The RC family is made up of five different models, starting with the $2999 entry-level bike spec’d with a Shimano 105 drivetrain. Our SRAM Force test bike sits slightly upscale for an additional $400, but still below the $5299 asking price for the model that runs with the Shimano Ultegra Di2 electronic drivetrain. Sure, batteries are all the rage these days, but is it worth the extra $2000? Not in our books. Yes, the Di2 shifters work great, but so, too, do the mechanical shifters, and the $3399 price of our test bike is what makes the overall package so attractive. Yes, the term ‘trickle-down’ is a popular one when it comes to talking about the economics of purchasing bikes or bike technology advancements. Whether you believe in the former or not, well, that’s none of our business, but bike tech is our business. And when it comes to the BH Ultralight RC, we definitely believe that the trickle down worked.
