When I received a Rawland Nordavinden demo bike for review some time ago, it was fitted with Silver Bigmouth sidepull brakes. The Nordavinden model is made without cantilever bosses, intended to be used with either sidepulls or centerpulls. With 650Bx42mm tires that leaves few options for brakes with sufficiently long reach. I have tried the bigmouth sidepulls before on a 650Bx42mm tire bike with upright handlebars and the stopping power was fine. But it proved decidedly less fine on a bike with drop bars and road levers. The braking wasn't terrible, but not as strong as I wanted. So when setting up a Nordavinden with my own components two months later, I decided to go with centerpulls. The choices were: Paul Racer or Dia Compe 750 brakes. The feedback I'd read about the Dia Compes was pretty good, so I bought those, since they are the considerably less expensive option. To my disappointment, the braking power was not much better than it had been with the sidepulls. I rode the Vermont Fall Classic with the Dia Compes, but had to watch my speed on steep descents, particularly once it started to rain. I was now feeling a little dispirited, because there was only one option left. Trying to not get my hopes up, I bit the bullet and bought the Paul Racers several weeks later. To my immense relief, they work. They are expensive. But they are US-made, and, more to the point, they stop my bike.
In fairness, I should note here that I know riders who useSilver Bigmouth sidepulls, Tektro Bigmouth sidepulls, and Dia Compe 750 centerpulls on fat tire roadbikes without issue. However, my grip strength is weak and I have damaged nerves in my hands. Braking power with the combination of road levers and long-reach brakes has been an ongoing problem, including on bikes built for cantis. It is useful to know that Paul brakes are an option that works. The Center Mount version of the Racers does not require special braze-ons and can be used on any bike that accepts sidepull brakes, provided there is enough steerer available for a cable hanger.
Paul Racer brakes can be purchased from the manufacturer directly, or ordered via your local bike shop. The company is based in Chico, California, where they have been making parts since 1989.
