I used to think that 50mm tires were pretty wide, until I built up this frankenbike thing: a Surly ECR 29+ frame built for gravel, with a mix of mostly Shimano 105 and SLX 10-speed components. And the old scott aerobars are not for any speed records, they're more for additional hand positions. I usually keep the 75mm wide tires inflated to 7 to 9 psi, and it rides great!
