Del, the info about the reaxal kit is on Tacx NEO FB group with a link to the how to video at Drew Tacx Faqx site. This is a C&P of a recent post and a link to the UK maker/supplier.
“ If you would like to have one right away, you first need to know your axle type and frame spacing, and whether you use any spacers with your non drive side insert on Neo. Tacx have wisely moved away from the mode of using spacers to account for differences in axle length because a modular solution is a weaker solution. More convenient, yes, but weaker. Therefore ReAxle is a single piece, so you need to be pretty exact about what you are ordering. We will cover all of this in the video, so if you are not sure, just hold out a bit longer.
Once you have all that information, simply send an email to
etowartengineering@gmail.com (Euan Towart is the engineer who brought this product to life for us all) with the size that you need, your shipping address (to calculate shipping costs) and a phone number. Euan will then send you an invoice via PayPal. Once your payment is received, the product will be on its way to you very shortly thereafter.
All you need is a very manly torque wrench capable of at least 60Nm, and a 24mm six point socket, and you are set.”
