its the 48cm
and I want the CDF for the rack mount so I can use it for light touring as well as a winter bike. I cant find anything on the market that comes in 48cm size with this spec.
and yes I have been comparing reach and stack, but also from an aesthetic point I dont want just a few cm of seatpost showing..
-
I still cant decide to get a genesis CDF for winter or if going custom is the best route. If I went custom I have no idea what im doing so could end up with a totally shit frame.
to get the CDF to fit, I will have 2cm less seatpost than my caad10 & about a 10mm shorter stem.. My caad10 fits perfect but doesnt have masses of seatpost on show as is.
Do-able?

@mdcc_tester @Emyr
check the vid out, it moves to the left especially. Apols in advance for portrait but I oculdnt hold my phone any other way..

nah, this issue has only just come about and there is a lot of movement.
I have also checked the preload on the bearings and its not that.
@Emyr it could be this.

So struggling to find a bike that fitted my specs I have become ever more tempted to go custom. However I am starting this thread to gather some advice as I dont really know what I am doing..!
I am after a road bike, with space for 28mm tyres, plus mud guards and rear rack mounts that fits me.
I own a caad10 that fits me spot on so I want to try and replicate the reach but with a bit more stack for comfort. One frame I saw that would have been perfect if it was still available was the tokyo fixed wide open.
my caad10 has the following stack/reach:
reach:368mm
stack: 517mm
I copied in the geometry of a 50cm tokyo fixed wide open as much as I could and got this:
reach:346.1mm
stack: 518.8mm
so it looks like I can increase both the reach and stack a bit. Hopefully a slightly longer toptube will help with toe overlap.
One bit where I have no idea what Im doing is designing it so there is enough clearance for tyres.. I copied the chainstay length of a geneis CDF (425mm).
The other decision is wether to go disk or not - disk would solve the tyre clearance issues with rim brakes, although the tokyo fixed wide open seemed to be ok with rim brakes.
