Hello all!
I'm currently looking at the Canyon Grizl aluminium, really beautiful bike that I like.
For my high which is 5.9 (176cm) they recommend size S. But the stack for size S looks like is very low, just 55cm. Is that to low? Would that put me in a racing position? For example Fuji Jari 1.1 in my size, has a stack 58.

Yeahbut your Fuji probably has differing frame dimensions so I would carefully compare the two to see if the Canyon would suit you. Suspect they might not be too far apart.
Thats the problem with bikes you can’t try.

Alternatively go to a shop that has a bike jig
They can set it up exactly as the canyon and you can see ( sort of) how it fits you ....the downside us it will cost you but the bike frame seat headset bars etc will fit you perfectly and have no strains on your body

Go to your local Giant store and sit on one. Thats the only way to get a guaranteed, credible answer to those questions.

This is the prob at the moment stocks are low causing us to buy mail order or used , blind . I recently thought I’d found a bike that would do my needs , the doing the maths the geometry was strange , it was a 51….turned out it had a reach more similar to a 48 and a stand over height more like a 53 , but it also seems that all 51 are different depending on manufacture , there is a website called geometry geeks I found that useful, helped me along with visiting a few bike shops , to do the maths

Make sure the crossbar suits your body length as well. I've got a small second bike that I can ride because it has an extra long seatpost and stem. Unfortunately the short crossbar means that I can't lean forward and pedal efficiently. It's harder to pedal uphill than my other bike even though it's 2kg lighter and has a 4 inch lower bottom gear.

I don't know about elsewhere, but out local Giant store has everything, including its demo fleet that won't be sold until the next years models are released.

Do Giant stores in U.K. sell Canyon bikes? :scratch:
I was also wondering why Giant came into the thread 😂

Gravel bikes are a fairly new addition to the ever increasing specialisations that form our beloved hobby. As I was in the market for a hill climbing tool, gravel attreacted my attention. So, after a little research I found that manufactueres come at gravel from many angles... Some take a road bike, margially lower the gearing (compact front and 11-32 or 11-34 at the rear...) make the forks and chainstays fatter tire friendly and call that a gravel bike (normally with a 30% premium over the original road bike it came from..)..

Others have stuck with the road bike origins but have properly looked at the gearing and gone to GRX or SRam gravel options and made a bike that is different from a roadie. These bikes bode well for us old farts that need lower gearing just for normal life. I found that Merida took a different route with their Silex. They basically took Mountain bike geometry, so the front is high, put on 38mm tires GRX (for the upper models (Sora for the base..).

Check out their website and look at the geometry, its very intersting and for me a good way to go for gravel. I wanted a Silex 400, with bottom of the line GRX Groupset, but sadly in my size I would have to wait well into next year or even 2023... but a shop in Taipei found me a Silex 200 that had the Sora Groupset, I paid a little extra to change out the front rings from 48/32 to a 46/30.. that gave me the gear inches I wanted. I would have prefered the GRX, but I get the same frame, wheels etc. for 250 quid less.. Riding position is more upright than other gravel bikes I've sat on, my seat and bars are at the same hight. Very comfortable and way better gearing for hills than a road bike.

I may.. have lost track a little with the above post.. more specific to Canyon I also considered them and followed thier instructions for sizing... im like you 5'9" and 30" inseem... their computer told me Im an odd shop... I changed my inseem to 31" and it also told me I was S.. I'm M in every other make I've tried. That put me off a little as shipping to Taiwan isnt cheap and if it didnt fit I would be in trouble.

On the subject of Canyon, my daughter bought me a Canyon Urban as it was left over from a photo shoot so she got it cheap.. it's XL... she thought as I was XL in everything else it would be OK, the dear poppet even boxed it hereself and took it as luggage to Malaysia... It's a thing of beauty, and very well made with lovely companants, hub drive and belt instead of a chain... but monstruously to big.. so maybe there sizing is correct...

You really need to sit on a bike and feel it. BUT
im a Small if bike shops advise me , but as said makes models all vary , if I was buying a bike blind
i would look at the reach , and stand over height
I like to touch the floor flat footed over the cross bar . And not feel to cramped on the reach , which small tend to me for me . Look at the geometry, ( geometry geeks ) sit on a few bikes in a LBS then compare
