is doing to set you up.
Most importantly don't get the guy your buying the bike from tell you what you need he may only want the sale. There are guys that just fit bikes are are good at it they will also advise you on what is suited for you before you waste your money and get the wrong thing.
Stack reach are important but getting it slightly of isn't the end of the world some people think it is. I see so many people so poorly set up because they just don't listen or understand.
Especially when it comes to simple things even fitting a helmet.
I personally couldn't ride a bike that has a small stack. it wouldn't feel right but some people love it that way. this is were preference comes it.
But good video .

Thanks 👍🌹👍🌹🙏🌹

Goddayumn that bike look sexy af

I don't have a bike to do this on... lol. Was hoping for a rough way to know the gist, before going to a bike shop that might be far away. There is meaning your inseam so I'll look further into that.

This is so complicated

Do fitters help you find bike make and models that will fit you? Do they have you sit on an assortment of bikes and adjust the seat and reach accordingly?

Whay about wight is it mutter or no? I mean if someone wight 130kg is it ok to have road bike 🚲?

My commuter bikes are built out of cast offs. That spare frame that a mate has. Theft is rife where I live so build cheap. Problem is being 5'8" (173cm) in a land of giants. I just fit a 56cm. Being short is shit.

I have such a dilemma
I have been riding a specialized dolce size 54 however I am 5'3. I find this is too much "bike". I feel like it's so big. I have adjusted so many things to make it rideable but I just want a bike that fits me!
I want better handling and I want to get into racing. I want a bike that fits me properly. I am currently looking at a canyon bikes but I think I'm between XXS and XS...?
I don't know whether to go bigger size or smaller size but I want a bike that fits me properly. Planning on ordering online so it's not like I can test drive it 😣😣

Im going to bought my first road bike but its only thumb shifter because its a budget bike, just wanna share
