Reddit reviews Tektro Alloy Cyclo Cross Brake Levers, 24mm Clamp

This is true but with a caveat: mtb levers will not work on bullhorns bc they can't get around the bend of the bars. If you do decide to go with pull levers you need to look for cyclocross levers, otherwise known asin-line levers. There are those out there that feel this unsafe because it functions differently than the typical set up but imo this is a totally acceptable route to go, and several single speed companies ship new bikes with these levers and I've often run then this way myself.
