Resolved: Wahoo Kickr Freehub Binding with TA (watch video)

[kppolich]

Hello Paceline,

I'm curious if anyone else had a similar issue when putting their TA bike on their kickr. Video below shows some I have this email out to Wahoo, but I'm hoping this thread might spur some thoughts I have missed.

2017 Wahoo Kickr with wahoo supplied 142x12mm end caps.
Ultegra R8000 cassette, new Red22 Chain, Tarmac 12x142 rear TA used.

Email to Wahoo:
Previously, my kickr has performed flawlessly while using a quick release specialized allez. I have since sold that bike and replaced it with a new 2019 tarmac pro disc, which uses 12x142 TA. I used the Wahoo supplied end caps for 12x142 and now my free hub is binding when using the stock specialized TA. I have removed the cassette and cleansed and regressed the freehub body/shim. The issue still persists. Drivetrain is new, and spins perfect with a wheel installed. This issue is unique to the bike being on the kickr. Resistance spinning both ways as far as I can tell.

I recall a friend having the exact same binding issue with a previous generation Kickr when setting up a 142x12 with endcaps. I believe the solution was to get slightly different endcaps from Wahoo...something to do with the vintage of the Kickr and the compatibility with one set of endcaps vs another.

That was my thought too. This is a 2017 model and i'm using the stock 12x142 end caps it came wtih.

Resolved, turns out during the conversion from QR to TA I reinstalled this with signifcantly too much torque.

6 N⋅m and we are good to go!
