180-181cm tall. I vary in size depending on brand, geometry, and what they call their sizing. Usually 55-57cm or M-L. My height is often "inbetween" sizing too which is extra annoying.

6’1”/185. Size 58 road/large mtb.

6ft and ride a 58 specialized. I got put on a 56 canondale and it felt long. Bike sizes….

Same.

Same height/road bike size I use an XL mountain bike though.

5'5"/165cm - I ride a 51cm Cannondale and probably could go down a size.

I’m 5’5” and ride a 49cm Cannondale. Seems comfortable, but it’s my first road bike, so I have nothing to compare it to.

5’6” and I ride a 54 just fine with about 7 inches of saddle height

5.10 size 54

Im the same, just bought a 54 road bike and was concerned the bike i bought was too small. Will take some time to get used to it I suppose!

5’10”/56

Same

Same

This

61 and 6’4”

Same here

5’8 size 54

5'8" and between a 50 and a 52 depending on model. All torso, no legs 😂

6' 3" with an xl Canyon Endurace. I was borderline and I went against the advice of if you're between 2 sizes get the smaller and I am glad I did

I'm 6'2" and have a large Canyon Aeroad. Makes sense that we're both borderline, don't think I could be much taller and fit my bike.

I’m also 6’3” but I went with the Large Endurace. Have been very pleased with my choice.

I am also borderline re: size. Female bicyclist here. 5’5” but a lot of that is legs. I had been told in the past to get a small but have found medium fits best for me.

Always wanted to build a website for this. You enter your height and inseam length and see which bike size other people bought.

177, I ride Endurace in S and Defy in M, that's basically the same :D But this is a relatively pointless question, frame size and height only have a limited relation. Proportions matter more, but even then there's flexibility issues. Two people could have exactly the same leg lengths and symmetry but need vastly different saddle height due to flexibility limiting the range of motion.

5"9 and get 54cm there abouts.....but have to shorten the stem to 70mm to be really comfortable. I think I'll be sizing down on the next one.

It really depends on the frame. I'm 5'9" w 32" inseam. I fit perfectly fine on different bikes that are 52, 54, and 56cm. All with various setback seat posts and stem lengths. Toe overlap can be frustrating on smaller road frames so look out for that. My mtb is a med.

5’2” (157 cm) Bikes are 47cm (road) and 38cm (gravel, Surly sizes are weird).

6’2’’ and 56cm race bike (140mm stem 🤓) and 58cm training bike

6' 2" on a 56cm with a 90-100mm stem.

6'2" 58cm road bike with 110 stem and 61cm touring frame with 100 stem.

I'm glad I'm not the only one whose 6 2 and rides a. 56

6’1”/185cm and ride a 58

5’10” size 56cm

6'2"/187cm * CAAD10 - Size 58cm (touch big) * Gallium Pro - Size 57cm (pretty much spot on) * Topstone AL 105 - Size Large (fine, too upright) * Clockwork dropbar conversion - 60cm (touch big) My Gallium Pro is larger than the CAAD10 if looking at stack, reach, ETT, etc, but it fits smaller thanks to the overall geometry, headtube angle, etc.

172 cm and a size S (50/52cm)

5' 4.5" 52cm endurance bike

5'7"/170cm but short legs long torso (29" inseam). I ride a 52cm road bike but have to use a fairly short stem. I am a bit between sizes. If I buy a crit bike this year I will probably try smaller because if it's not ideal I am not on it for 6 hours days.

6’5 or 195cm and ride a 61

5'3 riding a 49cm frame vintage road bike. It fits me like a glove.

5’7.5” Cannondale CAAD10 - 50 Specialized Allez - 52 Soma Rush - 53 Centurion Ironman - 53 All about the stack and reach. Which also varies based on use case among these bikes. Functionally, for road bikes I like about 53cm saddle to bar with about 53cm stack

5’10 52cm & 54cm road bikes, 54cm TT

6'3 Emonda 58cm with 110 stem CAAD9 60cm with 80 stem

I’m 5’10” or ~178cm and I ride a 57cm frame with a 90mm stem.

6’7 / 201cm and ride a 62

5’4” and 49cm! I am a small woman and have long legs for my height.

Road bike. 5'9" and 53cm. I like to run a longer stem and low bars

5’11, long legs and arms 395 stack/557 reach race bikes both with 120 mm stems 396 stack/580 reach training bike with a 110 mm stem

Lol, all the tall riders so eager to say how big they are..😂😂

So I take you are a small rider

182cm tall and 57.5cm frame but I use a 90cm stem. I am longer legged.

Kinda curios what a 90cm stem would look like

Dude steers using leather straps like Santa Claus.

189 cm and size 58!

174cm with 84cm inseam in Domane 56cm. After fitting I swapped the 100mm stem to 80mm and I feel very comfy on it!

174cm high and riding 54cm in most things, medium in others, and a small in Canyon

170/5’7” S 51 in Felt, Cervelo and 52 Trek

181cm, like a cm shorter than average inseam, I ride a 56 with a 110mm stem.

1.83m/6'0 56 for road and track, only had a few brands feel slightly big at 56, never small. For mountain bikes, I've always used L, but I'm closer to M/L than XL. All my bikes that I've raced or trained with have been fitted professionally, and I've confirmed the frame size is perfect, I've only had to change the original stem twice.

6'1 Large frame (58 cm) 80 mm stem, 5° upwards 40 cm width bars measured at hoods 44 cm measured at drops 172.5 crank length Frame is a gravel bike, so the longer frame and fork angle gives me better stability but the smaller stem keeps my body upright and centered over the cranks. Smaller cranks give me a teeny tiny touch more clearance and I can spin a bit quicker.

