Dolan ADX Titanium Road Bike

Are these OK? Let me know if you need more.

One last picture, if you would be so kind, or you may just be able to answer it?

See the photo below, this is my Tailfin rack mounted to my Kinesis Ti GTD

As you can see the Tailfin strap fits nicely around the seat tube just under the seatpost clamp. Is there enough of a gap under the seat post clamp on the Dolan GXT to do the same?

The Tailfin strap is maybe 26mm wide if that helps?

The gap on the Dolan is about 19mm (inc. the weld radius), see pics below, (the last one shows a 26mm dimension to simulate your Tailfin strap:

Could you modify the strap on the Tailfin somehow?

Thanks for taking the time to take the photos, really appreciated.

Looking on the Dolan website l suspected as much, which is a real bummer to say the least!

I think if l clamp it above the seatpost clamp then it will put the rack at a silly angle. Its hard to gauge really as the frame geometry is slightly different.

The other option is to mount the Tailfin rack on the pannier mounts as opposed to the thru axle. They are much higher up than the centre line of the thru axle so it would then clamp above the seatpost clamp okay and keep the rack level, l think?

But by doing this really defeats the purpose of the 'quick fit" Tailfin rack!

No problems, glad to help a fellow CycleChatter.
If it helps the vertical distance between the centres of the thru axles and lower rack mount bolts is about 50mm, so if you were to use those I think it would put your strap comfortably around the seatpost, above the seatpost clamp about where the plastic clamp is on my seatpost.

It would also mean the the rack and mudguards would need to share the same mounts on the frame. Which again isnt a problem, other than the need for two lots of M5 bolts of different lengths to allow for the mudguard to be mounted on its own or with the rack.

After further investigation on the Tailfin website, it seems that you can also buy "screw in bobbins" for want of a better description. They screw into the M5 pannier mounts on the frame, then the rack just clips onto those like it does on the thru axle.
The only issue l can think is if the thread isnt long enough to allow for the mudguard stay as well?

Or, you can buy a adaptor kit and screw the rack to the frame, but l prefer the first option l think. If l can't fit mudguards l guess its not the end of the world, shame but hey ho......

I'm not really into bike racks, but on the Tailfin website I see they sell a 'connector' with an angle which seems to be intended for use cases like yours? This would keep the rack level, clamp onto seat post and still use the thru axle?

Sadly its not quite as easy as that lm afraid. You get two connecting arms in the fitting kit, one straight and one angled like you have shown in the picture.
Unfortunately neither connecting arms makes it any better l'm afraid.
What it needs is for the connectiong arms to be adjustable in length, that would cure all the problems.
Ive even looked at maybe cutting it down and redrilling the hole, but of course, thats much easier said than done!!
