Front brake on Worksman Low Gravity Cycle Truck
I love the Worksman Low Gravity cycle truck--locally made, low budget, amazing cargo capacity, super-wide parking stand. But the greater stopping power of front brakes are a requirement for me in the city riding I do. What are thoughts on adapting this bike to disc, cantilever, V-brake, or drum brakes on the front? Ordinary caliper brakes are out because the cable will interfere with the frame-mounted front rack, and I anticipate this would be a problem for the other brake types without some careful thought.
On cable routing, I've seen other cycle trucks (e.g., the lovely Huckleberry) that route a disc-brake cable through the steerer, though I can't discern where exactly it exits (at the crown I expect). I've seen a cantilever brake with the cable routed behind the head tube. And it looks like the Workcycle Fr8 is routed with zipties closely along the the headtube and then the fork for a drum brake. I don't favor the drum brakes I've used in the past, which have been weak on stopping power. Likewise, for cantilever and other rim-stop brakes, I prefer alloy rims, so that would involve a wheel swap or rebuild. I think I probably prefer disc brakes for that reason, and have seen fairly easy wheel conversions. Are there pre-made 20" disc-brake wheels?
For attaching the brakes, any thoughts on braze-ons vs. adapting a pre-made fork? The front wheel is 20", and of course the steerer needs to be much longer than that on a BMX. Can I use a folding-bike fork?
Thanks for the help! Bonus points for helping figure out how to wrestle a fully-enclosed chaincase onto the thing.
