Specialized Tarmac on Wahoo Kickr

Equipment
#1

Hi,

I’ve got a tarmac SL6 disc with a 12x142 rear axle. I’ve been riding a different bike on my wahoo kickr, but I’ve been wanting to switch over to using the tarmac.

I noticed that all the recent generation specialized road bikes with thru axles have a recessed spot where the axle seats (its like a conical/cone seat). It doesn’t seem like the wahoo kickr standard 12x142 adapter works for this because it doesn’t have the same mating surface for the axle adapters.

Are there any solutions for this?

Thanks
Spencer

Not necessarily a solution, but this seems very related:

Get an Allez of EBay, both the Tarmac and Allez have the same geometry.

The Allez can then be a winter ride if you feel the need for a ride outside.

The Allez Sprint is similar-ish…

Odd, I’ve had my SL6 on my kickr core without a problem. I’m 99% sure the inner part of the dropout is flat, where the axle meets the frame. If it weren’t, hub manufacturers would have to supply end caps that fit. The outside of the frame on the non-drive side is conical, where the the thru-axle sits against the frame, but that doesn’t have any influence on the hub end caps or kickr adapters.

To mount my Specialized Epic WC (2017) I believe in my Kickr, I had to use this adapter. Maybe this is similar to what you need?

It appears Wahoo is providing updated thru axle adapters for the kickr/core:
