Bike Sizing using your Biomechanics Information
Вставка
- Опубліковано 16 вер 2024
- There are many ways to choose your bike size when purchasing from you trusty bike shop. One is using the age old template of Height = Bike size. And the othe non mainstream one is sizing based on you unique biomechanics and preferences in riding style
As a GCN Presentor said: "You can always make a smaller bike bigger, you can't make a bigger bike smaller."
I somehow stumbled upon this video. I must say Mr. Cruz had prevented him from making major mistake. 5’7-5’8 rider definitely must choose 49 with 515mm ETT. On 52, a novice or even amateur rider would have done plank on the bike and wouldn’t last an hour before the arms go shaking (he should see Richard Carapaz, Simon Yates, Nairo Quintana). Especially after the covid era, there are really a lot of smarta$$ newbies (including new bike shop owners) acting like physiologist experts / world-team bike fitters trying to give ill-advice about bike fitting, cadence etc etc. This video proved that. Thank you, Mr. Cruz! 👍
Thank you for the wisdom. We appreciate your opinion on this touchy subject
Giving clients assurance is one of the best thing a client can ever have, not everyone can provide a win:win situation.
What a great coach and bike fitter, in this kind of situation we can see how coach Leian is confident with his craft
Looking forward to ride with team crzctrl soon
i totally agree to this demonstration! i have a size 48 bike but I'm 5'8 and it fits me perfectly with minimal body aches even after 150-200km rides :)) hoping to afford the program soon.
Mee too buddy! Same height and same size ng RB tayo.
Some say the bike is too small for me.. well.. kung titignan but I'm comfortable riding my RB lalo na pag long rides :) partida, team rubber shoes lang ako 😅
very true community bike standards are "European" user standards and we are not European's ang liliit natin good job coach
Thank you for watching and the kind comments
Even Adam Yates' 5'7" tall and he's using a XXS (47) frame size for his Bianchi specialissima has a 130mm stem. It's better to have a smaller frame than a bigger one. Just trust CRZ guys
Wow,subrang informative..recommended channel to..
Im 5'8 sir, using a 49 ST, 56TT road bike. I have no proper bike fitting. No budget 😅 using an entry level/budget RB lang :) I can say my RB fits me. How much more kung nakapagbio mechanical tuning pa! Haha!
Nice one coach Lean!
5 10 on the same boat as you 😂 using a elves falath size 49
Hello. Very good and informative video. I personally am high 1.69m with 80,7 cm inseam. I ride canyon endurace in XS size. I was all the time convinced that it's too small for me - it came with 80mm stem. Looking at my colleagues who have long frames, are so stretched, look so pro (ha ha), but don't ride like pro - comparing to them, I look like a godzilla on my small bike. I have even swapped the stem to 100mm and almost slammed it to look better. With the saddle almost all in front (regarding the seat rails movement limits) and with this 100 stem it's ok. But if I try to be more balanced in the saddle, I would have to move it back almost 2 cm, so I suppose the original 80mm stem would be OK too. Recently I bought also saddle SMP Well (newer version of Hell, like on your film) - it has massive range of regulation fore-aft. So I suppose on my frame XS could ride even someone few cm taller than me.
thanks coach
Thank you for the kind words
For me sa reach and stack ako tumitingin sa chart hindi sa top tube and seat tube. Kahit na mahaba ang top tube mo pero ung reach is mas maikli yn pinipili ko.
Coach was referring to effective top tube which I think has a close relationship with reach if ever the bike will be comfortable or not.
here in California just ride the damn bike, get up and go no matter how we look🚴♂️
Hi Mr Cruz hope you doing well just want to know from you that Iam 5.11 guy Iam gonna get a jawa road bike what size do you advise..? Thank you 😊
Never knew that we need at least one size smaller than brand recommended. I made mistake twice. What to do? When you are coming to Sydney bro?
Should schedule a ride there
Im 5.10 ind standard tome was 52 got my self 48 90 stem and adjusted my saddle and posture base on your bio mechanical tuning never had any regrets sprints are o so nice and long rides gave a lot of comfort
Am glad this channel helped on your purchase decision
Galing boss
More power crz Fam!♥️🔥 Hope to enroll soon!
