I use a similar setup to [MENTION=396646]Spaghetti Legs[/MENTION]: Wahoo kickr smart trainer and an 80s Lemond road bike. You don’t need a rear wheel, and I think my spacing is 126mm. Just did a Zwift workout as it snowed a couple of inches here yesterday. Zwift has made indoor riding a thousand times more enjoyable than previously when I was on a wind trainer.
