Gravel bike sizing ?

[ChrisF]

Looking for some guidance on gravel bike sizing, please.  I am 1,75m.

 

At first glance, similar to MTB -

 

 

 

Not surprisingly, like my other Giant products are also M.

 

Certainly very surprised with the Merida size chart.  Either on the upper end of S, or just on the M range.

 

 

I note that Hub classifieds use cm sizing .... no experience with this ....

M or 54cm as a guideline

Impossible to say. Your individual dimensions will dictate. I'm 175cm and a small Giant or an extra small Merida work for me. Speak to your fitter for advice

I’m 1.75 m tall and ride a medium Revolt. But pretty sure a small frame would work for a more aggressive setup, as my seatpost is not very far extended (I have short legs). This makes for a relaxed drop to the handles, even with the stem slammed.

As mentioned, rather speak to a good bike fitter beforehand, as total length does not give the full picture.

Seems I am having coffee with Irma ....

 

 

My first full suss was a balls up due to incorrect size ...  dont want to repeat that nonsense ....

Just to add more to your confusion.

I ride a Large merida 96 MTb

a 54cm road 

a 56cm gravel with shorter stem. Although longer than my road bike it is a lot more relaxed fit than my road bike. Stem being higher and saddle to bar length almost the same. with gravel you don't want to be TO nippy. 

 

for clarification i am 1.79cm so i sit on the M/L threshold. at 1.75 i would go smack bang 54(M) and tweak the setup with stem length and bar width.

Im 177 and on a 54 gravel bike.. it fits well but richard did say i would actually be ideal on a 53.. slightly bigger is better to fit than slightly too small..🤘🏻

Just noting that sizing between brands (and often within brands between models, or even years) is a complete dogshow.

Example, comparing 2 different years of Spez Diverge to a Trek Checkpoint, all ostensibly size "56"

Geometry Geeks is your friend here, work out what your desired stack and reach are and then find the size that most closely matches that. If between, size down.

I fear this resource is going to consume my life.!🤦‍♂️🤣🤣

Bra don't get me started. I use that site at least every 2 weeks as I go down my illogical dream bike rabbit hole, may it be gravel, road, MTB or even monstercross

Im properly excited, and a bit frightened if im honest🤣🤣.. 

also side note, i read your UN as “PappaTw@t”.. 🤣🤣 sorry had to share that cause it amused me..

I am 177cm and find the M Giant Revolt fits me well.

Although I could in theory stretch to a M/L, I preferred a medium stem so that I could add a Redshift shock-stopper that I had already, but also a longer stem is more stable and less twitchy. I have a Pyga for mountain biking and use my gravel bike on gravel roads. 

If you are more inclined to single track and picking your way through difficult stuff (i.e. towards the mountain biking end of gravel), then longer reach,shorter stem, wider bars may be better.

If you prefer long-distance bombing down gravel roads and ultra events, then shorter reach and longer stem may be more stable, less taxing, and more efficient.

Keegan Swensen is my height and on a small Santa Cruz with a long stem for ultra events.

Will save you much faffing. If she's already got your measurements she may even be able to recommend based on TT length or reach.