@cruz control. I find all your videos very interesting. Can I ask you your opinion on midsole cleat position? Where does or how much does cleat position come into play whit your bike fitting/biometric fitting. Thank you. Kevin.
Nice informative vid. Coach , can i ask what frame size in the road bike would you suggest for me , my height is 5’4 ft . Thank you and godbless!
For a custom frame, request for a 480mm top tube, if a branded bike with a fixed geometry template, nothing more than 500mm top tube horizontal length
Thank you coach!
Agree its ideal to ride 1 size smaller frame
hi ow much is a custom made titanium bike?
quick question, so sometimes industry sizing is not always meant to be followed and is that the reason why some uci pro cyclists chooses a smaller frame despite being 5'7 above?
The frames are designed for them, they represent the bike sizing measurements that will eventually be sold to consumers
Insta sub!! I have a 47 road bike and i am 5'9. Im just a newbie. I was planning to upgrade my stem to 120 -5 deg. Would that be okay? Thanks. Clicked notif bell as well. I will wait for your new vidoes. God speed!
Wow! That is a super expensive bike even when compared to Canyon! Though I think there are other available brands with geometry that fits better people with short torso, like us Filipinos.
I personally own a Factor O2 and I do agree that its geometry will not fit most cyclists (short torso or low flexibility). It has a very short and low head tube made for aggressive positions. I would always say to anyone just starting out, is to get a Giant. It is relatively affordable and it has a compact geometry.
@@minsansiklista I've tried a dare (can't remember the model) with 48st, 50.8 ett, which is very comfortable. They have models with very good geometry.
@@juandelacruz5247 I have seen a few Dare bikes and I think they do have good geometries as well, although, if I'm not mistaken, the prices are on the 100k mark, so it wouldn't be my first recommendation but they're nice bikes, good looking too.
Try women specific brands like Liv Giant. Shorter reach, taller stack.
Hello coach Leian. Bike size…is it calculated from center of head tube to center of seat tube? I’m asking because there is so much contradicting info on the web that it is so confusing.
Thanks for your time.
oranza is five foot ten .. he rides a small frame
Nice video. Coach I’m 5’6”. What would be the size of my bike?
first coach! love ur vids!
Coach I live in Tennessee I have 9 sworks bikes they are all small frame bikes 52cm . I'm 171.5cm in height and and my inseam is 31.25 inches. My crank lengths are vary from 165cm to 172.5cm. My average seat height from center crant to center seat height 708mm to 715mm. Do you have any good advice to help me to improve my fit. Climbing is my biggest obstacles.
I love your expertise
Can you give me one😭
@@kianderoxas646 I have a frame for sale
no money😭
Lodi ko po yan 😊
Hey Coach, I have been wanting to switch to a road bike. What size would you recommend for a 5'4 guy? If you could answer that'd be awesome.
Hi chris how are you. I can only
Provide you a guestimate. But assuming you have the physical attributes of a Pinoy, select a Bike with a Horizontal Top Tube length of 50cm. Remember it is horizontal. Then pair with an 80mm stem. I hope that helps
ahhHHHh.. Coach Ian please help me a bit Im purely newbie and just purchased a bike that is size 49. I'm 5'11 not so tanky like tank but not stick thin. 92kg-ish.. with inseam of 78.5cm (no shoes etc.) Would it be ok to do adjustments with other parts like stem, handle bar, saddle height fr aft, crank arm or change the frame then start bike fitting from thr? advance thank you coach if you could give me some advice, more power to CRZCTRL!!
Send photo, will give us a better visualization
Boss Ian🎉🎉🎉
Hi coach, awesome informative videos that you have. I'm 6ft tall. Is a 56cm frame okay for me? And what stem and handlebar length should I be using. Also I won't mind traveling to see you in person. Where are you based? .... Will love from Nigeria ❤️
How are you. An episode for a 6ft 2 student will come out this week. Check it out and let me know your thoughts. He was also provided a 56 cm frame. And we had to fit him. The story might give you ideas
@@CruzControlPH thanks for your prompt response.
Hey coach, I'm 5"8 ½ and my roadbike is 48" cm seattube and 50" cm top tube... But a lot of them say I need to buy what my inseams measure (im 50 inseam btw) but still I'm comfortable with my ride.. just asking do I really need to buy what my inseams measure or not?