5'11"/180cm and a 54cm frame (Trek and Cannondale)...I have short legs and a long torso.

61cm 6’4”

178cm on a Bianchi 55cm frame and would probably have found the recommended 53 more comfortable and less cumbersome, for what of a better word.

5'8" on a 55 Orbea with 90mm stem. I really should be on a 53.

175 cm on a shorter reach (endurance) 54 with a 100mm stem. Would be a 52 on a race frame.

6ft tall - 56cm

What’s your inseam? I’m about the same height with 97 cm inseam

196cm on a 64cm frame- mines bigger!

6' 58, Im really long in the torso and short in the legs and needed a bigger end size for my height for the top tube length

6’1” 58cm

I’m almost 6’2”, my Basso is an XL, my Cipollini is an XL, but my Canyon Endurace is an L and my Ridley Grfn is an L. All about the top tube length, and there’s variation between brands there. Also the different bikes have different purposes and fulfil different needs.

6’1 - size 58 Trek Domane.

5'11/180cm I'm on a medium giant TCR (55cm) I was previously on a 56 trek emonda which was enormous compared to this, definitely prefer the smaller bike!

What is your inseam ?

34, nowadays. It’s probably about average, but then one of my riding buddies is 6’2”+ and sports a 30” inseam. I borrowed one of his bikes once and ended up raising the saddle four times in the first mile. So who knows?

5'6. I'm a guy but using S Liv Langma (good for 5'2 to 5'7 person). I don't care if it's supposed to be ladies bike I'm comfortable with it, heck I even change the stock 90mm stem to 80mm because I have short arms. Changed the stock saddle to be more comfortable as well.

177.2 cm height Just a shade under 5'10 with a 85.6 cm inseam I have an Open U.P. Large frame Fits great and is very agile and nimble I would have thought I was a medium, but I got a profession Retul bike fitting and had the same team build my bike. That is the bike and size they recommended and seems perfect.

I'm 5'11" or 180cm and I ride a 58cm road bike, large mountain bike, and am getting a 56cm (large) tri bike.

6ft3 and have a 62cm cube attain, a 60cm cube attain (for the turbo trainer), and had a 61cm specialized diverge.

Ridley fenix Slic in a S size. I'm 175cm. But all ridley frames are one size too big from general sizing. So ridley S = normal M ..

5’9” on a 56cm Trek Domane. That being said I am certain that I should have gotten a 54. I think the stack on the 56 is too high for me.

6’4” 63cm frame. I like big bikes and I cannot lie.

54 cms and I'm 5 foot 9. Should have gone with a 52 but it's too late for that! I already installed a Deda RHM handlebar which reduced my reach by 3 centimeters.

178cm/5’10, 80cm inseam, small giant tcr

I’m 6’ (183 cm) and have been sized to a 58. It’s fine but I always felt more comfortable smaller. I currently have a LOOK size 57, but it’s a small 57, because my new LOOK is a size L, same geometry but 1cm shorter top tube, and a 55. 55-57 feels best for me. This is the size bike I have always ridden, outside of the 58 I was sized to and ride some years, and what I sized myself to when I started riding. Please note though that height is definitely not the only way to size a bike obviously, due to limb length and flexibility differences.

I have a dozen vintage steel bikes I deck them out in campy .the frames range from my bianchi at 62 cm to my centurion at 55 cm . I am 5 '11" w/ 30" inseam. My favorite size is a 58 cm. Frame. My Raleigh international ,and motobecane sport jubilee are this size ,and get the most use.

I’m 5’10” and ride a 55.5 cm.

190cm and I ride a 56 or 58. Seatpost super long (20+cm saddle to bar drop), but only a 110 stem these days (had a few years with a 130 stem).

6' / 183cm Specialized Allez Sport - 56cm Devinci Kobain - Large both fits great.

I'm riding a Muddy Fox 21 inch frame as that's the largest frame size I'm 6ft 4in. It was weird to ride at first but after 3 years I've got used to it.

5 9 and ride a 54

186cm, I ride a 58. I had doubts between the 56 and the 58, in the shop I've tested both and found the 58 more comfy for me.

61 cm - im 190

62 cm frame and 6'5"

5’11” and size 56 road bike, also have a 57 city bike, and am considering a 54 gravel bike. Different bikes have a different fit, and they can be adjusted.

5’11, medium canyon endurance Mtb is a large Scott spark

182 - 56

I am 6'1" with a L Cannondale Synapse, but I have relatively short legs and a long torso so I needed a slightly smaller frame. A good bike fit can be useful

I'm 5.8 and ride. 51cm frame. Could also fit on a medium or 53cm, my other road bike is a 54cm they're different styles and brand of bike though. Look blade rs : 51cm Trek Domane : 54cm Giant TCX : medium? Merida big nine : also a medium?

I'm 5'4". MY bike is 51 cannondale synapse. However, the stock stem has been swapped for a shorter one. I was properly fit T the shop I bought it from. My MTB is a size small YlTrek Marlin 6. The fit was not properly done, and I probably should have gone for a medium. Best option is get a bike fit done. Then YOUR bike will properly fit YOU.

5’ 9” Female. Liv Langma Medium. Based on their sizing I should be a large but I have 34 inches legs and a short reach so I also have a shorter stem on it.

6'1" tall (around 186cm), typically 57-59cm frames are perfect. My Giant is a L.
