Think he'll be fine on the tarmac? If he went with a dimension riser bar and a 50mm stem he could probably achieve similar geometry without the stack height. https://www.dimensionbikeproducts.com/products/handlebars/riser_barI'd be worried ripping it out of the steer tube. How does it attach? Probably clamp like a stem. That's a lot of leverage.
