Frame size, new bike fitting, questions

[silvalis]

The cube ETT looks wrong. Should be 530mm. Rest of the numbers and Stack and reach look correct.
Either way, you're going to have to slide your saddle forward, shorten the stem a bit and raise it up a bit.

Thank you for the advice

Hi,

Im 185cm with inseam 84cm and arm span 184cm. I have this beautiful offer on Tarmac SL6 size 56, but wondering if this frame could fit me.

I went to specialized store and the guy did quick Retul bike fit and suggesting me with size 58 ( i went there with office attire, hence cant really tell the difference except size 56 measurement give more weight to my grip as compare to 58 )

For the reference, i currently ride bianchi oltre xr size 59 ( with 90mm stem and 2cm spacer )

So, would like some advice if i could fit with size 56 with longer stem and probably train my core muscle to be more flex with the position.

Thanks

Was it discussed which parameter in the Retul fit was the deciding factor between 56 and 58?

I'm 180/84 and quite flexible, and I'm riding a 56. As I have my stem slammed, I think I could get a proper fit on a 54 as well. That would enable me to go even lower (I'm thinking I could go about 5mm lower) but I might feel a bit cramped when standing up, even with a longer stem.

Hey there, I ended up swapping that Canyon Endurace size SMALL for a size MEDIUM. Here are the results:

Looks good. Taken it for a spin yet?

Yeah, feels great!

Anyone know max saddle height on 58cm Tarmac SL6 or Allez Sprint, or can anyone attest to running a very high saddle height on one of these?

Yup another frame comparison question. That time of year I guess but I trust this board more than myself sometimes.

54 factor o2 moving to a medium giant tcr advanced.

Is it me or should those two match up almost perfectly. The stem on the giant is 8 degree and I use a 6 normally. I run 20mm of stack on a 110mm stem.

Thoughts from the board Illuminati?

Hi All,

I am planning to buy the Giant TCR Advanced 2 but am unsure of getting "S" or "XS".

My stats: 169cm, previous bike was a "XS" Canyon Ultimate for 166cm to 172cm riders which felt a little stretched for me. I have more legs than torso.
Stack: 522mm
Reach: 378mm
TT: 529mm
stem: 90mm

For the Giant, "XS" for 155cm to 170cm riders.
Stack: 517mm
Reach: 372mm
TT: 515mm
stem: 80mm

For the Giant, "S" for 165cm to 175cm riders.
Stack: 529mm
Reach: 378mm
TT: 535mm
stem: 90mm

Seems like i could go with the "S" but the toptube length is scary at 535mm, my friends have advised me to go for a "XS" and get a 90/100mm stem instead.

Any advice for me? thanks !

Looks like you answered your own question. If you feel stretched on the Canyon you'll want to have to go XS on the Giant. You may need a bit more spacers on your stem.

Forget the xxx mm to xxx mm measurements. Get a professional bike fit before buying a new bike and keep that with you. Use it as a baseline for future purchases. It prevents the guess work when you buy a new bike

PS
Im assuming you live in Asia? Giant seem to have forgetten there's short people in North America. There's like 2 bikes that only come with XS here.

Yes, thanks for the advice, got the "XS", can't slam the stem but feels okay overall, just need to get a 90mm stem soon to replace the original 80mm.

Owning two bikes, Colnago C60 and Cannondale Caad12.. C60 is in 50S, have Deda Superleggero Handlebar (75mm reach, 130mm drop), and 110mm stem. On this bike i have a perfect position...

On Caad12 (52 size) i have Easton EC90SLX3 Handlebar (75mm reach, 130mm drop), and having a bit problems to adjust my position.

i done Rettul Fitting few years ago, and my ideal setback is 52mm, and about 72.5 cm from bb to top of saddle. On both bikes same saddle (Selle Italia Carbonio Flow SLR)

If i go with 110mm stem on Caad12, i feel a bit short bar position....If i go 120mm then is a bit long.. So obviosly i need to move a saddle a little bit to compensate.. If i go 110mm stem, i need to move back 3-4 mm.. If i go with 120mm stem, i need to move 5-6 mm forward..

So what is better compromise? Im 175 cm, 82 cm inseam, my avg cadence is about 90-100 rpm.. Most of the rides involve some climbing.....

This is velogicfit comparation with similar stack:


110mm stem (on Left side is CAAD12, on Right Colnago C60):



120 mm stem (on Left side is CAAD12, on Right Colnago C60):




And this is position i ride in this moment to get a bit longer reach (dont have a problem on Caad12 having a lower stack, but still feel a bit short in the front):




So which way to go? 120mm stem, and saddle in front to compensate longer reach, or 110mm stem and saddle moving back to extend the reach and compensate feeling a bit short in the front?

I could use this info too, same issue

[NordicSal]

I am around 197 cm with around 100 cm inseam, very long arms as well and pretty flexible on a bike at least. Is there any chance I would ever fit on a 58 cm bike, do they make seatposts long enough? Right now I am on a Domane ALR 62 cm, and I have this theory that a more racy geometry will mean a higher positioned seattube, and therefore I might be able to cope with a size or two smaller?
