- Product Development: Disc brake road fork. I have some concerns about road discs; and Bicycle Retailer and Industry News just printed an article about one of the challenges that not many are discussing: heat dissipation in discs for road applications. In short, the European standard is that discs “must absorb 75 watt-hours of energy over a 15-minute period.” In riding terms this equates to, for example, seven descending switchbacks at a 7 percent grade when slowing from 50 mph to 11 mph. Therefore, I don’t think 140 discs on road bikes are going to be around for long. Even 160’s seem under the borderline. Lennard Zinn writes that caliper overheating on road bikes, “[…] indicates that calipers, master cylinders, rotors and fluid volume all ought to be greater to counteract the problem […]” Making road bikes heavier? Not to interesting for most roadies.
- Project Management: A lot happening with Honey Bikes right now. A couple of prototypes in process – one of which is a randonneur bike. Working on some industry press. Finalizing some 2013 paint colorways.
- Product Development: Randonneur carbon fork: Randonneur carbon fork: I think I’ve got a wiring harness set up figured out. Testing it tomorrow, maybe. Also came up with a solution to internal wiring conflict with a lifetime warranty. Punching holes in carbon is not conducive to product longevity – not without some tricky problem solving and testing.
- Product Development: The Seven Cycles low-mount disc dropout is back on the map. We’ve decided on a direction – one of about half a dozen we explored – and now we’re wrapping up details and some testing.
- Time Marker: Stumptown saves the day. twitter.
