Help with Frame Geometry: Leader 736R to Canyon F10

I’m considering going from my alu Leader 736R to a carbon Canyon F10. The geometry is a little different so I’d like to know what to expect. Will the TT on the Canyon be just as long as the Leader which, length wise, fits me very good now. Will the handling be different? I’ll try and give as much info as possible. Lets just say that I will use all the same components save for the fork which Canyon uses.

Leader 736R:
Seat Tube length (C-T)= 53
TT Length (C-C)= 54
Head Tube Length= 100
Head Tube Angle= 73
Seat Tube Angle= 74
Fork rake= 41

Canyon F10:
Seat Tube length (C-T)= 54
TT Length (C-C) = 54.1
Head Tube Length= 138
Head Tube Angle= 72.75
Seat Tube Angle= 74.5
fork doest give rake but I’d guess 43



Components: Alpha Q Sub3 Fork, Thomson Masterpiece Seatpost set back, Thomson X2 Stem -10degrees 120mm, Kestrel EMS/SL Pro Handlebar oversized, 172.5MM Crankset (DA).

Those are the important ones I’d guess. I hope I didn’t give to much info. To be honest, I think I could have used a zero setback on the Leader cause I set a little up only Arione but it works. But I do enjoy setting back on the seat during decents. Maybe I’m putting to much thought into this? Thanks for any info yall can provide!

There is a big difference in headtube lenght. Do you use any spacers under the stem with your Leader?

Do you have the ability to slide your seat back ~5mm to compensate for the steeper seat tube angle? Then the reach will be a little longer as well, so you *might* want a slightly shorter stem... and one with -17 degree might be needed to get your bars at the same height... but if you have no spacers now, then that won't even do it. 38mm in head tube length is the big difference. Is one of them an integrated headset and the other not?

the leader is integrated. not sure on the Canyon. I do have some play on the seat. it can go back more, no problem. I use no spacers on my frame. Only what i need.

BTW, you cannot use the alpha q on the Canyon. It has 1&1/4 lower races.

Look at a smaller Canyon frame if you currently have no spacers on your steerer. Do you have the geometry for other frame sizes?

The Canyon frameset always includes a Smolik Race SL carbon fork, 295 g + Syntace F99 stem (installed), so it's no big deal. The Smolik Race SL fork is the best fork ever tested in the German Tour Magazine.

And actually Canyon F10 frames doesn't have 1 1/4" lower races but 1 1/2" (38 mm). This is the same size as on the new SystemSix from Cannondale.
Who knows, maybe this will become the new industry standard sometime in the future as it helps making the frame stiffer and makes it easier to mount an oversized downtube.

This also led our designers to develop an integrated frame/fork chassis solution with an enormous 38mm steerer tube which conically tapers to 28.4mm at the top bearing. This allows us to use a large lower headset bearing (52mm) to help handle the loads placed on this critical area of the chassis and increase rigidity and handling ability. This integrated approach to a frame/fork unit is the real reason we could not rely on anyone else to design a fork as innovative as our frameset.

Sounds great then... you can ditch a bunch of spacers on the Canyon.
