Frame size, new bike fitting, questions

Hi everyone,
Hoping you could help me with sizing for a Colnago C64:
Height: 165 cm
Inseam: 81 cm
Saddle height: 72.2 cm
Current setup:
Reach: 380mm
Stack: 538mm
Stem: 90mm
Spacers: 20mm
Colnago says I should be on size 45s but I am worried that I will need too many spacers to make it work.

Hello everyone,
I'm thinking of getting a BMC Teammachine SLR01 and I'm not sure if I should go with the 47 or 51.
BMC's size advisor indicates a 51.
I currently have a Cannondale Supersix EVO size 51 with a 100mm stem and I feel stretched sometimes, even if I swapped the stem for a 90mm one I'm not sure it would be enough.
Height: 167 cm
Inseam: 76.5 cm
Current setup:
Reach: 379mm
Stack: 522mm
Stem: 100mm
My flexibility is not awesome, I can reach the ankles but not the toes. But I want to improve it.
What size do you think it would be best?
Thanks in advance.

Hi All,
Been given the green light to upgrade my old 2015 Tarmac Sport 56 & thinking SL7 as I enjoy that bike but fancy some bigger tyres & disc brakes now.
I'm 1.78 tall with shortish legs, inseam 83cm and short arms. Had a bike fit a pre-COVID when I started cycling much more and I had a shorter stem (90mm) fitted as I was told the 56 was a size too big. Feels good to me now, but might have just got used to it being a touch big, with the shorter stem but I'm not sure on what size as I fall right between the 54/56 according the Specialized
Current Stack 564 Reach 395 & my saddle height is 748. Every decent fitting place near by is booked up for weeks sadly.
Thanks in advance

Hi all!
So I'll be upgrading my bike and turn full roadie this time around
I've chosen the Giant TCR. My LBS has stock of the advanced pro in size M. So in another thread, specifically in the TCR thread, for my height I'd fit a size S better. Geometry of my previous bike,which was a merida silex 400, and medium TCR advanced pro tells me that they almost have the same reach. Majority of the difference would be in the stack since my previous bike had an MTB'ish geometry. Here are screenshots of the geometry of both bikes
Stock stem for the silex was 80mm with 40mm handle bars
My measurements are
Height: 174cm, longer torso armspan of 179cm (is this a thing? lol)
Inseam: 75cm
Saddle height previously: 81cm (inseam x 1.09)
I didn't have much problems with my previous bike in terms of fit and I didn't even feel stretched out (I'm not quite sure if my armspan is a factor here since mine measures 179cm which is 5cm longer than my height). Flexibility is not much of a problem too.
Additional info is that I have not had a bike fit before and figured a shorter 90mm stem(rather than 100) and a short reach on the handlebars would help further in decreasing the reach. I also dont mind spacers that much and I won't be racing. One problem that comes into mind would be the seatpost exposure (is there a minimum seatpost exposure for compliance?)
Hope you guys can help thanks!

How many spacers are you currently running? A 54 would be very very low. At 178cm, I would not go for a 54 unless you are trying to achieve a super aggro position.rangemonkey wrote:Hi All,

I agree. At 175cm I'm stretching the new Allez which shares SL7 geo. I'm on a 120 stem and saddle all the way back as far as it goes. I can't stand over a 56 or I'd go that route.ToileySiphon wrote: ↑Fri May 20, 2022 1:39 pmHow many spacers are you currently running? A 54 would be very very low.

That is a pretty high saddle position for your inside-leg measurement.

Agreed. I’m about the same size and have a 730mm saddle height on a 53x54 frame with a 120mm stem. Saddle tip to bar is 530mm.TobinHatesYou wrote:rangemonkey wrote: ↑Thu May 05, 2022 9:02 pmHi All,

Hi everyone !
I’d like to have your thoughts on a systemsix frame size. I hesitate between a 54 and a 56.
I’m 179cm tall for 88cm inseam (quite weird I know).
I always go for the smallest I can with a longer stem when I’m between two different sizes, but for for the systemsix, I’m not sure if a 54 is just impossible to match my measurements.
Thanks guys !
