Fitting Your Bike Are you confused about how you should fit a bike to your particular body dimensions? Have you been reading, found the terms Merxx or French Fit, and don’t know what you need? Every style of riding is different- in how you fit the bike to you, and the sizing of the bike itself. It’s more than just measuring your height, reach and inseam. With the help of Bike Fitting, you’ll be able to find the right fit for your frame size, style of riding, and your particular dimensions. Here ya’ go…..the location for everything fit related.

Lightbulb Old bikes fit vs new bikes (any difference?)

Hey guys! I have a question, Im 1.91m and im riding a 63st old road bike, today I was in a shop looking at some new bikes from a well known brand, (can I tell names?) and I asked the guy if they had 62 or 63 st size bikes, and he said that by the catalog with my height I should be riding a 56 to 58 bike, and that a 58 would be too big for me.
What do you think about that?
What is the size that I should look for?
Tomorrow I will take some mesurements again and I tell you all the numbers that I got in the fitting calculator, I don't remember all from the last time I've check, just know that it gave me 61 for competition fit, 62 for eddie fit, and 63 for french fit. I think I've took all the mesures right.
Thank you guys!
Happy cycling for you all!

Most current road bikes have sloping top tubes, so the "seat tube" is shorter, and the seat post is longer, than for traditional horizontal top tube bikes.

The way newer road bikes are sized can be confusing (I have been learning this a lot as I shop for a new frame). Most old bikes did have a horizontal top tube and now a lot have sloping tubes and compact geometry which means that the actual top tube length can be deceiving and you must go by effective top tube or virtual top tube. Also a lot of companies frame size has nothing to do with the top tube or seat tube measurement. I just read a good article about this (of course I didn't bookmark and can't find it now). But they pointed out how one bike's size was 50 but the top tube was 545mm and seat tube was 520 so it was really like a traditional 54/55 size bike. So yes, sizes are different and if you are shopping at an LBS let them size you and suggest what size to buy

need more data for comparison.. seat tube/post angle.. head tube angle .. virtual top tube length (so slope doesn't matter) its a horizontal line .


then there is the rider preference .. young go-fast .. you see short frames so the bar tops are low, so posture is down on all 4s like ..

Tourist types you would want the bars higher and closer to you, and may even wish the mass assembly line build

did not include sawing off the steerer with out ever letting you decide what was right for you in the first Place..

Thanks a lot guys, you really know a lot about this, Im always learning with you. Im reading a lot in the web, but sometimes its difficult to have a strait answer. 3 days ago I was in a shop looking at some bikes, they are all expensive, the cheaper one was about 700€ with alloy frame and carbon fork, the components weren't good, no brands the wheels were from a brand that I've never heard of, and the cubes didn't have any brand at least the front one didn't. It was a merida shop. I just thought to myself, why???
Why should I buy a 700€ bike that is made by a machine and doesn't have any craftmanship? Is it faster then my 79 gitane? Lol I think it is not! At least in my gitane I have campy drops, and a cool reynolds 531(only 3 tubes reenforced)
I think Im going to keep buying old bicycles and old components, at least they have some spirit, and a frame made by hand means more to me. I have 2 bikes in sight now, a Houissoon Sport frame, reynolds 531(full), campy drops(rear and front) and bb shell from Cinelli, even the rear brake bridge is campy, first one I see, at least look like it, says Brev... Something that I can't read.
Second option, a colnago with campy set, Im looking for her, I like them from the 70's to the 90's, have to search for them.
What do you think?


Thanks guys!


Good weekend for you all!

Bicycle frames are still handmade.

It takes a factory to make the components , the frames can be made one at a time by an individual person.

though to lower the cost the factories make big batches at once , and seek a person to cost less to do the job somewhere cheap .

Portugal is a lower cost place to make things than Germany , but at 700€, I expect the bike to be imported from a huge factory in Taiwan.


a few factories there, Merida is one, make most of the world's bicycles . under various brand names ..

To me a well fitted classic road bike is a great ride and has an aesthetic appeal unlike the plastic pop bottles sold today. If you are riding recreationally they work perfectly well, are easy to maintain and can be very cost effective. Most of my miles this season are on quality machines that are decades old and still in service.

Good modern kit does have an advantage in competition, for spirited club rides and challenging conditions.

The C&V sub-forum is very active w/ lots of info on the Classic machines.

As far as fit on a classic goes research "Merckx Fit" or use the Guimard/LeMond system, it's not a plootering about fit but was/is very effective in competition over long distances and lousy roads and works just as well today. "French Fit" if that sounds too demanding.

A good friend of mine who works in a local chain of bike shops put it like this. The big bike companies have different ideas of how their bikes should be fit. Your numbers could mean very different frames for the different big bike companies.

I think a good sizing is any frame that allows you to get all the contact points where you need them. Seat tube alone or any single size number is not enough to guarantee that.

I don't understand why the bikes are not made for each rider like back in the days when each rider was mesured and the frame was made for him, everyone is different but the bike brands have arranjed a way to make every bike fit everyone without mesurements, the goal for them is just to sell, after that you are on your own. At least thats what I think.

I like the current frame design philosophy a lot more:

1. more standover clearance

2. longer top tubes

3. longer head tubes

Generally speaking, bikes today have top tubes which are .5 to 3 cm longer for the same amount of standover clearance. I have actually found several models which actually do fit me now, which would have been more or less impossible 25 years ago, without custom geometry.

The industry has been responsive to it's customer base (as the price of bikes and component groups has risen, the average bicycle buyer is generally older, less flexible, and heavier than 20 years ago).

I still think the cycling industry has a long ways to go in terms of improving shifters and brakes. But in terms of frame design, the industry has done a lot of things right.

The same reason clothes aren't custom made for everyone - expense. In much the same way you can have a suit custom made by a tailor, you can have a builder completely custom make a bicycle for you. But it will cost, dearly.
