I just received my S40. I can pick up an old-school mag trainer for $20 at the local pawn shop. What do I need to adapt the trainer to a thru axle?

Hi,

You need a special through axle. There are many types on ebay e.t.c . Here is one https://www.ebay.com/itm/195471663777

Classic fluid trainers are better though. (Saris/CycleOps fluid2 or Kurt Kinetic). You can pick up used ones from ebay for about the same price.

ak-tux Thanks for your reply.

This is something that I only intend to use once while setting up the fit of the bike. I want to set up a camera and record video to help determine proper fit.

I personally would rather take sharp objects and shove them under my fingernails than ride a trainer. So this is a one time thing.

I have several old skewers in my spare parts supply. None of them are long enough to go through the long front axle of the S40. Could I simply cut the skewer in half, put one into both ends of the thru axle that came with the bike and use the trainer to clamp and hold everything together - just long enough for a good fit.

Maybe write an email to @Robert Holler ( "support at cruzbike.com" ) of Cruzbike for advice on the correct length of the thru axle adapter for a classic Turbo Trainer.

My S40 is the older type( year 2019) that came with quick release not thru axles.

On any trainer through axle or QR - you will want to use the stock one that we provide with the bike. Most of the stock off the shel QR's ad through axles that come with trainers will be too short as they are designed for upright bikes - where ours are longer as we have to account for the wider overall difference we have due to the chain stay that has to be captured over the fork.

You’ll need a thru-axle adapter kit, which is cheap and easy to install. Just make sure it fits your S40's axle.

To adapt an old-school mag trainer to a thru-axle, you'll need a thru-axle adapter kit. These kits typically include a new skewer or an adapter that fits your trainer's resistance unit and works with the size of your thru-axle (e.g., 12x142mm, 12x148mm). Just make sure you get the correct one for your bike's axle size