Hoping to ride with you guys if you visit in davao ..
Hello, good to meet you here. First I wanna thank you for supporting our content. For your question, it is true that Bike sizing for ready made, ready to ride built bikes use the inseam as a reference. Hence the Sizing sticker shows the seat tube length.
If you are local, or can we say, Filipino built and proportions, our main concern will be the Top Tube length. This confirms what you just discovered on your own - your bike fits you. Simply feel if you can reach the brake hoods comfortably without experiencing numb fingers on long rides. This is the usual deal breaker. I hope this simple answer helps
Coach do you have a video where your client is 6ft or taller?
I will publish next week a customer who stands 6ft 2 and another customer at 6ft 1. The visual presentation may help everyone grasp the idea of alternative solutions to a common problem
I'm 5'2 , can I ask what frame size should I choose?
If buying off the shelf ready made frames, maximum top tube length (horizontal) 50cm. Pair with 50mm stem
@@CruzControlPH Thank you couch
coach, I'm 170cm and love to go for endurance type of riding. what top tube size you can recommend? thanks
Will need your floor to Sternum measurements
Ronald Oranza is 5’9” using xsmall
Hi coach. What if mtb? Im 5'8 using a 29er bike. Can i compensate the lenght just by shortening the stem? I switched from 80 to 50.
Yes you absolutely can
Hello po tanong kolang Kung sunpeed Mars V2 Ang bibilhin ko na bike 5'2 Ang height ko anopong size NG sunpeed Mars V2 Ang bibilhin ko?
do you make titanium gravel bike?
Like me I'm 5 foot and 8 inches with a medium size body. I'm planning to buy my first bike which is a gravel bike and when i asked the bike shop which size is for me they said frame size 53 and I'm stuck to choose between 50 and 53 gravel bike size. Is it okay to buy a size 50 for me because they have no size 49?
Yes
@@CruzControlPH thank you very much po for your answer. Your youtube videos po truly helps people like me! Keep safe and God Bless!
Hi, just wondering what size bike you would recommend for a 5ft tall female rider? I have struggled for years trying to find a bike small enough. I currently ride a size 47, and have changed the stem and handlebars to reduce the reach as much as possible without effecting the handling too much. It is extremely difficult to find bike brands that manufacture size 44 frame bikes. So interested to hear your thoughts.
I use a size 42 just to fit me. And allow me to ride above my limited skills
Gosh, I haven’t seen a frame that size here in Aus. Smallest I’ve seen available on order is a 44cm. :(
The WHEELS ON THE BIKE GOES ROUND AND ROUND
Just a joke hehe
Idol lagi ako na nonood sau kase hirap dn ako sa mga ahon ang prob po nang hihiram lng po ako bike kase po 1 week pa lang po ako ng riride
Enjoy that bike. Enjoy the moment
I dont see why not have e the stem at -6 if its a perfect fit and length and all.
You won’t see it because the video is just a clip of a bigger solution that took many factors for the client that had to be considered. The videos take the boring stuff away or it will drive the viewers of this channel away. What the episode highlights is the end result of the person riding the bicycle. We have not discussed openly how his stem height will change as his lower back muscles and core adapts to his conditioning program.
Im 5'6 and half cAn 49 size fit me
Sir tuwing kailan po kau nasa tagaytay or sampaloc? Gsto ko po kase sana makasama lang sa ride nyo sa sampaloc or kahit pa pictures lang po😁
Fridays and Saturdays. See you
I'm 5'10 and my bike is size 48 what's stem is perfect for me??
90 to 100 depending on the headtube+ spacer height

Feel free to leave a comment. Thanks for finding our UA-cam channel
Coach I like your sticker hope na mabingyan mo ako.😀
Of course
Coach 5'3 ako ano size tama sa akin roadbike? Ng babalak kc ako bumili ng roadbike. Salamat sa mga lessons. Malaking 2long lalo na sa akin."whole stick"😅
hi coach, when you say size 49cm frame .. that means it has a 50 or 51cm top tube, am i right? thanks again
Yes
@@CruzControlPH and that is where some bikeshops might be misleading their clients by not telling them that a 53/54cm top tube frame is clearly too long for a 5'7"/5'8" rider .. (hehe)
@@attybong tbh, they are not really aware.. The basis of many people in bike fit is stand over height like in case of bike shops which is just wrong.
