Cross-check is one of the most versatile frames you can get, and I've seen a few of them on brevets, but if I were in the market for a budget brevet bike, I'd be looking at complete bikes, Masi Randonneur, Velo Routier, or one of the many gravel or touring bikes. If I were building a bike up from a frame it wouldn't be a cross check or have any shimano parts.
