  • 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.