@@juandelacruz5247 they are in the business, so they ought to know
go to forward motion guys
I just saw a chubby pogi boy wearing a white and black jersey 😂
Pwede po mag p tuning how po?slmat
Coach kapag 5’8 ano recommended niyo sa al3 domane 52 po ba or 49 na size
49
I’m 5’2 my bike size 53
Sir, is it okay ba for a 5'10 guy like me to ride a size size 52 bike frame, I tried putting a 110 stem to make the bike bigger kaso ang sakit sa may pagitan ng thumb at pointing finger, what can you suggest, coach? :)
If you already own the frame, the optimum maximum TOP TUBE length (horizontally measured) must not exceed 52cm. Now if your frame sticker size says 52, the top tube most probably will be 54 or 55cm. Then you have to change to 60mm stem
@@CruzControlPH na measure ko na siya na 52 yung top tube, pag ganito po coach? What else should I do? Though napansin ko na pag naka gloves ko dun siya nasakit now, pero pag wala hindi naman nasakit kaso nadulas
Hindi po ba twitchy ang 80mm stem pag mabilis na ang takbo po?
From our many experiences, we never encountered this phenomenon. I personally use a 50mm on my Time trial bike and still allows us to downhill at 60 to 75kph like on rails. Same with all the other riders. But what makes this possible is adapting your riding style and technique, by also shifting your center of gravity as well as removing the hand grip pressure on the handlebars that is usually caused by too long of a top tube and stem. The weight in front is what defines the ride characteristics of a bike. Imagine a motorcycle, the handlebar is literally attached to the forks with no 100mm stem. Yet a sport bike and speed up effortlessly in a straight line with little hand feedback
@@CruzControlPH wow ! Thank u so much sa explaination sir kc marami kc nag sasabi sakin pangit pag short stem sa roadbike,pero sa sagot mo sa tanong ko sir mag subscribe na ako ehehhe salamat po
Can I request for a ride to Abra
Never been there. Good bucket list or must destination
Can I join your ride later idol!? I watching you always you help many bikers every vlog, and someday I see you in person
whats up bro.
coach is it safe to say that if a person is buying a built road bike, buy one size smaller than what is recommended using the height as the basis right?
Not necessarily, preferably ask if you can test ride. Feel the bike. If you can’t reach the brakes, perhaps that’s a simple test. Individuals have different torso to inseam ratio
@@CruzControlPH thank you coach
🐱🏍🐱🏍🐱🏍🐱🏍🐱🏍🐱🏍
Coach my bike's effective top tube length is 52.5cm.
I am 5'7". Is the bike fit on me?
I honestly can’t say for sure. You’re torso length will determine the effectiveness of the bike’s dimension. If you have time, watch our next upload about an individual who stands 6ft 2 inches and the bike size that was totally and insanely opposite to what we recommended vs the industry standard that was given to him. The visual presentation will give viewers an idea how many solutions can be applied to a common challenge
@@CruzControlPH understood coach. Thank you po. Always watching your videos at inaapply ko siya sa ride. Very useful po lalo yung about sa climbing posture.

48st / 52tt?
Thanks. :)
Ikaw nalang mag company kasi mali pala mga sizes nang company
Test ride the bike. Feel your purchase. You worked hard for you money, make sure you can hold and reach. If a bike shop has a test size bike, ask to ride it even on a trainer. Just don’t get what is shoved into your hand
Di naman sinasabi na mali lahat ng company, ang point dito, hindi applicable sa lahat ng tao yung sizing ng company kasi iba iba haba ng lower at upper body ng tao.
@@gabrielnavarra1193 yan ang mga tipo ng tao kasi sir na mababa ang comprehension. Hindi muna nakikinig mabuti at iniintindi ibig sabihin ni coach. Kaya magcocomment na lang sila non sense. Haha
Hehe yun mga company kasi gumagawa halimbawa ng isang bike na magffit sa difeerent height ng tai. Marketing strategy nila yun para makabenta, yung ginawa ni coach pinili nya yung angkop talaga sa body mismo ng rider.
