I’ve just tried fitting my new 2021 Trek Emonda SL to my Wahoo Kickr Core with the 142mm adaptor kit as provided with the trainer and it doesn’t work!
Instead of sitting flush against the non drive side drop out, the raised section of the adaptor rests against the carbon. Wahoo mentioned they hadn’t tested compatibility with this frame yet but that it looks like my bike is not compatible!
Not sure how I’m going to get any riding done on the trainer any more?!!
Can you get a couple of washers to fit inside your drop out?
It might not sit all the way in the cup, but for the ~2-3mm it should be ok?
Might be enough just to spread it out a touch
@alexgold123 - The adapter I’m showing is either 142mm or 148mm depending on which way round you put it (142mm in my case). The only other adapter in the kit provided is for 130mm / 135mm quick release systems.
@jondixon - I like the idea of putting a couple of washers in to add to the tolerance however this will mean the thru axle will only be partially screwed in which I can’t imagine being ideal for the frame or axle over time?
@mcneese.chad - the video makes it look like it’s as simple as just choosing the right width adapter.
The way they’ve designed the adapter to cater for 142mm and 148mm thru axles with the raised section in the middle looks like it’s going to be incompatible with any bike frame with a non drive side dropout that’s set back into the frame by more than a couple of mm.
No so easy to find anyone to do that here in
London, England it seems. Have tried 6 machine shops and they all say they don’t have right equipment or haven’t gotten back me.
Any machine shop should be able to do this work for you. They really just need a lathe which i can’t really image a reputable machine shop not having. My guess is that you are either not explaining the job correctly (a drawing is key), or they cannot be bothered with such a small job.
You might ask around to see if anyone in your local cycling community knows of someone with a lathe. Otherwise, you might go on some machinist forums to see if you can find a local hobbyist machinist that can do the job for you. this is literally a 30 min job including setup and cleanup.
I bet you could use a hand file and vice to remove material on the adapter so that it has a notch or chamfer where the adapter shoulder interferes with the dropout.
Maybe not the best option but I have a machine shop at my work. I could get the guys there to do it for you in no time. Just pay for shipping and have a drawing/hand sketch of what you want.
Unfortunately, I’m in Michigan, USA, so not too close to you.
But I agree, there should be a local Machine shop that can do this for you for very little money.
Amazing, the only two new disc bikes I like (Emonda, TCR) are both incompatible. Wahoo doesn’t welcome those of us who still prefer the look of non dropped seatstays
